Thanks for the questions! This is a great topic for discussion. I figured I'd post a new thread and see if others have thoughts. Here is the original thread if anyone needs to reference it in the future: http://www.ents-bbs.org/viewtopic.php?f=111&t=6142
Nice work and great pictures! How did the Trupulse 200 and the Nikon 440 compare?
When shooting to a good target (tree trunk with no clutter), both of my units excel at being accurate to their displayed accuracy (Nikon 440: 1/2 yard, Trupulse 200: 1/10 yard). For the Nikon 440, I have some correction factors utilized at the clickover point that increase the accuracy beyond the displayed accuracy. When weak targets (small twig at the top of a tree or clutter) are present, it's a whole different ballgame. Here are my thoughts on the two types of weak targets commonly encountered:
Small Twig at the Top of a Tree
When shooting to a weak target, the Trupulse 200 will leave off the decimal. In this case, upon changing from yards to feet, the best displayed accuracy is 1 foot. The Nikon 440 gives consistent results (with displayed accuracy of 1/2 yard) whether I'm shooting to a good target or a weak target. When I'm measuring what I consider to be an important tree, I'll utilize both lasers as a way to double check my results. The Trupulse 200 is also extremely helpful when scouting for tall trees.
Shooting through Clutter
I am continually amazed at how well the Nikon 440 can penetrate very thick clutter, while the Trupulse 200 is rendered useless for finding distance in this situation. The Trupulse 200, however, is still extremely helpful for finding the angle in this situation.

I'll expose my bias, my current thinking is that the electronic clinometers (based on accelerometers detecting motion) outperform the Suunto/Brunton types...what do you guys think?
When they're held completely steady, I arrive at the same angles with the Trupulse 200 and the Suunto clinometer. However, I think that I'm more accurate with the Trupulse 200 when out in the field. I think I have a pretty steady hand, but I can't consistently get to a tenth of degree of accuracy with the mechanical device.
