This is one of our smallest and lightest glue-on tracking transmitters. Please note, for the lightest variant of this transmitter, you will need to select the "solder external wires" model, this activation method does not require an internal reed switch for your transmitter to operate, doing so saves you weight for studies involving extremely small species.

Just like traditional VHF telemetry & Tracking Transmitters, this transmitter emits a steady radio pulse for the entirety of it's lifespan, VHF tracking transmitters can be picked up by receivers from extremely far distances using VHF receivers you may already be using in the field, for even greater RF output and signal strength, 3v models will always out-perform the 1.5v variants (the trade-off is size and mass). Specific frequencies are noted on your purchased transmitter or provided with your order.
