That's what I've done also I turned mine down to 50' and put sharpness on high then if I see something I whip a bouy out and swing by it again someday I will get a unit that I can link with it on the front but for now I have a 597 di up there and when I find what I'm looking for w it I set a waypoint on it too. It defiantly takes a lil learning. Hope to get a lot more time to play w it this sat
