Thanks for in death video you saved me a lot of googling. I’m a new diver with 5 doves under my belt and I decided to go big with the mk3! I’ll use it for the first time this Saturday, so I’m trying to understand everything that I can before my dive so I can have some fun this Saturday.

[@TeachMeToDive]

The Garmins are certainly great dive computers and I use mine often for sure

[@MrExLoVE7]

Finally someone explained the diving features throughly, thank you very much. I only wished if you showed how the watch shows the surface interval time and the cns % after the dive

[@TeachMeToDive]

There is a timer on the watch screen that gives you a non fly time and for CNS, you should be able to go to the dive screen (after the dive) and see that :)

[@michaelanderberg]

Loved this video, thanks! Just on the verge of buying one myself and it looks like it should be a good choice!

Great video. Would be amazing if you also did a video with the Mk3i next to the Teric. Those two are the main competitors. I think seeing how they (Mk3i and Teric) behave during a dive side-by-side would be really helpful to many people trying to choose a computer :)

[@TeachMeToDive]

Noted! We will work on that for sure. We have just begun working directly with Shearwater and have a comparison coming of the Peregrine vs the Perdix 2 coming soon. We also are finishing a video on the Mk3i vs the Suunto Ocean.

[@alexg.994]

I really enjoyed the video and you made me interested in two things, maybe you can make a video on those points: 1. You set up amazing screens. Would you mind make a video on how you set them up? 2. You talked about the setting of the AI with bottles and total dive time remaining with this air. I try to set it up and couldn’t do it properly, how about a video on this? Thank you again for this excellent video. Alex

[@TeachMeToDive]

Good idea I'll work on that

[@alexg.994]

@@TeachMeToDive look forward to see those. I am also a big fan of the Garmin Mk3i. But think the user guide is, let’s say, not so detailed as it could be. Unfortunately, I don’t have the talent to find all the features by my self. So, I am sure I will benefit from it. 👌👌👌

[@glebm7688]

Do you hear the chirping sound when diving with a transmitter? I was told that since Garmin uses sonar technology for data exchange there is a constant sound similar to fire alarm battery running low. Ty.

[@TeachMeToDive]

With the T1 I did if I didn't wear a hood or beanie. It is interesting though, nobody else would hear it. (and after about 10 minutes, I would go deaf to it.?) I spoke to Garmin about that and, since it is sonar, it was pinging off my cranial bones and into my ear. LOL when I turned the power down, I stopped hearing it completely. With the T2 transmitter, I have never heard it, even on full power. I also know that the T2 has a considerably increased range. I have picked up my wifes gas from 90 - 100' away.

[@laminar0886]

Great video! My apologies for being so late.. I just came across it. We currently dive Shearwater (and love them), but are thinking of switching to the Mk3i for many reasons. Does the Mk3i offer your current GF (GF99 for Shearwater) in addition to SURF GF? So you know where you stand at depth. Also.. how easy (or difficult) is it to customize the dive screens? I find the Garmin manual to be very unhelpful compared the Shearwater manuals. So I could use your insight on that as well. Someone asked if you could make a video showing us how to customize.. and I 100% agree that would be VERY helpful. Thanks!!

[@TeachMeToDive]

GF99 is "coming" at some point, there is a kind of GF 99 graph currently, but it isn't as clear as just GF99 on the Shearwater. There are a lot of ways to customize the Mk3i for sure and easy to add additional screens to tap through. I have one screen that I have gas and a compass on that shows my NDL/DCO as well on :) As for ditching Shearwater. It would really depend on the type of diving you do. I use mine as a second computer to my shearwater and do a lot of tech and high altitude diving with them.

[@1ofthefam]

Did you program the tanks through the watch or the dive app?

[@TeachMeToDive]

On the computer itself.

[@IDive2]

Excellent video. My mk2i got held up well for a few years but eventually gained a nice long scratch on the glass. Love my mk3i but wish the numbers were as large as my mk2i in dive mode.

[@TeachMeToDive]

Switch it to big numbers😀 they may be smaller but the resolution and clarity is SO much better

[@IDive2]

@TeachMeToDive Even big numbers, the numbers seem a bit smaller, and you lose displayable info. While the screen is considerably clearer, it would have been fantastic if they didn't mess with the digit size or at least gave an option to size it back up.

[@tattsenglee733]

Would you recommend the 43mm or 51mm as a 24/7 everyday smartwatch? My wrist is around 18cm.

[@TeachMeToDive]

As a daily I wear the 51 and love the size during a dive as well. My wife wears the 43 as a daily, but has a little challenge with seeing 2 tanks on the display. For one tank it is great

[@ekjellgren]

​@@TeachMeToDivehow big is your wrist?

[@ThomasMadrange]

Awesome video, thanks a lot! I have two questions however: 1. your last deco stop seems to be set to the highest available value in the settings (20ft), is there a particular reason? vs. the usual 3m last deco stop in the tables? 2. on my mk3i, the safety stop only triggers after a non-deco dive. I get no safety stop during a deco dive. Have you experienced something similar? My settings are: High GF 85% Low GF 85% PO2 1.4 Safety stop 3min Last deco stop 3m Thanks in advance for your time!

