Buddy Watcher Master Edition - Single Unit w/Small Strap - Sold as a pair
The Buddy Watcher is an underwater signaling device utilizing ultrasound frequencies to set off a vibrating and LED light alert on a corresponding paired unit. This makes silent communication between buddies possible and quite easy. The Buddy Watcher also has the ingenious ability to pair up to several units, if divers so choose, if they want to stay in touch with a dive group.
The Buddy Watcher now has an extra added function making it Master Unit capable. The dive guide, instructor, or dive master can alert all the divers in the group at the same time. Conversely, all the divers in the group can alert the guide. With the Master capability enabled, the diver still has the ability to alert just their buddy.
