The T3 Transponder for Haglof Instruments makes it possible to take height and circular measures with ease. Place it on a tree or a pole using the pin (included) and it measures height. Use it with the 360-degree adapter and the monopod staff and it quickly measures in full circle in sample plot work.
The Haglof T3 Transponder can be operated as a reflector or a visible target point when used with the laser rangefinder. It is compatible with Haglof instruments such as Vertex IV, DP DME, DME, and VL Vertex Laser.
This Haglof accessory has a simple construction in a bright, visible color. It is water-resistant and rugged. The T3 uses one AA battery and has a maximum consumption of 9mW.
