27 inch walleye less than 24 hr out of the box 2/2


The unit was so clear we were able to see negative fish laying in the mud, which provided us with the intel to stay put. To make a long story short within 24 hours of purchasing this unit, the first-time ice angler, caught a 27-inch 8-pound walleye, 14.5-inch crappie and 12.5-inch perch.

We had no problem finding our micro tungsten jigs in 28 feet of water.

The battery life was very impressive, and you will not have to worry about charging your flasher during a weekend over night trip.

For those of you who fish in a group, I was using a 2-man eskimo, and we had a velixar Fl 30 and the Marcum running simultaneously and there was no interference at all.

I can not comment on the durability due to only taking the unit out two other times post purchase, but the walk out was 4 degrees snowing, bitter cold and the unit fired right up.

Tight Lines,
