Hey guys, I'm brand new to the board and I'm not in your area. I'm in New England (yeah sorry - home of the GOAT - please don't hate, I grew up watching Plunket, Grogan, Eason,etc. We did our time). Anyway, I stumbled upon this message board while looking for tips on using my Humminbird 597 on the ice. I found a lot of good info here. However, I am looking to see how exactly you guys that use this device on the ice set it up for optimum ice fishing performance as well as maximum battery conservation. I assume that if I turn of GPS and DI it will allow the battery to last longer. I simply don't know how to turn those features off. Any tips for this? Any help is appreciated! Go PACK Go! Go Bears! Go Lions, Go Vikings!
