Garmin, Thru-Hulls & Seacocks
$664.29

Dual frequency (50/200kHz) transducer is specially designed to provide a vertical beam without a fairing block. Inside the housing, the ceramic element is tilted to provide built-in deadrise compensation. The resulting vertical beam provides excellent echo returns for more accurate depth readings. The nearly flush housing minimizes drag with only 3/16" extending outside of the hull. Includes a built-in temp sensor and handles up to 600 watts (RMS) power. Includes 39' cable.
