Most boat owners only think about their bilge pump when they hear it running.

The problem is that if you’re not on board, you never hear it.

Your boat could be quietly taking on water for days or even weeks while the bilge pump works harder and harder to keep it afloat.

By the time someone notices the problem, the batteries may be flat, the pump may have failed, or the vessel may already be flooded.

A Bilge Pump Monitor changes that.

The Trek Bilge Pump Operations Counter continuously monitors every time your electric bilge pump starts.

Unlike current sensors that require cutting wiring, the Trek sensor is completely non-contact.

It simply attaches to the bilge pump or its cable and detects the tiny electromagnetic field produced whenever the motor runs. It works with 12V, 24V and 48V electric bilge pumps.

You can see:

• Number of pump operations
• Total pump running time
• Overall vessel status
• Battery condition

If the pump suddenly begins operating far more often than normal, you know something needs investigating before it becomes an emergency.