[@TeachMeToDive]

Great questions. 1. I keep my deco stop at 20 with the understanding that I will always do a safety stop at 15' for 3 - 5 minutes and a slow slow ascent from there. By doing this, it allows a slower off gas and less of a stress to the tissues by not allowing you to approach m-value as quickly. Also, just clarifying, there is a difference between a deco stop with a ceiling and a safety stop:) 2. I haven't had an issue in which the Mk2i or the Mk3i haven't given me a safety stop after a required deco stop. I do have another computer that has issues with that, but not with the Garmin line at all. 3. You GF low is really really high, and doesn't really build for a comfortable of a safety margin. While in light deco, this really won't be an issue, bigger dives that will require more deco and into trimix this isn't the wisest idea. Your PO2 is fine and remember you can use a PO2 of 1.6 for accelerated deco (decompression blends). I would suggest reducing that to 50 instead. Remember, the GF low is the depth of your first stop, GF high is the length of your last stop. The computer will build a path for you between the two and assist in your ascent. I have a great video on GF 99 GF 99 kzbin.info/www/bejne/fn3MfqeAiLKWa7M Simon Mitchell DCS kzbin.info/www/bejne/g3WvcoBmjM2jZq8

[@ThomasMadrange]

@@TeachMeToDive Thanks a lot for all this, I'll have to double check with Garmin support then, it seems like my mk3i is not doing what it's supposed to do. On the low GF topic, it's intentional. All the recent research that I've gone through as well as CMAS training material advises to use equal GF parameters for air dives, preventing deep stops that are now considered undesirable with air. It does change with trimix however, I fully agree.

[@TeachMeToDive]

@@ThomasMadrange I have seen a few people doing the matched GFL/GFH and I disagree with it. But, in recreational and light deco, it really doesn't have an impact at all. I would prefer to use one GF set, with smaller adjustments for things like cold, lack of rests/hydration etc. Less confusing and less chance of being missed in the predive. In plotting it out. The GF low has a hard time kicking in and making very little change at all to the overall dive plan. It starts to affect your dive around the 6 - 7 min and beyond deco obligation and sets deeper ceilings to help build a more gradual off-gas. Overall, I would still rather do a GF low of 50 and a variation of my high between 75 and 85 (depending on how I feel and how big of a dive I am doing :)

[@timpower124]

How did you get the Mk3i to display the ascent bar that big?

[@TeachMeToDive]

Its default that way

[@davidb5195]

Great video

[@TeachMeToDive]

Thank you

[@peterpanci78]

Hi what do you think of g1? many thanks

[@TeachMeToDive]

for a daily, hiking and sporting watch, it is darn near bullet proof. For a dive computer, it is difficult to read and use. It is very small and mono-colored LCD screen. I would never use it as a primary, or rely on it to be a secondary.

[@peterpanci78]

@TeachMeToDive Thank you very much. I appreciate

[@vonnearnelgonce6523]

Thanks for the great video! Question though, I have the MII, and it is not going to the 3 min safety stop after it is cleared from deco. Literally just got out of the water with a dive that was exactly the same as the one you are demonstrating and it did not give me a 3 min safety stop. Is this a setting somewhere I am unaware of? My watch software is up to date, but it's done this 3 times. It bugs me-I want the 3 min safety stop to show.

[@TeachMeToDive]

That is a great questions and one that we hear a lot. I posed this to Garmin as well for a more detailed answer. My, simple answer is this: If you spend enough time at safe depths and your gradient is considered low enough by the algorithm, it will skip the safety stop. Garmin said this: Once it is a deco dive the algorithm will prescribe sops at 10ft increments. Many divers will choose to extend their shallow stops for safety reasons, but it is also important to communicate unambiguously what the minimum TTS and mandatory stops are prescribed by the algorithm. Adding a options safety stop between the 20 and 10ft stops is something a diver can certainly add themselves if they wish. Note that we also allow the diver to set the depth of the last stop, with many divers choosing to adjust that to 20ft. Communicating an optional stop after that could be confusing to divers after they have completed mandatory deco deeper than a typical safety stop would be.

[@weibinglee5297]

I still can't get the torchlight on my Garmin Descent MK3i to work during a dive. Do you know how to turn on the torchlight during a dive?

[@TeachMeToDive]

Hmm I've had it come on in sos when I hit the help , but not tried it for an actual light during a dive. I'll dig into that tomorrow during some dives

[@stephanwilliot2324]

Does the Garmin subwave sonar technology still have that annoying beep? Wondering if I would use all the functionality it is about 500EUR more than a Shearwater Terric/Perdix 2, which is what I wanted to go for. All three products seen great.

