Fatboy Beacons, 1160 Series

Applied Acoustics Fatboy beacon

With their high source levels and options of narrow beam patterns, 1160 Series Fatboy beacons are ideal for deep water operations, noisy and acoustically challenging environments and applications requiring long operating ranges.

Fatboy transponders incorporate spread spectrum coding allowing extremely stable and reliable performance,  whilst maintaining a compatibility with almost all of the industry’s other standard USBL systems. Charging and programming are achieved using the 1082 Smart Switch, removing the necessity for mechanical switches on the beacon’s end cap.
