The Garmin 160 Fish Finder has some big advantages over the competition. First, the exclusive See-Thru? technology allows the Fishfinder 160 to hear both weak and strong signals simultaneously, giving it tremendous dynamic range. The result is a display that is capable of showing strong fish returns even when fish are suspended inside structure and thermoclines. Second, Depth Controlled Gain (DCGTM) automatically adjusts fishfinder sensitivity according to depth, not echo intensity like other fishfinders. The result is a much more detailed and accurate picture of bottom structure.
On several occasions I’ve been on the water, paddling away in my kayak when my alarm will go off.
