Ditto Catshooter.
I'm on my 3rd laser, and I've actually had the opportunity to field test (in pdog towns) at least half a dozen other makes and models (including the much vaunted Leica 1200 & a really hi-$$ Swarvoski).
While almost every one I tested would pick up an elk-sized object out to as far as you'd ever dream of shooting, against pdogs and pdog mounds, reliable ranging stops at ~350 yards, regardless of model, or the amount you spent on it. Most will, of course, pick up a terrain feature (other than a mound) beyond that, but in pdog country, there often aren't any terrain features.
When I absolutely, positively have to range a pdog at long range, I break out the Swedish Army Mortar ranging periscope. It's an optical unit, and very cumbersome, but it'll accurately range anything you can see under any conditions out to 1700 yards.
The technology may be a century or so old, but when it comes to small targets at long distances, a civilian (and probably even military) laser won't begin to compare to a quality optical unit.

edit: 6mm06 - please don't take my "much vaunted Leica 1200" comment as directed at you. I didn't even notice that part of your reply before I posted mine. The Leica 1200 is indeed one of the best units out there, but, by personal experience, it's not noticibly better in the dogtowns than say a Bushnell 1500 Pinseeker. As you said, ~400 or less is about what you can expect.
The reason I posted this edit is because when I say this about the Leica unit, I usually get a bunch of irate comments from Leica owners stating I don't have a clue about what I'm saying. I notice most of these comments come from shooters that don't live within 1000 miles of the nearest pdog town.
Like I said...this wasn't directed at you. /ubbthreads/images/graemlins/wink.gif
