Guys wondering about the relatively new FishHunter 3d directional before you buy one. This is my little review on using it this winter. I didn't use the 3d stuff as I think that is mostly valuable in open water. I was on ice mode with flasher style screen. Was impressed with the WiFi speed nearly real time. Only downside I felt was smallest depth range was 20 meters and I usually fish shallow. Check it out before you buy one of these portable castle devices. Pretty powerful little unit though. My phone usually would go dead before it in the cold.
