"Vemco VR2 Receiver"@en . . "TOOL1164" . "An acoustic receiver comprising hydrophone, receiver, ID detector, data logging memory and battery housed within a submersible corrosion-resistant case. It is used to remotely retrieve ID numbers and time stamps from VEMCO coded transmitter tags deployed on marine fauna travelling within the VR2's receiver range. The VR2 is ideal for use in river monitoring or freshwater lake studies, as well as large tracking operations in oceanic systems. It features a Smart LED (light emitting diode), two megabytes of data storage (approx. 300000 detections), a resume study feature, and a replaceable battery (single Lithium cell). Detections are stored in the VR2's memory for later retrieval using a VR PC interface and a PC computer running VUEsoftware. The VR2 is now discontinued and has been replaced by the Vemco VR2W receivers." . .