[@TeachMeToDive]

I haven't noticed the sonar tones at all with the T2, but we have only been doing cold water testing with it. This is an area that they mentioned had been improved. I do know, when we put the T1 on low power mode, this helped a lot and we stopped hearing them when in the pool. As for Garmin vs Terric. GARMIN wins, BY FAR!!!! Garmin vs Perdix 2. Pretty even when it comes to being a dive computer. I still like the Garmin here for it's surface/daily wear functions. For more complicated dives IE Technical trimix and beyond, my Garmin moves to second position and I use a Perdix 2 as my primary. It just handles the very complex more easily, but that is a close race as well.

[@addohm]

My mk2i has a few scratches on the screen. I got them at the start oh a dive when doning aluminum stage and deco cylinders. My mk3i hasnt had that happen.

[@TeachMeToDive]

We can tell you this, if you try hard enough, you will certainly get scratches. lol I just got one on my Mk3i from coming in over rocks during a very heavy tide. lol :)

[@desireeyoung8778]

does the 51 mk3i have more feature then the 43 mk3i? Or just a smaller screen?

[@TeachMeToDive]

The 51 mm has an LED flashlight and the 43 mm doesn't. This is the only difference that I can see, other than the color of the watch itself :) I am a little jealous of my wife's color to be honest :)

[@ekjellgren]

Also differences in battery life.

[@SGManhHa]

Why the diving interface in my MK3i is difference with your. MK3i look similar with Mk2

[@TeachMeToDive]

the general screens are customizable and since I had already customized my Mk3, many of those settings transferred to my Mk3

[@SGManhHa]

@@TeachMeToDive Actually I knew what it is. I set the Dive Display wit big number then It changed the interface

[@rocaveda9757]

Can you adjust the ascent rate? IE: 30'/min, 60'/min, etc

[@TeachMeToDive]

No, the standard accepted safe ascent rate that is suggested by Dan and the WRSTC is 30 feet per minute or less.

[@wib1400]

Can you dive again on the same day after this dive?

[@TeachMeToDive]

Of course, the Garmin series of dive computers calculates repetitive dives very well over the course of the same day and multiple days

Is the screen of the G1 as bad as it looks in this video? I can't see anything!

[@TeachMeToDive]

Neither could we. This was one of the complaints my wife had diving it for the last year. It was incredibly difficult to read during dives. While at the surface it is okay and certainly provides information, at depth, without a lot of concentration during dives, it was tough at best. Certainly not a computer I would use on complicated dives.

[@suntzuthesecond]

@@TeachMeToDive Thank you. I happened to be looking for a replacement for my Fitbit (it died the moment it touched the water when I tried to use its swim tracking features), as well as my first dive computer to go along with my freediving. I guess I should keep looking and perhaps get two separate devices instead; I don't even like the aesthetics of the Descent series in the first place. Oh dear, I think I hear my wallet squirming harder than usual. 💸

[@TeachMeToDive]

The G1 in 41mm is a very nice looking device for sure and can handle anything you throw at it. I have many miles swimming with my Garmin and it is amazing, keeps my pace, stroke speed, distance, heart rate and a ton more while I swim. Plus is is an amazing all sport computer and dive computer:)

[@suntzuthesecond]

@@TeachMeToDive Thanks for the reassurance, but the lake I train in is at least as murky as the waters you show here. A readable screen would be nice.

[@TeachMeToDive]

@@suntzuthesecond agreed. The G1 isn't a good option, but the mk3 is great for sure. I've used my mk2 in vis less than 1 foot and it was still fine😀

I've been wearing watches with sapphire crystals for 30 years and have NEVER scratched a sapphire, let alone destroyed one, which I hear is possible. A protector film is in no way required.

[@rafaeltomaszewski994]

Touch screen in dive computers is sh*t. Any random drop of water on screen and you're on different set of options xD

[@TeachMeToDive]

It is a little tricky. The garmin handles it pretty well for sure. When I get ready to dive, where I have a surface swim, I push the top right and bottom left button and it turns off the touch screen. Problem solved for sure. :)

[@Alarsonen]

"454 by 454 prixels"

[@TeachMeToDive]

LOL

[@fuexiong88]

With that price and it can't make phone calls? Why not just get the Apple Watch Ultra 2 that can make calls and dive. It's also cheaper.

[@TeachMeToDive]

There is a great deal of difference in these watches for sure. The Garmin is a hands down leader when it comes to biometric data as well as durability. The amount of true dive data as well is quite remarkable. It also is able to air integrate with 8 pods and has the ability for you to monitor your buddies gas(es). Plus send messages as well during a diver to other divers. Finally, my favorite. It doesn't require a subscription to be able to use the dive function and won't stop working if you don't have the morning update from Apple. :) Just a few thoughts :)

[@zfjames]

If that's your priority, then yep. Good decision. I don't care about making phone calls on my watch at all. Makes me look foolish talking on my watch. Apple is the only company that's allowed to do phone call/messaging integration with iPhones. As a result, no watch but an Apple watch will do phone calls with iPhones.
