Simply connect the S100A to your boats batteries, add a bilge float switch, plug in the free prepaid Aldi SIM and this unit is immediately monitoring your boat and can send alarms to your phone and up to 5 others.

You can also add a PIR or door switches to monitor security, temperature sensor for fridge and any compatible siren/flashing light.

Early warning of problems gives you the opportunity to solve those problems before they become expensive, disasters or insurance claims.

Trek Transponder S100A has two output relays, one is automatic and triggered by security inputs and is intended for sirens or flashing lights. The second is manually controllable by SMS from your phone and can be used for pumps, deck lights and many applications.

Trek Transponder S100A operates from 12V or 24V and draws only 0.04A so is easy to install on most boats. Power use is so low its no problem for boats on moorings. No special SIM or Data SIM is required, only a simple phone SIM.

Trek Transponder is Australian Made and has a 2-year warranty.
