After much reading, studying, and worrying my new Zeiss PRF has arrived. I am going to work this thing to death trying to see what it will and won't do. I will be testing and posting on this thread till I finally run out of ideas of what to try next. First issue is the case. It is not easy to slide the unit into and out of the case. The seams get in the way. If anyone has the leica prf, do you case it eye piece up or down. Neither is very smooth. Little thing, but, I like my holsters to fit the gun they are holding. First rangings: High noon ranged instantly on a dog at 638, a water tower at 1445 (yep, beyond the advertised 1300). Microwave towers at 545, 775, 438, and 650. Lots of towers to laze. Ok hits the big stuff. To the resovoir. Ranged several ducks and geese at 175 through 350 on the water. I was on a bank twenty feet above the water. Ranged a beaver lodge at 465. Range a dog at 635. Problem, skipped off the water at 450 to read the bank at 625 when I tried to hit a swimming duck. Ok more odd tests. Lazed a white dog at midnight through a steady light rain that was passing at 93 yards by ambiant light (moon + white dog) It didn't seem to be bothered by the light rain but very short range. I can laze through light brush to a solid lock if I make sure there is no real big piece in the aiming circle. It let me bypass the branches to lock on a squirrel at 165 yards. I checked this by moving the retical to the trunk and to other branches. I got a different range lock each time and they made sense, so this is pretty slick. It seems to ignore the scatter and still lock on the target. I cannot lock on a stainless steel 12"x 14" metal grid at even 50 yards. I believe the same program that ignores the light brush, ignores the 3/4 inch metal grid. Scatter at close range is not a problem. I was 40 yards from a pair of 6" trees about 2 feet apart. I was able to center the retical at a target 380 yards beyond the pair and laze between them consistanly. When I shifted the aim to the trees, it locked both of them. Not mudh distance, but, it did not get confused between them and allowed me to pass between them. Anyway, with the exception of the case, so far I am pretty pleased with the PRF. I will go for more fur this weekend. I really just want consistant ranging in the 500 - 1000 regardless of the time of day. I am going to try working from the prone as well and see what can be done when trying to range 14" targets against ground clutter. I know this was long, but, I am 60 and this is my first laser. thanks rc It will NOT lock on anything too close. Couldn't help it, I had to try.
