ASLI (Angle Slope Level Indicator)
Our new USA made ASLI device gives the long distance shooter a single, durable, light weight, precision engineered, and hermetically sealed unit. One gauge will provide both cant and angle of fire. The ASLI can be mounted on either side of the scope accommodating for right and left handed shooters as well as upside down depending on scope height. The easy to read angle indicator provides both degrees of angle and corresponding cosine.
For long range shots, the clear and bright ASLI is invaluable for keeping your rifle horizontal and true. Any minor deviation from being level will cause greater misses at greater distances. The device attaches directly to your scope via 34mm ring and also comes with a 30mm inserts to accommodate a smaller tube size. The unit may be painted to match your scope and doesn't require batteries.
The ASLI comes with a protective rubber cap, 34mm ring and 30mm inserts, Loctite, 7/64th hex key and instruction card.
The ASLI may be used along with ATragMX and our CATS targets. Simply enter the cosine value into the ATrag software to obtain your proper hold. Practice with our CATS targets to achieve perfect alignment between your scope and rifle.
To obtain the true horizontal distance to target when utilizing the ASLI:
Multiply the exact range to target by the cosine value given, hold wind for the original distance given and use your new elevation hold to hit any target at any range.
Distance to target: 475
cosine Value: .91
475 yards x .91= 432 yards
True horizontal distance: 432 yards
