Garmin 010-11010-20 50/200KHZ B164 20DEG Depth/Temp 8-Pin

Airmar's B164 8-pin bronze thru-hull mount transducer with a 20° tilt is a great choice. It can accurately provide depth and temperature information. Operating at 50 or 200 kHz, it fits well on a 16 - 24° deadrise angle.

Using this transducer is easy. First, mount it on your boat's hull with a 16 - 24° deadrise angle. Make sure it's firmly in place. Once installed, connect it to your compatible device. It will then start showing you depth and temperature data. When using, avoid hitting it against hard objects. For maintenance, clean it regularly with a soft cloth to keep it working well. Don't expose it to extreme temperatures for a long time as this may affect its performance.
