Powerfully simple, the 4" echo 151dv includes an all-in-one transducer that combines advanced HD-ID 77/200 kHz with Garmin DownVu scanning sonar. Effective fishing requires that you know what's under your boat. This unit will give you a near photographic quality view of both fish and structure.
View DownV and traditional sonar on the 8-level gray scale display and experience excellent target separation and bottom tracking with 1,600 W peak-to-peak power. Narrow-to-wide viewing cone angles give you a big picture well beyond the sides of your boat, from shallow water down to 1,600 feet maximum. Includes quick-release tilt/swivel mount and transom/trolling motor transducer mount kits.
