Re: LTI TruPoint 300

Actually, it will be the Disto S910.
How I was able to overcome the difficulties of measuring tall trees with a red laser instrument and get very accurate results, I described here:

Re: LTI TruPoint 300

Hallo Bob, Class 2 lasers operate in the visible light range. Does the TruPoint 300 emit a red measuring beam that you can see? The technical data seems familiar to me, it reminds me of the red laser of my Leica Disto D8. See here my report in the Bulletin of the Eastern Native Tree Society, Volume ...

Re: Nikon's New Monarch 7i VR Laser Rangefinder

What about the new Nikon Coolshot 80i VR?
It is equipped with Vibration Reduction and Inclinometer.

Re: ID this hickory

That's true, on the opposite side this deeply furrowed, partly reticulate structure of the bark is coined less. I consciously took the photo from the side of the trunk, where you can see this eye-catching structure most clearly. Here is another bitternut in Germany: http://www.monumentaltrees.com/en...

Re: Bulletin of ENTS, Volume 9, 2014, Winter and Spring

Thanks Don for this impressive bulletin!

A note to my article: The final three sentences (With the instrument preliminaries ...) seem to me somewhat strange and incongruous. Are they slipped into the text by mistake?

Re: Nikon 440 Clutter Test

Here is an other test with Nikon550:
- Pinhole 30 cm: up to ~200 m (reading through the hole: ~209 m).
Pinhole 30cm.jpg
It turned out that I had chosen the hole for the test plenty big. A smaller one with 15 cm to 20 cm would allow a better comparison with TruPulse.

Re: Testing TruPulse 200 X

The manual describes how to trigger the measurement by a remote cable with an open collector closure between pin 1 and pin 2 of the plug socket. I will use this feature to avoid shaking. This does not work. My dealer knows no advice. He waits for support from LTI.
