I have both a Leica 1200 Scanmaster and the new Swarovski Laserguide 1500.
The Leica has fair optics in comparison, but the Swarovski is in my opinion far better optically.
The Leica I have ranged out to 1170 yds on game.
The Leica has a better display then the Swarovski as it is far easier to see in all light conditions.
To date the best I have ranged with the Swarovski is 1320 yds on a cow and 1765 yds on a truck.
Both are well worth the money,
KK
