Raymarine LifeTag is your personal wireless man-overboard system. Utilizing the very latest in radio frequency broadcast technology, LifeTag monitors up to 16 tagged crew members. Each LifeTag pendant broadcasts a unique identification code back to the base station to inform that the wearer is on-board. In the event of man overboard, the link between the victim's pendant and the LifeTag base station is broken, and the alarm is raised automatically on-board. The lightweight LifeTag pendant can be easily attached to your life jacket, PFD, safety harness, or belt. The pendant's lightweight and compact size make it unobtrusive and easy to wear. LifeTag's state-of-the-art electronics ensure a long battery life in excess of 200 hours. LifeTag can trigger the automatic man-overboard in Raymarine SeaTalk compatible chartplotters, radars, and instruments. LifeTag system includes 2 LifeTag wireless pendants, LifeTag base station, batteries, straps, alarm module, power cable, and handbook. Extra individual LifeTag wireless pendant with CR2 3V lithium battery is also available. Add to any LifeTag Wireless MOB system to protect additional crew members (up to 16 total). Two-year warranty.
