The underwater acoustic beacon features a 37.5 kHz operating frequency and can function at depths up to 20,000 feet. It has a minimum useful life of six years and operates for at least 30 days. Constructed from durable aluminum, it is powered by a replaceable lithium battery and is suitable for fresh or saltwater use.
The DK140 operates at 37.5 kHz and functions from surface to depths of 20,000 feet (6096 meters). It has a 6-year battery life in storage before replacement is needed. Upon immersion, it emits a 160.5 dB acoustic pulse for effective search and recovery. The pulse repetition rate meets or exceeds general performance requirements for non-certified applications.
