WOO 3 Jumps Higher than WOO 2? Kiteboarding Sensor Review

[@DutchDashcamVideo]

just ordered the woo 10.0 so I now can jump over 50m

[@timwatterman401]

I gave up on the WOO in its first generation. I realized that it wasn't at all accurate and that my "highest" jumps were more than likely outliers. I also got tired of the whole competition thing and trying to track other people on their WOO's. So much easier to simply rig up and go and not worry at all about whether or not the battery was charged, if I actually turned it on, if I measured up to other kiters, if my WOO is supported or not, if I have the latest WOO, if if if. Excellent job as usual!

This is great bit of work and has all the facts to back what you are saying. I'm sure all manufacturers of these devices will not like what you have posted. I've used the North PIQ and have noticed massive issues in my jumps vs a friends readings. It's all a money making racked. Plus we loss sight of why we do this sport. For the that feeling of flying regardless of height as long you are having fun. Ditch the tech and enjoy your next session. Good winds to all.

I have a PIQ and it has the same issues. It generally shows big jump = big scores, but changing to a different PIQ shows very different heights. They are a bit rubbish.

Thanks so much!

[@oskarhellsing7837]

After analyzing a dozen or so units and users in our comunity, we have reached a few conclutions. 1. Woo does not work very well on a foil board. Woo them self has also stated this. 2. Woo 1/2 seems to miss more jumps when the rider is using a foil kite due to the often very soft landings. Not sure how the v.3 works with this. 3. All Woos are not created equal! I've done a bit of testing with 2 different Woo 3.0 on the same board. They vary dramaticly, so much that you can't really say that 3.0 jumps higher than 2.0. It depends on your individual Woo. So if you want to get on the top spot, try a few different devices, one will most likley give you one or a few extra meters. 4. If your session feel of, report it to Woo, they will look at it and remove any "incorrect readings". We only talk about "Woo meters" now since it's not the most accurate device ever conceived...

[@m2nolte]

Boo Woo! Great video by the way. I love the amount of effort you went through to put this together. Very thorough. Every jump recorded on video, wow... By the way, your vlogs are great. I have watched some of your older holiday videos and really enjoy your vlogs much more. Please keep them up. I know it's not easy to record each session, but as a 50+ progressing kite boarder, they certainly motivate me to get out on the water.

[@5n2]

Woo - is a kite arcade. Goal is to reach highscore. Of course where was no waiting, what it measures height. =) If you start to play, you must agree, what sometimes it is not your skills, it is your luck. Awesome video. Thank you for great work.

[@rasmusarvidsson2590]

[@ronblume3071]

An excellent analysis & beautifully presented. I don’t have a woo but, in spite of their inaccuracies, it sounds like you & your friends have had some fun chewing the fat about your sessions & your woos on the beach afterwards. As someone new to kiting at 65, any air I’m getting is a great thrill, regardless of having been a high flying windsurfer & snow skier for many years. The greatest joy of our sports has to be our communion with like minded folk who savour & acquire various degrees of mastery over, what mere mortals think of as “bad” weather......even if it does amount to us standing around shivering while talking shit after an epic (a relative concept) session. Thanks & you can count me a subscriber 👏👏👏👍

[@s2oooo]

This is why I love the PIQ you can instantly see the height of the jump. My 9 m Evo flat water is always 7.5 to 7.9m . You know when you've got a big one and you can instantly see if you was correct.

Did Woo ever comment on your report? It would be nice to hear from them and for you to post an update. If they refuse to comment, that is also telling and important. Again, well done.

Awesome work! Really appreciated, and hopefully the Woo team takes this as hard but needed medicine. They should hire you haha. We all like the Woo and big air but it’s essential it’s accurate, I know many people have gotten soured because they pretty much knew this was going on. If Woo improves accuracy it will end up getting them more sales in the long run.

Great factual presentation with brilliant stats.... We'll done! We have a wall with a statue at the end standing 19m high. I've been above her but woo said 13m. Here's a maths question..... If line length on average is 25m incl the rider and leader lines. Then how high is a kite when it's at 11 or 1? Been there.... And at 10 or 2? Been a I've there!

[@OurKiteLife]

Thanks! Interesting to hear you've experienced the WOO underestimating your jumps. Having something with a set height for reference is probably the best way to really gauge how high you're jumping though :)

[@curtnobrain4024]

Great Video. That was a lot of work to put all that together. Thank you.

[@OurKiteLife]

it sure was :)

[@scottgyver2745]

It also depends on what style of kite you have. C-kites measure higher because the acceleration up is faster. The PIQ is a bit less acurate than the woo but has an algorithm that makes it more accurate over time. The advantage of the PIQ is that it displays your height on the device right after the jump which helps with jumping progression. When you get instant feedback you can make adjustments accordingly. I still think the woo is more accurate than the PIQ, but the PIQ is useful for jump progression.

