Hello everyone,

I've been following this board religiously and have finally decided to treat myself and upgrade from my Deeper castable to Garmin Striker 4cv.

An issue that I'm having is figuring out the best way to mount the transducer given its size/shape. I'm aware that solutions have been discussed in depth on this board but most solutions I have found were for flat bottomed transducers or older models of the striker 4.

For the GT20-TM I'm a bit confused since the transducer is curved, how much should the transducer be covered/inserted into the duct seal, it has a flaired flatten plastic portion at the top which I assume is for in hull installations so the electronics wouldn't be that far up but I don't know how far it needs to be covered.

If anyone has pictures of their setup in a canoe that would be greatly appreciated for a newbie fisher like me!

bump!

The transducer for my Garmin Echomap is like that. I have used an ice fishing transducer with its flat bottom and I have used the curved one. Either work fine by setting them into the back of my canoe and just tossing in 3-4 hands full of water for them to sit in. I run the cable alongside the seat of my Wenonah Sundowner so the cable tends to hold the transducer upright. The don't need a lot of water to make them read bottom.

If you can’t get it to sit upright on its own, here’s another option. Take an old PFD, cut it open and remove 3-4 sheets of closed-cell foam. Use marine goop (or 3M 5200 or something similar) to adhere the sheets together so that you have a chunk of foam that’s 3-4 layers thick. Place the transducer on top, trace the outline with a sharpie, and then use an xacto knife to cut out a pocket that the transducer can sit in snugly. You can use a non-permanent putty to adhere the foam to the bottom of your boat, then sprinkle a bit of water into the pocket and squeeze your transducer into the little reservoir of water. This project took me maybe 15 minutes and I had all the materials on hand.
