Bud, I don't remember which rifle that would have been but the rangefinder was Lasertech's 1,500 yard model. Since then I have bought a Leica Locator-Plus which is a 4,000 yard model which includes 7 power binoculars. Now, no one needs 4,000 yards but this one is about as good as you can get at distinguishing deer-sized targets among brushy distractions out at the 1,000 plus figure. It also will automatically figure parallel distances to negate incline errors. That is really a nice feature.
