• portable rugged computer (Getac)
Pen controlled IP67 weatherproof tablet PC with two simultaneous battery feeds to support battery replacement without powering down the computer.
• electric compass and laser pathfinder
TruePulse 360 R is a high-precision instrument for determining direction compared to magnetic north, among other functions. Its level of integration supports cooperation with other data capturing tools, including Getac, which makes it suitable for geoprocessing tasks and for capturing the data of surveyed entities automatically. Including a laser operated telemetry unit designed to measure distance, height and vertical angles. Its special features render it truly easy to use in forest stands where improper reflections and erroneous measurements can be filtered out with the help of its reflector prism.
