These cylindrically shaped units are designed tail mount attachment on raptors and other large birds, or configured for collar attachment to birds (ex. quail to capercaillie), herps (ex, lizards), or small mammals (ex. squirrels, primates, or large bats).

Frequency Range: 138 to 235 MHz.
Pulse Width (standard): 24 milliseconds (ms). Available from 18-32ms.
Pulse Rate (standard): 40 pulses per minute (ppm). Available from 5-120ppm.
Housing: The battery and transmitter are encapsulated in an inert waterproof epoxy.
Attachment: A number of mounting options are available (see photos above). Glue on (no mounting setup), an elastic or Dacron line neckloop, tubes for the passage of harness material, or a wire loop for attachment to a necklace. A collar setup will add 0.5-1.0g to the final weight.
Antenna: Stranded stainless steel cable covered with a black nylon coating. One or two layers of shrinkable tubing reinforce the antenna at its base.
Activation: Holding a magnet next to the unit starts the transmitter. Passing it over again stops it.
Options
Note: Multiple sensors can be added to a single unit.
Mortality (suffix “M”): After a preset period (1 to 23 hours) of no movement, the pulse rate changes (to an increased rate OR a double pulse) to indicate mortality. After the mortality mode has been triggered, any motion resets the transmitter to the normal pulse rate. Locking mortality is also available.
Activity (suffix “A”):After a preset motion sensitivity or angle has been reached, the pulse rate will change (to an increased rate OR a double pulse) to indicate activity.
Temperature (suffix “T”): An increase or decrease in temperature results in a corresponding increase or decrease in pulse rate. The high and low temperature limits are set by the user (0-50C), as is the pulse rate (5-120ppm) at each extreme. Each transmitter is supplied with a plotted calibration curve.
Duty Cycling (suffix “D”): To conserve battery power and extend the lifespan, the transmitter can be programmed to enter low-power mode each day (from 1-23 hours). During this low-power mode, the unit can be silent (0ppm) or programmed to pulse at a greatly reduced rate (4, 6, or 8ppm).
