Kannad Marine recently launched the SafeLink R10 SRS (Survivor Recovery System).

The SafeLink R10 SRS is a personal AIS (Automatic Identification System) device designed to be worn by individuals and activated to assist with recovery in a man overboard situation.
Worn on a lifejacket and activated by sliding off the safety tab and lifting an arming cap to deploy the antenna, this product sends structured alert messages, GPS position and a special identity code directly to AIS receivers within (approximately) a four mile radius.
The company says that the accuracy of data is guaranteed thanks to the unique inbuilt high precision GPS receiver which updates every 60 seconds. With precise location, bearing and range data given, fellow crew members or nearby sailors’ AIS enabled receivers have all the information they need to locate the position of the man overboard and carry out a speedy recovery, greatly increasing chances of rescue.
The R10 SRS can also be professionally fitted to a lifejacket so that it automatically activates whenever the lifejacket is inflated. A flashing LED light aids location at night. The R10 SRS is guaranteed to transmit continuously for 24 hours and has a seven year battery storage life. It is made of ultra durable ABS, and is waterproof to 5m.
The dimensions are 0.5″ x 1.8″ x 4.7″ and the device weighs 4.23oz. It will be available in the second quarter of this year.
