Re: PLRF-10 & Multiple Target Function
My interpretation based on other lrf devices: If you are ranging an object but there are multiple reflections you can disregard the readings that appear to be wrong.
For instance, ranging an object through some trees may give a reading for the trees and the target you want at the same time. But the lrf doesn't know about the trees in the way. In traditional ranging it may give the reading of the biggest reflection (the trees) which is wrong. If you can get multiple readings and clearly know the trees are too close on one of the readings you can ignore it and use the other readings that are likely more correct.
Or consider the reverse. You are lasing an animal that is in front of a woodline. A traditional lrf may give a distance, but maybe the reflection it sees is the big one from the trees and not the animal? In that case your range is going to be way off. A smarter lrf will give multiple readings so the operator can make a decision which to accept and which to ignore. Instead of getting one reading which could be who knows what, the lrf is giving you all the data to make a choice.
In a practical sense I'll give you an example. Recently I was shooting at a steel target that was around 900 yards away. I lased it about six times and it showed 910 yards. But my eyeball said it was closer. I then milled it. The mills said it was 875 yards. That's a big difference for that range. But hey it's a laser and can't be wrong, right? So I dialed dope for 910...and shot over the target.
Actual range was 870. The laser was ranging a tree that was behind the actual target giving me the bad reading. If I had multiple readings that wouldn't have happened.
There's another lesson here, too. Milling is not dead yet! I always mil now and lase unknown distances as a cross check regardless of the laser brand.