[@OurKiteLife]

Interesting! We’re hoping to try the PIQ soon to see how it compares to WOO, so it’s good to know this :)

[@bobbyballbag]

Great job. What a huge effort to answer a question we've been asking on the beach for years! I'd like the makers of WOO to respond to this so we can get their side... but until they do, I'm going to keep my WOO in the motorhome and ENJOY the ride and the feel of the jump and work on the smoothness of the landing (one thing that tends to be lower priority when boosting for a PB!). PS Have you tested the newer case? The clip shut cases I bought (that had the small screw holding the catch) all broke. I use the V1 rubber bands... but now I'll let the rubber flop about without the WOO on board! Thanks again.

[@OurKiteLife]

Yuri still uses his WOO from time to time and hasn't had any issue with the newer case, but the rubber band case seems less likely to break.

[@luissimoes3233]

Great Review!! Some of the issues you revel, I have already notice, when our group joins to air sessions in strong wind, with someone filming. I notice also, comparing the scores with Xensr the diferences are even higher. And since the woo is based on giroscope with an algorithm, and the xensr a gps sensor, some time i notice new jumps, jumps not so higher, mostly the jumps are lower in the xensr, witch I think are more likely to have happend. The woo have a great advantage of simplicity to download to a smartphone and share with the friends over a beer! Do you coonsiderer to compare woo and xensr? Nice job!

[@OurKiteLife]

we will definitely do a follow up video and will try to get both xensr and piq in it

[@PeteJonesF6]

I tested my woo 3, lifting it repeatedly from floor height to my maximum reach over and over again, at varying speeds and with the woo at different angles. The results were that it did miss some 'jumps'; especially those where i moved it slowly, but seemed pretty robust to expected changes of orientation. The jumps all came in within 20cm of each other, in the range 2.3m to 2.5m. Try it yourself, or look me up on Woo - Pete Jones, my session is recorded there a couple of days ago, named 'Test' I have matching video footage also.

[@Baptiste_L]

That is a very good idea !!!

[@RyanLee-cj8nk]

Great Job! You should, on your next video do a comparison of kite jump heights. Like hyperlink verse soul same rider.

[@tdj3e]

Great video. Have similar tests been done on the PIQ? I'm wondering if there is anything out there that actually works.

[@OurKiteLife]

Hey Troy we are in the process of setting up a test of PIQ vs WOO :)

[@SurfStories]

Thx. Pretty much confirms what I ve been thinking about the devices. I can see that the readings have a positive effect on trying hard to go more aggressive and measure progress but don't think it reflects reality all too well. 'Max height' should maybe be the avg of the highest 5 (or 10) jumps per session.

[@mysticpointwatersports204]

So some technical thoughts ... I find the one I have (and i mean this sincerely) feels reasonably accurate and if anything it feels like it underestimates at times ... I'm not a big jumper but I've never done a jump where I came in and said no way did I jump that high, if anything I've come in and said, really? is that all? lol So here is my thinking ... maybe there are different production batches that use different accelerometers or as Laurie said firmware issues ... Laurie, Yuri, if you guys are interested I'll give you my woo 3 to try and see if there is a difference between 3.0 models ... I'm not a woo fan boy and i only recently got one but i think this is a great video and a great question you've posed. So from what I understand the Woo algorithm is based on acceleration which can be fooled and flawed, for example what happens if you get a double lift, or if you kick up your board to do an invert .. i think that added acceleration can mess up the algorithm and translate to more than just the extra height gained by lifting the board above your head? Science aside I find the woo is fun and helps push people to jump and improve. Furthermore judging your height without a device is almost impossible especially without having initial comparisons/reference data. For me its a fun device and im glad i have one ... but for others i would recommend building a kite and board quiver before adding a woo which is more of a luxury item. And as for this video comparison and if you guys should do more of these ... I also mean this sincerely ... all your videos are great and keep doing what your doing ... it would be like telling Michelangelo how to paint the Sistine chapel! Aloha.

@@mysticpointwatersports204 in many cases ppl who don't jump too often or are new to it tend to overestimate their own height. A photo or video session typically has a sobering effect.

It would have been useful also to compare to PIQ. Except for occasionally recording a very high non-existent jump, or (quite rarely) missing a jump, I've had good experience with it (but lower readings than my WOO3 friends, but that can just be me!).

[@Aestheticnerdlife]

FYI you could use triangles to calculate the real height by taking the distance from you to the observer and using the angle delta.

