This small and rugged handheld diver acoustic receiver with LCD display and signal strength meter can track and locate any acoustic pinger that operates between 5 to 80 kHz.
The ATT-400 transponder can operate underwater as a pinger or transponder. This underwater acoustic transponder is small and easy to deploy in depths of 1000m. When interrogated by the STI-350, DTI-300 or VADR series acoustic receivers, the ATT-400 provides range and bearing up to 750 meters away. The ATT-400 can also be programmed to operate as a free-running pinger. With a battery life of up to six months, this transponder is ideal for marking equipment and locations in poor visibility.
This underwater beacon is a cost effective free-running pinger used for marking equipment and underwater sites to depths of 1,200m. Using a single 9-volt battery, the ULB-350 can send a continuous acoustic signal for up to 60 days or on a programmed time delay for up to three months.
The PRS-275 is a diver pinger receiver that can be converted to surface pinger receiver using a separate directional hydrophone and user adjustable staff assembly. The system includes the DPR-275 diver pinger receiver, waterproof headset, adjustable staff assembly with directional hydrophone, cable assembly, and shipping container.
Acoustic release beacons are used to recover or lower equipment deployed under the sea, either in shallow or continental shelf waters.
