Garmin Striker 4 Inside the Hull Transducer Mount | Cheap, Quick, Easy Kayak Transducer Mounting

[@shoefrmperu]

Wow, I just got into kayak fishing and no video actually shows why it’s so important to make sure the seal is correctly seated. Thank you for the visuals! Awesome channel!

[@1Cast1Fish]

Thank you, glad you enjoyed and it helped

[@robertgriffin8899]

Never heard of duck seal but I used the foam from a yoga pad. I cut it out in the shape of my transducer and then glued it to the bottom of my kayak. That way I can remove the transducer after each trip. Works like a dream.

[@ColinProft]

This was a great video. Thanks! After several hours of trial and error, this method has still not fully worked for me. I've carefully followed your directions with the installation process, but I haven't had much luck. Before I describe my results, here is my equipment list: Garmin Striker Vivid 4cv with a GT20 transducer, and my kayak is a Vibe Yellowfin 100. In order to guarantee the transducer being mounted below the water line, I've put the duct seal immediately below my seat inside the hull. That way my full body weight is pressing down on that section. I thought, "Maybe my issue was mounting it at the front of the kayak, which might not be under the water line." Unfortunately, that didn't do the trick. My mounting technique: 1) Duct seal is 1" thick before adding transducer, flat against the hull, center of the kayak (under me) 2) Transducer is fully surrounded by duct seal 3) Kayak hull is virtually flat in the center Results: 1) The transducer doesn't function properly up until about 8+ feet of water. Then it begins to properly find the bottom. 2) The 77 kHz frequency on the "Traditional" view works, but I've noticed the 200 kHz frequency doesn't 3) Similar to above, the "Clear Vu" mode is non-functional. This seems to be an issue with frequency, as the 200 kHz didn't work in Traditional Mode either 4) I have noticed that, as I approach the limits of the sonar when I get above 8 feet of water, it begins to think the bottom of the lake is fish. Fish symbols appear like crazy on the bottom Help! What am I missing? Does the shape of the underside of the kayak matter at all? Does this method simply not work right with the GT20?

[@1Cast1Fish]

Sounds like you got the technique down pretty well IMO, have you tried just tossing the transducer over the side and see if the results are the same? Could be a transducer issue possibly. I have used my GT20 with no issues and this method

[@ColinProft]

@@1Cast1Fish Potentially. I've tried putting the GT20 in the water to see if it was working properly and still got some weird results. I'll keep you posted. I didn't have issues with it a week ago, but I've been modifying my kayak recently. I used to put the depth finder over the side of the kayak. Your videos have been EXCELLENT. Truly. I've learned a lot by watching through your Striker series. It's been invaluable in figuring out what I'm doing with the Garmin.

[@1Cast1Fish]

Might be time for a call to Garmin if you still have issues even with it in the water. Hope it gets sorted out soon before the best part of fishing season starts :)

[@HonkinNJ]

I have the same setup and you except a different kayak and I’m getting the same results as you. I didn’t try it over the side though hmmmm.

@@HonkinNJ See my reply about the Garmin suction cup option. That may work for you too!

[@marthaparisidirksen2432]

Thanks for all your previous answers to my questions. Once again, this tutorial is brilliant. I was challenged with using a Garmin Striker Plus 4cv in an AquaGlide Chinook 90 inflatable kayak but figured out a solution that worked very well: I installed Scotch Brand Extreme Fasteners to both the bottom of the transducer and the bottom of the starboard side "pontoon". (Really not a pontoon but a fabric-covered vinyl air bladder) I can reach over the side of the kayak and stick the transducer into place very easily. The transducer cable then threads through a couple of loops (kayak paddle loops made of velcro) to the Garmin and I can either disconnect the cable and leave it all in the kayak, or unsnap the transducer from the hull and pack it all out when finished fishing. I can also beach the kayak and by leaning a little to port, the transducer never touches bottom because of the kayak's construction. Best of all, it works! So thanks again for all your helpful tutorials, advice, and ideas for kayak fishing. You are clearly an expert in this area!

