I have a Horus Vision ASLI for sale. Unit is in very good to excellent condition.....the Picatinny adapter bracket has a small nick from a screw that was too close to it when installed. Here is a description from the manufacturer:
Slope and cant Level Together in One Unit
The Horus Vision ASLI gives the long distance shooter a slope indicator and cant indicator in a single, precision engineered, hermetically sealed unit so you don't have to hang multiple gauges off your rifle like ornaments. It's reversible and can sit on either side of the scope, accommodating both right and left-handed shooters. The ASLI eliminates guesswork in uphill and downhill shots. To find the true horizontal distance, simply multiply the range to the target by the cosine value shown on the slope indicator. For long-range shots, the cant indicator is invaluable for keeping your bullet flight true to your sighted aim.
The unit that I have for sale has the Picatinny adapter. I am selling it for $55.00 delivered in CONUS by USPS Priority mail. Payment by PayPal, MO or personal check. Please deal by email. Thanks for looking.
