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.

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...
Go here for a darn good read. These folks are as persnickety as some of us..

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. With an inclination accuracy of +/- 0.1°, the this rangefinder is accurate to +/- 4 cm (1.5 in) to typical targets and remains accurate within a foot (30 cm) at maximum range. The TruPulse 200x provides 7x power optics for optimum viewing with a 100 m (330 ft) in-scope field of view (at 915 m (3000 ft) away) and in-scope data display.
