Product Overview

Airmar P66 TRIDUCER Depth, Speed, and Temperature Sensor

The Airmar P66 TRIDUCER combines depth, speed, and temperature functions in a single transom mount housing, making it ideal for boat owners and enthusiasts. Designed for optimal performance, this sensor operates at dual frequencies of 50 kHz and 200 kHz, allowing for precise readings in various water conditions.

The sensor features a hydrodynamic design that minimizes turbulence for improved accuracy at high speeds, suitable for boats up to 8 m (25') in length. With a robust plastic release bracket and a recessed water-flow channel, this sensor is built to withstand the rigors of marine environments.

Expert Overview

The Airmar P66 TRIDUCER is a transom-mount sensor designed to provide integrated depth, speed, and temperature data. This unit is suitable for marine applications requiring multi-function sensing from a single device. Operating at dual frequencies of 50 kHz and 200 kHz, it offers depth performance up to 366 m at low frequency and 206 m at high frequency. The 600 W power rating supports reliable data acquisition. Its hydrodynamic design aims to reduce turbulence, contributing to accuracy, particularly for boats up to 8 m (25') in length. The durable plastic housing and release bracket are engineered for marine environments. The 31-657-1-02 part number indicates a specific configuration with a 10-Pin Furuno connector, simplifying integration for compatible systems. This sensor addresses the need for consolidated data input in marine navigation and monitoring setups.
