Leatherwood A.T.R. Uni-Dial Rifle Scopes
Pre-calibrated vertical (elevation) adjustment knobs or dials have been in use for about 100 years. The problem is that at the longer ranges, it is not practical to provide dials to cover a large variety of calibers. It is further compounded by other factors such as different bullets, barrel lengths, etc.
Although Leatherwood / Hi-Lux Camputer Model 1000 ART scope and Leatherwood / Hi-Lux 3-D mount have opened up whole new dimensions to the world of long range shooting, there are many precision long range shooters who still want to use a conventional style scope.
In the past there were two options for long range shooting: shoot a specific load or tape a chart of "computes" to the rifle stock. The Uni-Dial is designed to solve the problem.
By using a series of ten moveable indicators or flags, the shooter can set the range zero points himself. The dial is calibrated in minutes so that the Flags can be set according to the ballistic data. Once set, the flags are locked in place and the dial is operated in a conventional manner. The vertical dial has 1/2 minute click adjustment and windage dial has 1/4 minute clicks. Both adjustments have a stop to prevent the shooter from getting "lost" as to where his zero is. But both adjustments can be unlocked from the stops to permit zeroing.
The flags are numbered from 1 to 10. All allow the shooter to pre-program elevation and windage for up to 10 different ranges, or with different loads - and each can be locked in place and returned to within seconds. The total minutes of elevation change is about 60 MOA. There are about 20 minutes for initial zeroing. One full-turn for the change of elevation is 40 MOA. The Leatherwood / Hi-Lux Uni-Dial scopes now have all improved with a wider range of variable magnifications. The 3-12x, 4-16x, 6-24x and 7-30x in the Leatherwood / Hi-Lux A.T.R. Uni-Dial Series are featured with the handy Top-Angle Focus. All these models come with the enlarged erector/turret housing to make these the brightest 1" diameter scopes available today. They all come with the extended sunshade.