[@OurKiteLife]

how do we calculate angle delta?

[@Aestheticnerdlife]

@@OurKiteLife www.instructables.com/Using-a-clinometer-to-measure-height/ Here is a good description of what to do, finding range could be a challenge but you can get range finders for $100 that can be used to track a moving target. You could also use a known location and calculate distance by using google earth tools, though I dont know how easy it would be to hit the same spot consistently doing this.

[@kiterJ]

I have 2 x WOO 2.0s which I use on my board at the same time and have had the same jump differ by 20ft in a session. The older one tends to under-read in my opinion. Since learning this and seeing your video I agree it seems there is no point to them 😬

[@paddlefaster]

Interesting results, especially the discrepancy between the two units. I don't think you can accurately gauge your height with a camera mounted on shore. You would have to be the exact same distance from the camera every time you jumped to get accurate results.

[@OurKiteLife]

Yeah agreed about camera

[@Malzbender]

Really impressive analysis AND video, thats for such quality! Clearly you guys put work into this. Just wanted to add that it might be possible to get accurate ground truth of the height of the jumps using multiple cameras and techniques from Computer Vision, specifically photogrammetry. Ive used a package by Agisoft that should be able to do it. Triangulation with 2 carefully calibrated cameras should do it too and is probably simpler. Good project for a grad student. Thanks again, impressive stuff!

[@kitelooper311]

I have the Woo 2.0 and the 3.0 and this video is a good representation of what I've seen in my experience as well. Almost every jump is way too high, and even more so on the Woo 3.0 to the point where's it a useless device. What if the Woo people actually developed an accurate algorithm, would they even want to use it? An accurate Woo would put you at a significant disadvantage in competing with other Woo users on the leaderboards.

[@JamesLamb]

Bottom line, seems an accelerometer is a crappy way to measure elevation, though I'm surprised it does as well as your tests. Maybe if you tossed the unit in the air it might give you a more accurate estimate of height, since the motion is more uniform. But on a kiteboard, your motion up and down is different from the more uniform acceleration / deceleration of an object tossed into the air. I say a different technology would be superior, though maybe more expensive? And if you want to be really consistent, the sensor should be placed at your center of gravity, not your board.

[@Demo69dan]

You Guys did an awsome job. Thank you for all your Hard work!!😍

[@davedave1330]

Were all your tests done on foil kites? Using both LEI and foil kites I know that the woo always over estimates the height on my jumps with the foil kite (probably something to do with the increased float that skews the numbers). I also notice that on a foilboard if you have a nice landing it doesn't even register it as a jump.

[@OurKiteLife]

correct all of the tests were made on foil kites

[@dpwild328]

Really like the video! I think the device should work for all levels of jumpers. if you're a huge air jumper you want to know that your jumps over 10 meters are accurate. But if you're just learning and you want to try to get a 5m jump you want to know that it's 5 meters. One thing I might have affected the perception of the jump height is how close the jump was mase to the camera. This may create a perspective that makes one jump look higher than another.? I think you should give the Woos away to whoever puts in the best comment 😉

[@Apoz]

Average of 3/5/10 highest jumps?

[@TristanKibur]

You should keep one and give me the other..... ;) Just kidding. I almost got a WOO3 with the pre-order sale but even at that price I couldn't do it. My opinion is it would have been nice to have an idea of how high I'm jumping, but I think the novelty would have worn off quickly. As it has with most kiters at my spot judging by the empty woo mounts I see on boards. I get the social aspect but like you've pointed out not that accurate so seems a bit mute. I understand the tech that goes in must cost and challenges they face, but it would have to be significantly cheaper to justify the sub par results. Thanks you for reinforcing my decision! Great video keep them coming!!! :)

I've checked every bit of data I could (including all of wetestkites'), and the woo1 is way off! Not even close to woo2 and woo3. But for higher jumps (10m+) Woo2 and woo3 don't differ - they are certainly comparable to each other.

[@rachaelinjustus1481]

What gets me is nobody ever compares the height that any of the Woo models measure, compared to the actual height of the jump. Seems logical or am I wrong?

[@neuronflow]

I am pretty confident you could also find a 5-10% difference in measurements when comparing two woo devices from the same series. It seems like that you are claiming that the woo3 measures 8% higher in general by calling it an unfair game and requesting a firmware update? How can you be sure that is not about your particular models?

[@OurKiteLife]

More testing is definitely needed. However, if there are issues (5-10%) with individual devices - that is, each device measures jumps differently - then that means that this whole measuring jumps game is even more of a lottery. Us claiming that woo3 measures 8% higher is statistically significant at p

Thanks - glad you liked the video :) The last few sessions I've left the WOO at home and had a lot of fun practicing different tricks without caring about how high I jumped! I think I'll still use WOO on those "big air" days, but I don't need to use it every time to have a great session!

