Description
The “In-Hull” Temperature Fix
If you use a shoot-through-hull transducer (epoxied inside your bilge), your fish finder reads the temperature of your fiberglass, not the lake. The Humminbird AS T Y Cable solves this by splitting your unit’s transducer port into two.
How it works:
Plug your In-Hull transducer into one side for Depth/Sonar. Plug a separate transom-mounted Temperature Sensor (TG W) or Speed Wheel (SW) into the other side. The cable merges the signals so your HELIX displays depth from the hull and accurate temperature from the water.
