The McMurdo Fastfind 210 buoyancy pack provides sufficient extra buoyancy to make the Fast Find float so it can easily be recovered if dropped into water. Each pack contains 1 yellow and 1 black floating pouch. The buoyancy pack is not designed to allow the Fast Find to float in an upright position, or to transmit a distress alert when floating in water. When in use, the Fast Find’s deployed antenna must be raised clear of the water by the user.