[@1Cast1Fish]

Thank you, and awesome to see you got your setup figured out...sounds like it is working great now. There is never a one size fits all when you have so many kayak shapes, sizes, and options out there...but you found a great way to get yours working well. Good luck and any questions feel free to ask.

[@IREFUSE9]

Martha, can you elaborate on the fastener? Does this stay on the bladder when you pack up your Aquaglide?

Hey did you ever think of not mounting it to the kayak and using the switch blade tranducer mount?

[@marthaparisidirksen2432]

@@strnto8967 I use an inflatable kayak for fishing so the switchblade tranducer mount doesn't work in this case. Using a velcro-like fastener works perfectly and no holes in the shell or air bladders.

The best answer I have is, that you will need to try it. I have seen it work without issue, and I have seen a few issues. Really depends on construction of the hull, and transducer installation. The key is to ensure no air gaps and ensure the transducer is below the waterline. Some aluminum boats have 2 pieces of aluminum and that creates a small air gap that causes issues.

I just used a yoga block cut it to 1"1/2 thick and 3/4 or 1/2 width&length past the size of transducer. Tracing the transducer in center of a piece yoga eva foam block that you cut. Also make sure to cut the tranducer yoga block to fit in center. Find correct spot to glue your cut yoga block in the kayak hall glue in location you pick let yoga block dry. Then install the transducer after you filled yoga block cavity halfway with the glue you select then press transducer till it bottems out to hall making sure to avoid air gaps and bubbles let cure. Intall everything else. Buying the foam block pre made for kayaks cost 20.00 yoga block 5.00 and you have extra. Its the same eva material.

[@1Cast1Fish]

That's a great idea...check back in and let me know how it worked out...I would love to hear your results.

[@williamoneill5498]

This is a mad good idea and very interesting. I have seen others using cut out foam, even water or resin filled foam, glued to the Kayak hull. Air bubbles are a hazard with the resin method and also pretty permanent for your transducer. Duct seal seem like a very flexible option, assuming sonar penetrates it very well? Also its easy to reverse if not effective. I wonder how GPS works out if you mount inside the Kayak? I definitely want good GPS functionality. I am planning on putting a FF on my OT Predator this summer, I was going to conventionally mount by stuffing a pluming pipe down the scupper hole wrapped with duct tape, acting as a shim, with the transducer on the end snug in the recess. But now that I have seen this, I am very tempted to try it out. If I get a FF model with a strong down scan, I should hopefully get very close to a direct water mounted result. Excellent video, thank you for posting.

[@1Cast1Fish]

So most fish finders the GPS is in the head unit itself not the transducer, unless you have a external GPS puck for a higher end unit.

im sorry if its already been asked but with the 5cv if we mount through the hull with duct seal, do we get temperature readings????

I store the kayak outside on a wood frame upside down year round so I will need to remove the FF when I store it so the cell block / switch blade might be easier anyway but If I can get water temp readings through the hull - that would be better than the over the side arm. thanks!!! thanks, I just re-watched the video (no good temp readings) so im going to look at the cellblock- arm or in hull mount - thanks for the videos after I figure out the mount problem next up are the how to read the fish finder videos.

I rarely ever need to clean the inside hull of the kayak since everything seals up nice. The duct seal will be fine if just washed with a hose and such.

I tried this with a Garmin 540s in a sailboat. The fishfinder screen seems to work but the depth meter does not work at all.

The depth information is more important than the fish finder for me, so I went back to a wet well, which does work.

[@1Cast1Fish]

Sounds like there is a air gap of sorts between the transducer and hull...that is why no depth...the air kills the ping and then it thinks it has no depth. Once you add water the air gap is removed and no issues.

@@1Cast1Fish I have to revise my comment. Since I've been having issues with my depth sounder as well as the Garmin, today I replaced the transponder on the depth sounder, replacing the in-hull model with a Humminbird puck. I mounted it a bit off center of the boat where the fibergass is a thinner and used the duct sealer. Worked like a charm. I then took my Garmin and moved it from the location I had been using, which works fine with a water bath, and stuck it on a thinner area using the duct sealant. It works! I still get an occasional drop-out on the Garmin, but it only last a couple of seconds. I'll know more about how this really works after I've used the boat more signifcantly than my little test ride today.

