| Definition | The VR2AR is a submersible acoustic receiver, combining an acoustic release with a VR2Tx (a VR2W receiver with a built in V16-like transmitter). It is used with Vemco coded transmitter tags placed on marine fauna to track their movements or behaviour. These detections are then received and stored by Vemco receivers, whose content are monitored by the VR2AR. The unit allows remote communication with all Vemco 69 kHz receivers while still deployed, and it can be retrieved via the built-in acoustic release. Deployed receivers can also be retrieved via the VR2AR, and their status monitored on demand via communication with a surface VR100 tracking receiver and transponding hydrophone. Receiver health, tilt angle, range, temperature, battery life and memory can be monitored in this way. The total number of detections stored by different receivers and specific transmitter tag IDs can also be monitored. An optional flotation collar is available to assist in location and retrieval of the VR2AR. It attaches below the receiver hydrophone ensuring there are no shadowing effects on the receiver. It has a maximum depth rating of 500m, battery life of approximately 14 months and 16 MB internal storage. | ||
