A year and half ago I bought a boat with it on and for the first few months my response is “it’s cool but I wouldn’t go out and spend my own money to buy it had it not been on the boat”. Then I learned how to use it and what I was looking at. frustrating as heck to see all of the fish that you cast at(open water) and not catch. But it is a great tool for not only finding structure like weeds, timber and in our part of the world, sunken equipment. But just watching the fish react to your bait is a learning experience. I now have 3 units, one that was on the boat, I just built one for ice fishing and now have a transducer and black box to sell. I am sure it is/was like the depth finder and gps 30 years ago when everyone said it was too expensive and it would ruin fishing, but here we are and for most places the “good old days” are right now for the quality and quantity of fish.
