The new TruePulse Laser Rangefinder is a forester's dream come true. It is truly unique in that it measures closest and farthest distance. This allows you to shoot at a target and know if you hit some intermediate brush or twigs. The closest measurement is the intermediate obstruction and the farthest measurement is your target.

The TruePulse readings are viewed through the eyepiece. This saves time because you don't have to take the instrument away from your eye.  You can take multiple shots, one right after the other. This is especially helpful when sighting a tree to see if it is leaning. You just shoot the bole at a few different places to see if the horizontal distance changes appreciably. The distance should get slightly farther away as you look further up the bole because the tree diameter is less.

Here's some features of the new TruePulse Laser:

Accurate to plus or minus 1 foot (generally sub foot)
7X magnification to help you zoom in to specific targets
Measures both Slope & Horizontal Distance
Calculates Heights with a 2 shot height routine
Fits in a big shirt pocket
New Patented Optics

The Criterion RD1000 is the first patented electronic relascope/dendrometer that accurately measures tree diameters. Utilising the integrated tilt sensor you can collect diameter data at any point up the stem and also find the height at which a specific diameter is reached.

The Basal Area Factor (BAF) routine will show In and Out trees for a wide range of sampling factors - no need to buy any additional parts for your particular plots. "Borderline" tress are easily resolved by transmitting a distance from an LTI rangefinder into the RD1000's input serial port or manually enter in a distance via the keypad.

Are rough terrain and thick brush slowing you down? Eliminate positioning restrictions and obtain a direct read out of the diameter from any distance. The in-scope LED display offers variable brightness levels, making it easy to read under all lighting conditions. An included 2.4Χ magnifier can also be added for improved measurement resolution at greater distances.

The Criterion RD1000 includes a second output serial port for communicating to an external data collector.