[@glidentity]

It seems that the accelerometer is the one triggering the jumps and help determine the height. That's why the foilboard miss more jump (smoother pop). And why chops create small jumps. Also from the sample you show, it seems that all jump recorded lower were the jumps were you go up, float horizontal, down, with longer hangtime. Plus who care how high you go, it's the hangtime that matter 😂🤣 Great video

Shame on woo if they purposely skewed the numbers higher to bring more excitement and therefore business. I hope there is a firmware update that normalizes all versions of devices. I believe there is a simple algorithm update needed.

[@davidflusin5705]

Interesting but it seems a bit harsh compared with my experience with the WOO 2. I'm not interested in the leaderboard aspect of the WOO so I don't really care about it being dead exact for comparison purposes although it's pretty obvious from all the VLOGs out there than when the WOO shows 20+ meters it looks a LOT higher than when it shows 8-12m... To me it has been a great motivational tool and it has helped me improve my technique. I usually know by the end of a session if I'm expecting to see jumps at or near my personal best or if it's going to be lower. The interest of course being when you feel you might have exceeded your personal best to look at the WOO for confirmation. Yes, there are some hit or miss but I've never seen anything outlandish ( and I've had 3 or 4 WOO 2 as they all died pretty quickly and were promptly replaced under warranty) While I've certainly had jumps that never registered and some jumps showing somewhat higher than they felt like, it hasn't been that frequent. I'm hoping the smartwatch connection on the WOO 3 will help as it will allow you to immediately match the jump "feeling" with the WOO measurement displayed. With a bit of experience it should be possible to ignore the obviously skewed measurements and have a pretty decent idea of how high your jump was and improve your technique accordingly Bottom line is, if you're mostly competing with yourself, it's a great if flawed help.

[@OurKiteLife]

Thanks for comment Dave. Our intention was not to be harsh on the Woo. Originally a few of our friends got Woo3s and we noticed that they started posting jumps higher than they appeared to be, so we decided to investigate. Overall we love the idea of the Woo as a tracker and for the most part we are happy with it as it provides a reasonable picture of your jumps during your session. Our main takeaway was that focusing on an individual jump, especially the highest jump, could be potentially misleading as that jump can be an outlier. We suggest looking at the average height of your jumps. Secondly, we did find that the Woo3 does report statistically higher jump readings than the Woo2. In the end, we still occasionally use our Woos , we just don't give a whole lot of meaning to the highest jump anymore.

[@dvrsflrs]

Great video

[@JoaoGuilherme-og6vg]

Unfortunately Woo is VERY inaccurate... It does not measure height. It estimates, based on accelerometer. What we see everyday is beginners jumping 2 or 3 meters and Woo telling them they are going 7... 9 meters.. Sold mine.. waiting for improvements in technology

[@Baptiste_L]

Exactly. To get an accurate height of jump, you could use an altimeter (but a jump is to fast to give you a good result) or a barometer (but you'd have to calibrate it precisely before each session and probably during a session if the weather changes). But still, it is a very good and interesting video. I don't have a Woo but I'm thinking to buy one just for the fun.

[@JoaoGuilherme-og6vg]

@@Baptiste_L that's right. It is a good video, as It compares many situations and put on perspective the Woo accuracy. I thought it would not be fun to use a device that renders significant alleatory errors. It's like a watch that cannot tell you what time it is. It goes without saying that many folks use Woo for competition, which causes a lot of annoyance with this errors. A few weeks ago, a friend jumped maybe 9 meters visually and Woo pointed 15.7 meters... the result was he was the champion of South America that day... Anyway, I see many people having fun with the Woo, and I will buy one as soon as It gets better.

Mine were much more similar, most jumps within 3-5% difference, but Woo3 definitely had more outliers, a few as much as 30% higher than with the Woo2, - there are a couple of sessions I did not save, - to still have a chance to beat my own record on a good day. In your review, the one outlier you focus on, - seems that it reported 3s too early take-off and a few meters too high jump, - which may fit with the Woo blog comment that they detect the landing, then search back for the take-off, and then compute the curve (?)

[@OurKiteLife]

could be that they detect the landing. That was the only outlier with a different time stamp thought. The other 8.6m outlier jump had identical take off and similar air time

haha WooGate!

[@strusurfshop]

nice work guys

[@kitingholger9826]

Great work!!!!👍🏼🏄🏽‍♂️🦇 Thought about buying a WOO...but now will continue enjoying y sessions without it and wait for improved technology....

