You never want to be surprised by the bottom. The Hawkeye digital depth sounder with auto-ranging and auto-sensitivity features is designed to give precise depth readings from 2.5 to 200 feet at speeds up to 63 mph. The D10D reacts instantly to changes in depth using a three-stage warning system. The 1.65" x 0.85" LCD reads depths in feet or meters, and uses SoftGlow backlighting for easy and reliable operation at night. The combination transducer included with the sounder can be either transom-mounted or glued in-hull. Includes interchangeable black and white bezels and face plates.
