Echonautics BT70MA600-12 is a top - notch low - profile thru hull CHIRP transducer. It can match your vessel's deadrise to a specific 12° angle, suitable for hull deadrise from 8° to 15°. This transducer is designed to minimize drag, allowing it to perform excellently at high speeds.
It can measure depth and temperature. With a CHIRP frequency range of 80 - 130kHz and 600 watts of RMS power, it has a maximum depth detection of 900ft. The beamwidth is 24° to 17° @3db. The transducer is made of bronze with a urethane acoustic window and an NTC temperature sensor. It comes with a 27ft cable and requires a 2.38 - inch hole diameter for installation.
Using your Echonautics BT70MA600 - 12 transducer is easy. First, find a suitable location on your vessel's hull where the deadrise angle is between 8° and 15°. Drill a 2.38 - inch hole for installation. Connect the 27 - foot cable to your compatible device. Once installed, turn on your device, and it will start measuring depth and temperature. When using at high speeds, you'll notice its low - drag design keeps it performing well. For maintenance, regularly check the cable for any signs of damage. If the acoustic window gets dirty, clean it gently with a soft cloth. Avoid using harsh chemicals on the bronze element to prevent corrosion. Keep it stored in a dry place when not in use to ensure its longevity.
