Portable sonars for very small boats

[Barry Evans]

I'm heading to Vermont again in August and will be fishing for several days on the Inland Sea portion of Lake Champlain. My in-laws (their place) have a 14' Aluminum boat we use to get around; I'm considering getting an inexpensive sonar for it in the hopes we can start to ID some major structures to fish or a particularly productive depth.

I had a GPS with lake chart last year but with the limited range of the little boat we only had a few charted points of interest to fish.

Any experience or tips on these units? I might possibly try using one on my sea kayak later but that's unlikely and probably shouldn't be part of my criteria looking.

I bought a Humminbird Piranha Max at least 5 or 6 years ago, to use on a 12' porta-boat that I take with me on the RV. Battery powered, it's quick and easy to set up; the FF and suction-mount ducer & cable all store in it's own little case. It has always worked very well, even in salt water in the keys, but I don't know if they even make them anymore.