I mount my CV in the hull without issues, and many others have as well. Some people have some issues though, so it can depend on each kayak, but most issues seem to be with improper mounting such as a air gap or not being level.

[@mindyburns7536]

@1Cast1Fish that is great, thank you. I don't know why I thought it had to be in the water. I am going to get it ready today. My husband actually put a fish finder on his kayak. He might actually fish more now. He asked me if I had an extra fisging pole he could have. The nerve of that man. Lolol. I have several, but always go out with 4. I always say there are two things of a woman's a man shouldn't touch....her food and her fishing stuff. 🤣

[@1Cast1Fish]

LOL...never give up your rods :)

[@yakin_n_bassin8203]

Not sure if this has been answered already but does it matter if the transducer is mounted facing front or in reverse? Thanks... great content... bug reason why I bought a striker 4

[@1Cast1Fish]

For most applications it will not matter...I have reversed mine for specific reasons before. That's the great thing about duct seal...you can move it as much as you want. Glad you enjoy all the videos

[@novaday8813]

Hey man so i did this for the gt20 transducer. The regular sonar works but the CV is definitely wonky. Id say the bottom/tip of the trans is right on the edge of the duct seal. The sides have about 3/4 of an inch. Should the tip and bottom also have thay same leeway? Do you think thays whats messing up the CV?

[@1Cast1Fish]

Possible, but also is the transducer completely below the waterline when inside the kayak? Also ensure the duct seal is making a good base with no air gaps...you want it thick enough to bed the transducer, but not overly thick.

[@peterk7377]

We don't have that Duct Seal stuff here in Australia. Maybe we do but a different name?? Any ways I seen a few guys using clear silicon to install inside the hull. Any pros and cons to using clear silicon?

[@1Cast1Fish]

Should work the same

[@Dogatemyhomework927]

The nocqua battery seems to be associated with Yak Attack, not available on Amazon and everyone is out of stock. I haven’t seen any other batteries that compare..

[@1Cast1Fish]

They are the best IMO, not sure on comparison, other than I like it way better than the regular lead acid type I started with. Hope they come in stock soon.

[@rickvela9126]

Thanks for a great, informative video. much appreciated. I am curious , some videos show similar installations with duck seal, BUT add water or non toxic anti freeze into the well created by duck seal. They claim it gives better readings. your thoughts ?

[@1Cast1Fish]

You can do that, its mostly because of heat build up in the transducer...the Garmin Striker 4 transducer is very low wattage compared to larger units, so no heat issue. Me and many others do it this way and no issues.

Nice video. I will follow your guide. just one question: how long regular duct seal would take to cure? Just asking because I carry my Kayak upside down on the top of my car. Thanks

[@1Cast1Fish]

Duct Seal does not "cure" it will remain soft and mailable for the most part. It is pretty sticky and should hold your transducer well even upside down. I have mine stored sideways and never have a issue with it falling.

Hi, How to mount the transducer on zodiac boat? Thanks

[@dwrdcszz]

Does the transducer come with the Garmen Striker 4 ? I don’t assume the battery does? Can the transducer be mounted in the dedicated spot on the Old town 106 PDL?

[@1Cast1Fish]

It comes with a transducer, but no battery correct. If you are referring to the recessed area for a transducer, then yes it will fit

[@georgebowman3051]

[@1Cast1Fish]

Thank you

[@alansmith4419]

I have enjoyed all your videos. Many thanks for the great information. 😊 Based on what I've seen, I think an ice transducer mounted in a kayak will work great - as long it is mounted so i9t points straight down... Any experience with an ice transducer mounted like this?

[@1Cast1Fish]

Never see or heard of it, but that does not mean it will not work...give it a shot and let us know

[@davidhendrix4612]

How well does the transducer read in the hull instead of the water?

