Quick ranging with silhouettes

To use the reticle, simply match the 
person or object being ranged to the 
silhouette that is closest in shape and read 
the indicated yardage. 

Note:

 The best 

accuracy will be obtained by bracing the 
arms or using a tripod mount.

The Viper HD tactical binocular comes with 
tethered objective lens covers plus a soft, 
waterproof piece that completely covers the 
eyepieces. For convenient use, simply snap the 
eyepiece cover around the neckstrap. 

Lens Covers

The Viper HD R/T’s protective case provides safe storage between viewing 
sessions. The carry strap is already attached to the case.

Securely attach your binocular to the binocular strap:

Neckstrap

1. Thread the end of the 
strap from the bottom 
up through the strap 
attachment loop.

3.  Adjust the overall 
length and pull the strap 
webbing tight so it is 
secure within the buckle.

2.  Hold the buckle and 
thread the end of the 
strap inside the buckle.

Note: 

Please 

do not

 thread a metal ring directly onto the strap attachment loop 

when attaching rings or clips for other after-market equipment. Instead, use nylon zip 
ties according to the manufacturer’s instructions.

28cm / 11”

50cm / 20”

44cm / 17”

Using silhouette widths—

The silhouettes used in the R/T reticle are based on 

an average 20-inch shoulder width and 11-inch head width. Take your range 
reading from the silhouette that most closely matches the size of the person.

Using silhouette heights—

Heights of the silhouette may also be used to 

quickly estimate range when comparing objects of known dimensions. For 
example, assuming a typical back-to-brisket dimension of 17 inches, a deer can 
be ranged using the 17-inch shoulder height on any of the silhouettes.
