It seems to me to be faster and I can mark a stump with my lowrance and go right to it with the garmin I may have to look a little if I could afford to do it over again I would run 2 93sv and a lowrance GPS unit with a 5 inch screen that way I wouldn't have to split the screens also would like to add garmin is a hole lot easier to use wouldn't take for it. Another thing okie Bob has 2 touch 9s hooked up to antenna and I feel like its not as fast and as accurate as the gen 3 that's just my opinion and it could be just me