[@1Cast1Fish]

No issues other than water temp. Some people have issues with the Clear Vu depending on mounting and boat type it seems, but no issues in my kayak

[@paulroberts6693]

Does placing the transducer over a keel guard have any impact to performance ? Like less depth, not as accurate readings, blurred images?

[@1Cast1Fish]

I would not think so, as long as there is no trapped air or gaps...but I cannot say 100% since I have never tried it or seen it done in this application...but it is cheap and simple to try.

[@ras5155]

ok Give me break. I am new to Kayak fishing and new to the Garmin Striker 4. So.... When I see the fish symbol going from right to left. ...... where is the fish? is it swimming under my kayak right to left? is it below my kayak or has it already moved past my kayak and if sho, in what direction? Where are the fish I see on my Garmin Stiker 4? Remember, I am a newby and still trying to learn this stuff. Thanks for your great videos!

[@reddysoft]

How strong is the bond between the duct seal and the hall and the transducer in the duct seal? I ask because I will be putting this in a Kevlar canoe that will be picked up and carried from lake to lake for 10 days. Do you think this will all stick together well enough to not be a problem. Meaning that... Not fall out! Thanks

[@1Cast1Fish]

It is strong, but my concern would be the transducer working through the Kevlar hull. Kevlar is pretty dense and may have issues shooting through...I would try it first just to be safe

[@reddysoft]

@@1Cast1Fish I see. I have shot a transducer through a Kevlar canoe but that was using a foam well filled with water. Worked great, but takes a little maintenance. I tried shooting the transducer through a older poly old town canoe this past weekend using duct seal and it did not work, but the well of water did.

[@1Cast1Fish]

Very interesting outcome, was there any air gap when using the duct seal?

[@reddysoft]

@@1Cast1Fish I don't think so. I didn't work the duct seal very much, just broke a chunk off, stuck it on the bottom of the canoe and then gently rolled the transducer into it to avoid any air. I just finished installing the transducer in my Kevlar and it works great, but I used marine goop instead of duct seal for a more permanent bond.

[@joshuasmith2689]

Any idea if there is a noticeable difference in return images when mounting inside the hull compared to mounting in the water on a trolling motor? Sounds like it works just fine even when having to pass through extra materials.

[@1Cast1Fish]

I have not noticed any difference. Even my bass boat has a transducer that is mounted in the hull.

[@joshuasmith2689]

Man, that is awesome. Can't believe we live in a time like this with such affordable tech that works so well.

It is pretty crazy

[@lucasschmidt8909]

I want to get a FF and do this, is it easy to mess up? The bottom of my kayak if V shaped all the way across

Not really easy to mess up since if it does not work you can pull the duct seal out and try again

[@chrisfreeman5191]

Hey man I just bought a new Huminnbird helix 7 MSI and I still wanted to use my striker 4 for 2D sonar, My boat is too small to fit both transducers on the hull. My boat is an old aluminum boat so I wanted to mount it in the hull. Would that same tactic work?

[@1Cast1Fish]

Aluminum seems to be tricky, I have heard of it working fine and some of it not. Duct seal is cheap, so I would give it a try since you already have the units

[@ryanlux7796]

Killer Vid!

[@1Cast1Fish]

Thanks a ton, very much appreciated

[@dianalarson142]

if you take the transducer out of te duck seal, can you just put it back in the space left in the duck seal ? Or should you start with a fresh amount of duck seal and place it back in the kyak?

[@1Cast1Fish]

I just reuse the same spot, unless it get messed up then I pull it out and remold it again. I have the same duct seal from 2 years ago :)

[@jimkaneko1692]

Would this system of using the putty work if I was swapping the transducer between two kayaks?

[@donwilloughby6087]

I live in Canada and my Hobie kayak is kept in a shed during the winter. While it is protected from accumulation of ice and snow it is exposed to well-below freezing winter temperatures for several months at a time every winter and the duct seal will be exposed as well. Can I expect the transducer installation to work in the spring as it did during the previous year's fishing season and will the duct seal continue to adhere to the plastic surface after being frozen?

