Your boats bilge is monitored by one or more float switches connected to Trek Transponder which will alert you by SMS should water level become too high. Unless you are on your boat you don’t know how much water is in the bilge. Save yourself expensive water damage costs by finding out early with a Trek Transponder SMS  if there is. Flooring, carpets and under floor wiring and plumbing are expensive if ruined. Dont let that happen.





Trek Transponder can monitor up to four battery banks of either 12V or 24V type. If any become low voltage Trek Transponder will alert you by SMS. Batteries are easily damaged if they go too flat, and are expensive to replace. And your bilge pumps dont work.  Find out if theres a problem with your batteries by fast SMS from Trek Transponder before it costs you. Trek Transponder can also monitor AC shore power instantly if it fails.





The location of your boat is monitored by Trek Transponders built in GPS. If your boat moves away from its allowed area this may mean a failed mooring or an attempt at theft. When cruising Trek Transponder can tell you that your boat is still where you anchored and hasnt dragged. Trek Transponder will SMS you if your boat moves outside its area. You can attend to the problem quickly before disaster. You could save yourself the expense and difficuilty of retrieving your boat aground or drama and expense of your boat hitting another boat.





Trek Transponder is the only Marine Transponder to monitor boat pitch and roll and vessel list (angle in the water). A boat slowly filling with water may be in big trouble before the bilge float switch is activated. By monitoring your boats angle in the water and pitch and roll you wont be caught out. You can fix the problem before your boat goes down or is badly damaged. Pitch and roll monitoring is essential for boats kept on moorings that are not sheltered. Model S100A and SM100A alert you to your boats excessive pitch and roll sea motion – that can break a mooring.






Depending on model a temperature measurement input is available. Measurement range is -25 Deg C to 120 Deg C. This can be used for monitoring temperature of fridges and freezers. Fridge or freezer  failure can cause substantial and expensive losses of food or bait. It can also be used for monitoring engine coolant temperature. (An optional Trek Transponder expander increases number of temperature measurement inputs to eight).
