So i'm looking to buy a Helix 5 DI for my bow mounted trolling motor. I'd like to be able to use "jigging mode" when targeting Lakers, white perch, etc. That paired with spot lock will be phenomenal I think. I currently have a Helix 7 SI G2 GPS and I have done all the software updates and that unit doesn't have jigging mode? Does anyone know if/what model of Helix 5's have jigging mode enabled? If the price is right I prefer an Helix 5 with GPS, but not a deal breaker if it doesn't. thanks!
