NASA Marine MOBI Man Overboard System

Posted / 29th January 2018

NASA Marine MOBI Man Overboard System c/w 3 MOB Fobs & Batteries

The ideal compact and affordable Man Overboard system for vessels with up to eight crew.  This system will be on display on stand 9 at the Skipper Expo Show in Galway on 2-3rd March 2018.

The Nasa MOBi is a state of the art, fail-safe transponder man overboard system. It consists of a base unit and up to eight active transponders for crew or valuable equipment.

In operation the base station sequentially interrogates each transponder which then broadcasts its presence. In the event of a crew member falling overboard the drop in signal level is detected by the base unit which sounds a high intensity audible alarm.

To aid identification of the missing crew member the base station continually displays the names of all the crew currently logged on, the signal levels of their transponder fob and their current status.

Three AAA cells power each transponder for several weeks of continuous use. Should the base station be turned off the transponders will go to sleep with a life of several years.

Man overbaord fobs, small in size, up to a max of eight can be used
Transponder fobs to alert your location.


The display comes with three fobs, additional single fobs can be purchased or a pack of five fobs.   Contact us to order your MOB system today: Tel  +353 (0) 74 9731180.
