Know exactly how deep the water below your boat is, and help in the avoidance of underwater perils, with the HDR 650 In-Dash Digital Depth Sounder from Humminbird. The single beam sonar uses an included transom mount transducer featuring 20° of coverage at 200 kHz to accurately read depths to 600'. Beyond reading depth, you can also have the HDR 650 alert you to predetermined depths via its programmable alarms feature.
The unit features a 1.25" backlit LCD screen, and is designed to install easily into your boat's dash using simple hand tools. Simply find a location with good visibility, and drill a 2-1/8" hole if a suitable gauge hole doesn't already exist. Easy to follow directions are included to help ensure a neat installation
