“Now we have a mobile unit to find structure and fish”

Dave Kyle
Situation: Uses rented boats for bass fishing and needs a versatile, mobile depth finder
“On the rented boats you just couldn’t take a depth finder, you couldn’t see the structure you were floating over. Now we have a mobile unit to use and find that structure, target the fish we’re after and have a successful day out on the water. The mapping helps a lot. Maybe you might have missed something while you’re fishing, but you can study that later and be quicker to the structure.”
