Anybody out there playing with these gadgets? Or other castable fish sonars? How do they work in your ice fishing hole? Whats the battery life like on them, can you get a day of fishing out of them or do I now need a USB charger in my boat?
I bought an FishHunter 3D a month ago. It has worked well ice fishing (I have no experience with other flashers though). I haven't had a chance to try it in open water. I've only used 3 at a time so I can't really comment on battery life yet.
