[QUOTE="royinidaho, post: 1111707, member: 2011"] Did some quick and dirty googling... found the following: To be able to separate closely spaced targets in the tree crown, I need a device with a narrow laser beam. TruPulse200 is said to be such a rangefinder. In viewtopic.php?f=69&t=2861&p=11271&hilit=impulse200lr+trupulse#p11271 our shared friend Michael. W. Taylor wrote: Impulse200LR: 3) Wide laser beam. size of Nat Geo magazine at 1000 feet vs. deck of cards for Trupulse at same distance. You told me, beam divergence of TP200 is 3 m at distance of 1000 m (TP200X 2 x 4 m at 1000 m). These two statements do not match, please clear up! Me: Deck of cards size??? Nah....me thinks. Further digging: "Concerning the structure of the beam, there are now statements from the German distributor Breithaupt that refer to sources of LTI: Laser spot related to 100 m: TP200: ellipse lying, 42cm wide, 22cm high TP200X: ellipse, 20cm wide, 15cm high All TruPulse are equipped with infrared pulse lasers (I must correct my earlier statement)." Me: 1 meter = 1.093 613 298 3 yard 20 centimeter = 7.874 015 748 inch 15 centimeter = 5.905 511 811 inch Rounding up for shaky hands such as mine :) that's 8" wide and 6" high @ 100 Meters. Distance correction to yards: 1/1.093 613 298 3 = 0.91440000003153 Therefore: (that's math talk :roll eyes:)) again rounding 7" x 5.5" @ 100 yards or 70" x 55" @ 1K. This is for the 200X which seems pretty **** good to me. Or 1.94 yards by 1.53 yards. gun) All of this depends on my ability to calculate stuff properly. Which is questionable at times...

These folks are as persnickety as some of us..:D [url=http://www.ents-bbs.org/viewtopic.php?f=235&t=5517]Native Tree Society BBS • View topic - Testing TruPulse 200 X[/url] Manufacturers statement: The Laser Technology TruPulse 200x rangefinder achieves a maximum range of 1900 m (6233 ft) to non-reflective targets and 2500 m (8200 ft) to reflective targets.