[@1Cast1Fish]

To be completely honest I don't know...I am in VA and we do get cold winters...it''s nothing like Canada cold.

[@donwilloughby6087]

@@1Cast1Fish Well, I did the installation today and we'll see what happens from the cold weather. I've done several other in-hull installations using epoxy but each time it eventually failed because the epoxy is rigid and with the hull flexing slightly it eventually pops off. Hopefully this is the answer.

[@1Cast1Fish]

I have seen the same issue with epoxy installs over time. This should not have that issue

[@anonimous596]

another question about installing the transducer -through the hull is an option im considering I have a Hobie compass and the gt20 transducer that comes with the Garmin 4cv is pretty big. some show it installed in the built in Lowrance plate area but are concerned about it hanging out about a 1/2 inch behind the plate out in the water --- why would that be a problem? its mostly protected there and I want the water temperature feature so Id rather put it in the water if I can, if it hangs out is that a problem? the over the side option is possible as well but I dont want the extra pieces. thanks for any help!

[@1Cast1Fish]

There are alot of mounting options, but the thing to remember is they must have no air gaps...so fully submerged in water or no gap between the duct seal/boat/water. I looked at a few pics of the compass and the Lowrance plates, since I have never seen them. I am going to say that it should still work fine since the transducer will be fully submerged, just not fully protected....however I have no experience with these, so I am not 100% sure.

[@anonimous596]

@@1Cast1Fish thank you for the reply --- I found a person on Etsy that makes Garmin transducer plates for the gt20 transducer used in the Garmin cv fish finders for the Hobie kayaks that take the place of the Hobie Lowrance plate- I did not want to cut that one up because its Hobie so probably $$$ to replace, anyway it looks as if this custom one fits well holds the g20 up and in the recessed space. I ordered one (expensive $45 but still less than a new Lowrance plate from Hobie) and have not received it yet but will try to remember to come back and say how it works and installs. I just got the 5cv today and have not had time to try to instal it yet - work....... I still do not see why there would be a problem leaving the transducer exposed but not below the hull, since it is made to be placed on the back of boats and comes with a trolling motor mount so its likely intended to be exposed to water right??? another question I had is that I will have to remove the finder from the kayak for storage upside down on a wooden from - any problem with frequently unplugging unit from power and transducer cables??? thanks for great videos

[@1Cast1Fish]

Be sure to power off the fish finder before unplugging also see my other reply for more on unplugging. I also think the plate is actually used to protect the transducer from rocks and bumps...kayaks tend to be operated in shallower and rougher water than boats, so bottom contact is not unusual in a kayak. Those transducers are expensive to replace

[@johnbryant_]

When you push the transducer into the duct seal, do you leave it in even when you are not using the kayak?

[@1Cast1Fish]

Yes

[@anonymous-me]

Can this be used as a permanent mounting solution, or do you have to remount it often? I am so unfamiliar with Duct Seal.

[@1Cast1Fish]

Duct Seal is great because it never really gets hard, therefore it can be moved or reused easily. I leave mine mounted in my kayak most of the summer without issue.

[@treddshort]

what about kayak hull storage which is the waterproof bag type?

[@1Cast1Fish]

I still put a bag in the hatch with the transducer in there...guess it may depend on hatch and bag size though as some may be smaller or bigger.

Will this method work for the newer striker vivid 4cv? It has the gt20 transducer.

Should, I know it worked with the older CV and it used the GT20 as well

Does the sonar feedback change from mounting it inside the kayak haul as opposed to mounting directly into the water?

Not if done correctly

[@jojinapigkit2022]

can that transducer be placed on the side of 20° v type hull and can it be submerged in the water? thanks.

[@evanillasky]

Would this work if I use my humminbird ice helix on my kayak?

[@1Cast1Fish]

So I have not tried this with a Humminbird, but since they all work the same I would assume it should work fine. Just ensure no air gap, and the transducer mounting is still in a area that is below the waterline.

[@jasontaylor9871]

When you mount the transducer does the signal come out of the end with the wire or the end without the wire?