[@MrCalifornia1234]

I don’t think the woo will be sponsoring you. 😀. Awesome analysis. 👍

[@OurKiteLife]

Haha no - I don't think so either!

[@TKM11370]

You missed one thing that I've brought up with woo and that is around speed of leaving the water. Not your forward momentum but the ping you get when getting ripped off the water. I've got an experiment running to try and work out which is better, getting ripped off the water or going high with less momentum.

[@axarothfiefa6676]

That’s an interesting idea. What are you suspicions so far?

[@TKM11370]

@@axarothfiefa6676 So far, if you leave the water slower, like you were going off a wave and sending the kite, you will get a higher score and will be quite accurate (give or take a few ft). When ripping off the flat, maxed to the crackers on a 10m kite in 35 knots, the speed you leave the water feels like the woo can't quite catch up. I am a heavy guy so I jump in a different way to most. I have to leave the water mega fast to go high and it seems when I do I get weird readings. One thing I will say is that the Woo3 does understand downloops. As you guys who ride foil kites know, when you do a downloop on the way down from a jump, more than often you go back up again and stay in the air for longer. My Woo2 never understood these and I have had jumps where I am doing 2.5 downloops on a 15m Sonic FR. There is NO way you can do that many downloops and register 6 seconds. On my Woo3, I get the 9+ seconds it actually took.

[@PeteJonesF6]

@@TKM11370 Hey Tony. I suspect this is down to the sampling frequency. I have a suspicion that the woo3 has a higher sampling frequency to that of the woo2, and hence results in 'more accurate' jumps - which of course it would, with the integration occurring over a shorter timestep. Taking it to the extreme with a heavier rider getting ripped off the water, it is perhaps that the sampling frequency, whilst higher still isn't high enough for this very explosive motion. All in theory of course :)

[@PeteJonesF6]

However they do say that they integrate on the way down also, which should even things out a bit. Perhaps the result is the average of the two, in which case you will still get penalized, but less so.

[@DJStroble]

dang, your videos are on point

[@matthewmoir8627]

Do the gopro's and revl as well!

[@watersports34]

Thanks a lot for this video !

[@pcondes]

great job!!

[@A_Canadian_In_Poland]

This is the opposite problem to the iHealth Wave Swimming Watch; I found it underestimates the actual swimming time by almost 25%.

[@wiktorjajcarz448]

Excellent video!

[@OurKiteLife]

Thanks!

[@jakke1975]

I trust what you're saying about the WOO's (lack of) accuracy is roughly right, but how is your way of measuring any more accurate? You should approach this in a much more scientific way to get proper results.

[@OurKiteLife]

Not disagreeing with you, we have a plan in mind, jumping over 7mninflatable buoy to measure accuracy. Will have to wait till we go back to OBX to do it.

[@plouffemtb7623]

Does anyone know where in Toronto that spot is?

[@OurKiteLife]

This video was filmed at a few different spots, including Toronto and St Catharines :) Send us a message and we'll let you know the Toronto spot

[@Weaselpro]

Both... devices are perfect. I want both. ^)

[@maxgiac]

Nice job, but you have to replicate this using at least 3 units of Woo2 and Woo3 in order to have representative data of Woo2 and 3 model. Actually, you just compared one VS one device and we know each device (2 or 3) can perform slightly different. So, it could be possible the difference you found is related to the device and not to the model!!

[@AdamsHadEnough]

All the more reason to doubt the accuracy of these things.

[@kite666G]

I've been kiting for 18 years never used a woo and never will it just spoils the pure fun of kiteboarding!

[@TheDvdspeler]

This should be the top comment. Woo kiters don't get it.

[@lukakovacic2342]

You should put 2xwoo3 on one board and compare

[@OurKiteLife]

thats the plan , we are thinking 2x woo3 and 2x woo2

[@brunot3861]

I feel like the woo has problems with smaller jumps.

[@OurKiteLife]

I think it has a problem with all the jumps, specifically the height number. It does more or less good figuring out that a small jump is small, medium is medium and big is big, and that what the number of meters you jumped tells you. Just because it says you jumped 12 meters, doesn't mean you did, honestly we haven't used our woo for almost half a year now

[@brunot3861]

@@OurKiteLife okay might be right , the woo works to me on bigger jumps than 5 Meters and on lower jumps I don't use it. I think that every woo measures a bit different which was a bigger problem with the woo 2.0 and 1.0 because of the non waterproofed mounts.

[@brunot3861]

@@OurKiteLife I know people who are jumping not very high because of missing wind or anything and on these sessions the woo measures weird things
