I like that it uses AA batteries. Like that it has a bar graph that makes it easy to read. I like that its small enough to fit in my coat pocket. When looking for a spot on the ice I can check depths without drilling. Just dump out a little water on the ice. Put transducer on and get a depth. I walk around my area dumping water and getting reading of the bottom. Helps finds drop offs and such. While fishing cloudy water I can't see my jig. I put transducer down the hole and watch bar graph. Jig shows up as a small line and reacts to real time movements. When another line appears get ready. When bars merge usually its a fish and wait for the bite. No more wondering if they are swimming by. They will show up and you can drop or raise jig to target. Don't always use. But is a great tool that fits in your pocket and easy to use.
This is a great unit if you want to start ice fishing but don't want to spend $400 - &500 on a flasher. This unit paired with the powerpak is light, has a long battery life & picks up on the tiny jigs.
