I made a thumper. I quickly found out it irritates the heck outta me, so I don't use it no more. And other boats that go by look strangely at me thinking I had engine trouble. One asked "Is everything ok?". 🤔
Ha ha. That would be a bad engine problem. With it back in the back and inside a compartment it really doesn’t bother me too much. I thought it would have bothered me more, but then again if it helps catch fish then Im sure it listen to air horns all day if I had too.
It will work in shallower. I don’t think you can go wrong by using both splasher and thumper. I was using it other day in 15’. I was more struggling to catch fish so was trying everything. I think it’s more effective in the winter though, but know people who use it year around and seems to work for them. We just typically don’t use it in hot weather as much.
