Live, constant monitoring of DC faults from both positive and negative to earth / ground.

Get early indication of DC faults that have the potential to cause stray currents and electrolysis.

Ideal for detecting issues with faulty wiring, old wiring, damaged wiring in bilges etc.

Easy installation in any vessel, only 3 wires (battery positive, battery negative and a ground such as engine bed).

Can directly replace monitoring boxes that utilise a test switch and two lamps.


For the geeks among us the device will trigger if the resistance from the monitoring point to the positive or negative supply rails drops below roughly 2700ohm for a 24vdc system.

Full technical support will be given to help you install the product.
