All Trek Transponder models are designed and made in Australia, ruggedised IP67 and come with 2 year warranty.  Extensive technical support is available to help you get the best from your unit online and by phone.

Popular models are listed below.

The E100 model is a low cost unit suitable for small vessels, often on a mooring, and suits when a budget is tight.  It would typically monitor a battery, bilge and a single access point such as a hatch or storm board.

S100A and S100A-NFP often suit cruisers or yachts on a mooring with solar charging, two batteries, intruder sensors, location, pitch/roll and listing added to monitoring.  If your boat breaks off its mooring, bilge floods  or your batteries fail you will know.

SM100A and SM100A-NFP are fully featured adding monitoring for four battery banks – over and under charge, shore power and more extensive security monitoring, and are commonly used for bigger cruisers, yachts and commercial vessels on moorings or in berths. These two models also offer HD cameras.

All Trek Transponder models can connect to wireless sensors. However due to  unreliability caused by batteries regularly going flat, expense and lost time replacing them, and  environmental damage disposing of them we recommend wired sensors.

You will not find a marine monitoring system as fully featured as the Trek Transponder on the market today. If you want the best Remote Monitored Boat Alarm you can get, compare our features below:
