Re: leica 1200 or swarovski 8x30 laser guide?
I had the Leica and used it for many years, but eventually sold it for the Swaro...
I use a range finder hard... and expect it to service me well.
I use range finders from varmint hunting in PA to big game hunting in Alaska.
When you are trying to decide on which manufacturer, and are comparing the differences between the two, keep in mind that they are both class 1 lasers. These lasers are susceptible to bright sun light. Both will give you some degree of difficulty in ranging on bright sunny days on marginally reflective targets on flat ground...
Both the Leica and the Swaro will serve you well out to the 1K mark that you mentioned.
Do a search on here and read the many posts on the subject as that may help you make your final decision.
My personal opinion would be to buy, read... steal, the Swaro for $500.00 cool ones and you'll never regret it.
