How many holes do you drill ice fishing to finally find the right depth you want to fish? This unit will shoot thru the ice to get a depth reading but there are some limitations. Lots of air bubbles in the ice will impede a good signal and reading. I used some water poured on the surface of the ice to give a good interface for the transducer. Move it around on the ice a little and bingo, there was my reading I needed. Now instead of drilling a dozen holes with the auger I can scout with the Zebco first and reduce the number of holes drilled. The fish finding and weed/rock structure features are not so important for my application but turning the transducer 90 degrees on a paint roller extension handle and lowering in the hole allows for side scanning out to 100 feet for schools of fish. Single fish won't show.

The Zebco ZF200 CP4 Fish Finder does like it says. It will tell you if there are fish with in radar reach. Caught a 2.75 Large Black Bass the first day using it. Made believers out of my son and I.

The Zebco ZF200 is a great product for the price. It gives you a good depth readout and generally recognises fish. Is just what I wanted for my float tube.
