Get instant and reliable digital depth readings with the Humminbird HDR 650 In-Dash Digital Depth Sounder. Designed to work without a hitch even in the harshest marine environment, the sounder is a trouble-free solution. Coming with two components, the depth sounder includes a sonar unit and a transducer. The sonar unit contains the transmitter and receiver, along with the display and user controls.
Sonar technology works on sound waves. The Humminbird HDR 650 Digital Depth Sounder determines the depth directly below the transducer using sonar technology. The included transducer works perfectly with the sounder and converts electrical energy transmitted by the sounder into sound waves or mechanical pulses. Sound waves reflected by the seabed are also received and converted back to electric signals by the transducer.
A sound wave signal is sent by the sounder and the distance is determined by measuring the time between the transmission and reception. Received sonar signals are then converted to a digital depth that is displayed on the sonar unit screen. The reading gets updated constantly while you travel through the lake or ocean. Using a backlit display helps with visibility during both day and night situations.
All user functions are controlled using a three button keypad. Powering on your Humminbird HDR 650 In-Dash Depth Sounder is pretty simple. Just turn the power source on or off to control when the sounder operates. It is also very easy to operate the HDR-650 Depth Sounder. Just press the Menu key till you reach the desired function, and select a value using the Up or Down arrow keys. Wait 5 seconds and the unit saves your selection and returns to normal operation. Always be sure of your position and how deep the waters are, with the Humminbird In-Dash Digital Depth Sounder.
