The Garmin B164 is a 1 kW bronze thru-hull transducer engineered for coastal and offshore applications where hull geometry matters. Its 20° tilted element keeps the sonar beam oriented straight down on hulls with deadrise angles between 16° and 24°, eliminating the need for a separate fairing block. Dual-frequency operation at 50 kHz and 200 kHz provides solid depth coverage and water temperature readings across a broad range of conditions.
