Magnetically dampened to quickly halt oscillation for fast readings
Clear, large numbers for better visibility in low light
Readings in both vertical angle degrees and its corresponding cosine value
Versatile mounting for left, right, bubble up or upside down, and high angle grenade launching
Tested to withstand the repeated G-shock pounding of a 50cal BMG
Angle Slope Level Indicator
The ASLI gives the sophisticated marksman a slope indicator and cant indicator in one hermetically sealed unit. Its slope indicator eliminates guesswork in uphill and downhill shots by helping you find true level/ground distance: simply multiply the range to the target by the cosine value shown on the slope indicator. The cant indicator is invaluable in long-distance shooting: it helps keep bullet flight true to your sighted aim. The ASLI attaches directly to your scope, is reversible to accommodate left and right handed users, doesn't need batteries, and comes with a hard rubber cap. Fine-tune your aim with the ASLI.

I purchased this product and mounted it to my Nightforce scope on a .308. After shooting 20 to 30 rounds through my rifle the ASLI fell off the mount. I retightened it and took it out hunting. Again, it fell of with out even shooting. After tightening it again the screw was almost stripped. I contacted HORUS and they told me to contact the seller. I emailed the seller and they were unwilling to do anything. I then contacted Horus again and they said that their fail rate was very low, as they "test a handful of the ASLI's" when they get them from the manufacturer. Needless to say they wanted to sell me a new one. I wouldn't waste your money on this product. Spend the extra money and get one from Nightforce.
Nice device for target shooting use in conjunction with a shooter program that uses either the sine of the angle or the degree off horizontal. Longer shots out beyond 400 yards require exact calculations of angle if you are shooting up hill or down. This can be read with the off scope eye easily and adjustments made from the dial reading. Have it on a .308 and have had no problems with it loosening , I did put powdered rosin in the ring mount when I leveled it.
of very very good quality, good machine work went into making this item, it mounted well on my rifle and works fine
