Is there a GPS / Fishfinder that is good for both Kayak / Jon Boat / Sailboat use? (fish finding + navigation)?

[Chuck_FLA]

I'm purchasing a Garmin Striker 4 Plus for my fishing kayak. It got me to wondering, is there a tool that could be considered portable that would work well for fishing finding (transducer) and for sailboat navigation and course plotting? I'm trying to avoid purchasing a multi thousand dollar device. Just wondering if there's some perfect piece of hardware that I'm not considering.

Thank you!

We had a Lowrance fishfinder/plotter on a previous boat that might be the type of thing you’re looking for. Lowrance is Navico’s fishing targeted brand and generally has lower cost options than their Simrad and B&G products. I don’t know much about their current models but something like the Eagle fishfinder might be worth looking into. You’d probably need to get two transducers and two RAM mounts - one to mount to each boat, but with that it might be possible to move it back and forth.

I had a Montgomery 15. I bought a Hummingbird fish finder on sale. It worked well in my pocket yacht.

It came with a transom mount transducer. Not wanting to screw the transducer into my hull, I opted to attach the transducer to the inside hull with some plumbers putty. Worked like a charm. I've heard owners use silicone caulking, toiletbowl beeswax rings, epoxy etc. You need to be sure that there are no air bubbles between the transducer and the water. This would include no hollow hulls.
