Not like you to stir up trouble Jim!
As you have no doubt learned over the last few years I like to think of myself as somewhat of a "traditionalist", I like to stalk. To my mind, and in the broadest terms, there are only two distances that matter: "close enough" and "too far". What numbers are applied to each are a matter for the individual stalker, but each should be confident enough in their own ability (both shooting and estimating range) to know their own limits. A true stalker will also readily admit to being fallible. I have shot red deer in excess of 300yds when required, and I have missed roe deer at 40yds, no technology in the world will compensate for the fact that I am human and every so often I make an a**e of it...
I believe that range-finders do have their uses, and to my mind that is primarily as a training tool. Use one whilst out with the dog. Guess the range to a tree then measure it. The same with a rock, or a fence post, or a rambler, or a patch of whin, or a bench. Build up a mental library over all types of terrain and in all weathers. But whatever else, do not come to rely on them as a substitute for your eye (or the eye of an experienced stalker). There will come a day when you drop it on the hill, or the battery goes flat or the electronics decide to give up the ghost.
For me it is not technology that causes the problem, it is the over-reliance on technology that we see in all parts of stalking nowadays; from the latest rifle made of materials that weren't on the periodic table ten years ago in the latest "must-have-deadly-accurate-flat-shooting-highpower-ultra-accurate-best-calibre-ever", to thermal-imagers taking the place of a pair of binoculars and the ability to spot a beast. They can all be valuable aids, but they should not become substitutes for experience and learned-skill / ability. Increasingly nowadays they are being used for this purpose though, a short-cut to putting in the time.
Having said all that, I will (somewhat hypocritically) consider replacing my current bino's with a RF pair when the time comes. Having the inbuilt, and readily to hand, ability to confirm an estimated range is probably a valuable check in welfare terms. And, as mentioned above, we all occasionally make mistakes...
