That was 2 other features about the 1500 was it runs off a 9v battery (best would be AA's but 9v not bad either) and it has 7x optical. Also, it has a bullseye mode that ranges the nearest reflection, and a brush feature that ranges the farthest object (like ranging a deer through some heavy brush). It also has the normal ranging as well. Oh, and a backlight is good for dawn or dusk, something most others don't have (but the Leica has the red LED so don't need a light).
