Maritime Survivor Locating Device
Water-activated man overboard alert & GPS tracking

Crewsafe V100 Product Brochure

The Crewsafe V100 is a water-activated Maritime Survivor Locating Device (MSLD) that transmits accurate and regular GPS coordinates of a man overboard directly to rescuers via VHF marine radio.

This palm sized radio distress beacon can be integrated with a lifejacket or Personal Flotation Device (PFD), clipped to webbing or harness, or carried in a pocket and secured with a lanyard.

When its water sensors detect the wearer has gone overboard, the Crewsafe V100 automatically transmits a "Mayday, man overboard" distress alert using VHF DSC (Digital Selective Calling) [channel 70]. It can also be manually activated.

It quickly acquires a GPS lock, then transmits its GPS coordinates to all vessels in the vicinity, including the parent vessel, and to any onshore VHF receivers in range.

The distress alert is also broadcast on the VHF marine radio emergency channel 16 in a synthesized voice to maximize the number of people who can receive the alert and respond to the emergency. Alerting range is VHF line-of-sight: 2 to 10NM surface-to-surface and up to 40NM surface-to-air.

The radio distress messages are repeated at regular intervals for up to 12 hours to provide rescuers with the real-time location of the man overboard. The device also has a strobe light to assist with visual homing.

The only equipment needed to receive the distress alert is a VHF radio. All marine search and rescue authorities, SOLAS-compliant commercial vessels and a growing number of leisure craft are equipped with DSC-compatible VHF radios. This makes using the Crewsafe V100 for man overboard detection and in-water tracking one of the most effective, universally acceptable lifesaving devices available today.

Crewsafe V200 Submariner
Maritime Survivor Locating Device
Locate and rescue following submarine escape

Crewsafe V200 Product Brochure

Designed specifically for submariners, the Crewsafe V200 is worn with the SEIE suit to provide escaping submariners with the means to signal his position when he reaches the surface and therefore increase his chances of survival. The device transmits GPS position data via AIS, VHF DSC and VHF voice message to pinpoint the location (+/- 10m) of casualties following escape or abandonment.

One of the biggest risks of submarine escape is what happens when the escapees reach the surface. After evacuation or abandonment from a stricken submarine, survivors may be widely dispersed from their original escape/abandonment position and from each other.

Equipping submariners with the Crewsafe V200, which accurately transmits position data to incoming Search and Rescue forces, will greatly increase chances of recovery and survival.

The Crewsafe V200 is set to STANDBY prior to exiting the submarine which enables it to automatically activate and begin transmissions when the submariner reaches the surface.

On reaching the surface, Crewsafe V200 activates, acquires GPS and transmits distress and position data in multi-system alerts. The Crewsafe V200 repeats transmissions at regular intervals for a minimum of 48 hours, so that approaching rescue forces can detect individual transmission data from all casualties on the surface.
