2. Setup and Installation
2.1 DepthTrax 2B Installation
The DepthTrax 2B comes with a dual-mount transducer that can be either transom-mounted or glued inside most boat hulls. Ensure the mounting location provides a clear path for the sonar signal and is free from turbulence.
- Transom Mount: Secure the transducer to the transom using the provided bracket and hardware. Ensure it is submerged and angled correctly for optimal performance at various speeds.
- In-Hull Mount: For fiberglass hulls, the transducer can be glued directly to the inside of the hull using a suitable marine epoxy. This method requires no drilling through the hull.
Route the transducer cable to the display unit, ensuring it is protected from abrasion and interference. Connect the waterproof plug to the back of the DepthTrax 2B display.

2.2 FIAMM 5190512 Marine Horn Installation
Select a mounting location for the horn that allows for clear sound projection and protects the horn from direct water spray. The horn is designed to be surface-mounted and includes a stainless steel grill for protection and aesthetics.
- Mount the horn securely using appropriate marine-grade fasteners.
- Connect the horn to your boat's 12V DC electrical system, ensuring proper fusing and wiring according to ABYC and Coast Guard standards.
