Tilted Element™ B164 Bronze Flush Thru-hull Mount Transducer with 30′ Cable by Raymarine®, Measures: Depth/Temperature. Frequency: 50/200kHz. Max Power: 1000W. Accommodates Deadrise: 16° – 24°. Tilt: 20°. With 3 internal ceramics the B164 provides the increased performance of a 1kW transducer, while maintaining the benefits of a low-profile, deadrise compensated housing. Given their flush design, low-profile transducers may be more easily subjected to surface aeration at higher speeds.
