If the chance of losing one of your fishing buddies overboard has you worried, let LifeTag ($685) calm your fears. Manufactured by Raymarine, LifeTag is a wireless system that provides a locator beacon to each crew member. Should one of your passengers take the plunge, the beacon's signal begins to weaken as it goes out of range or is immersed in salt water, setting off an audible alarm on the onboard receiver. You can also connect LifeTag to your Raymarine navigation system, and the man-overboard function on the GPS will automatically trip once the alarm goes off.
