I have been wanting a LIDAR gun for sometime. Found a couple on ebay. A Kustom Prolaser or a Stalker. The Stalker doesn't have a buy it now and I have a feeling the price will go up substantially, there are already 12 bids on it. The Prolaser has buy it now. Would the Prolaser still be relevent for testing purposes being that it is an old model. I read on here that they are actually harder to jam than others due to their good optics. Also I'm waiting to see if I get a V1 for Christmas, if not, I was going to get one with the money I have saved. Thoughts or opinions.
