Biotracker VHF Receiver

  • Product Type Icon Receiver

Sophisticated, lightweight, rainproof radio receiver

The Biotracker was designed by fieldworkers familiar with radio-tracking, who understood the need for a small lightweight receiver when out for long days, but still wanted sophisticated features and a long battery life.

Moreover, we thought about where the controls needed to be, and where the antenna connection should be, so that it was easy to use.

It’s now been manufactured for over 15 years, and is still as popular as when it first emerged.


  • Flexible power options – rechargeable or primary cell. The receiver can also be powered from external power supplies (e.g. car cigarette lighter).
  • Product Features

    • Internal speaker & headphones socket
    • LCD Back-light – suitable for night tracking
    • Dual gain control (keypad buttons and knob)
    • Bar chart and numerical display of signal strength
  • Product Applications

    A Biotracker is the best receiver when manually tracking traditional radio-tags and you want a small light receiver with excellent functionality. Requires a hand-held antenna, and VHF tags such as our small PicoPip transmitters or longer-lasting Core and TW tags.

    The Biotracker can also be used to locate any GPS tags with VHF beacons.
