I have used 2 of them since the first model came out. I like the portability of it from float tube to small boat.The screen is small but I mainly use it for depth and structure/weeds for trolling.The sidefinder I do like,have anticipated many a hookups when I see a fish appear at the distance my line is out.I do miss the first one I had. I thought it was better than the replacement model.Too bad the lcd went out, do not leave it exposed to the sun but I got many good years out of it.If you just want it for a float tube it will work fine. I also use it sometimes as a second finder on my larger boat.Just make sure to have a spare set of c batteries.
