Self-Contained Submersible LED Flasher
XMF-11K LED Flasher with remote head

The XMF-11k is an independently powered, self-contained surface flasher that is fully submersible up to 11,000m (36,089 ft.). The super-bright LED provides unparalleled visibility in even the worst conditions and the reliability provided by our solid state surface sensor is a significant improvement over mechanical methods. The XMF-11k features microprocessor controlled, ultra-bright LED available in multiple colour options. The XMF-11k has a long lasting operational life of and features multiple activation options.

The XMF-11k is intended for locating and recovering high value, free drifting assets at sea. After being activated, the XMF-11k is submerged, where it enters an Underwater Mode. Here, it monitors water conductivity between the top disk and the bulkhead for up to 2 years. The LED will not flash while the XMF-11k is submerged.

Once it reaches the surface, the XMF-11k will begin to flash. If the daylight off, or tilt options are enabled, the device will not flash during daytime, and/or it is oriented upside down. The XMF-11k will continue to flash until it is manually turned off, the battery pack drops below the minimum voltage requirement of 7V, the XMF-11k is re-submerged, or if the daylight off, and/or tilt option prohibits.
