McMurdo Smartfind S20 Personal AIS Beacon

The Smartfind S20 Personal AIS Beacon from McMurdo is a personal AIS device worn on a lifejacket and activated by sliding off the safety tab and lifting an arming cap to deploy the antenna. The compact, lightweight unit sends alert messages, GPS position and a special identity code directly to AIS receivers within approximately a four mile radius. A flashing LED light aids location at night.

A unique, built-in, high precision GPS receiver - which updates every 60 seconds – assures accuracy of the data transmitted from the S20. With precise location, distance and bearing data, fellow crew members (and nearby AIS-enabled receivers) receive all the information they need to locate the position of the person in difficulty and to enable a speedy recovery. The S20 will transmit continuously for up to 24 hours and has a seven year battery storage life. It is made of ultra durable ABS and is waterproof to five meters.
