Description

Designed by Vortex Optics, the Viper HD 4000 is a long-range, high-precision laser rangefinder made with premium materials and advanced technical solutions.
The housing is injection molded from a high-quality, impact-resistant polymer for superb durability and weather resistance. The weight of 280g and dimensions of 111x43mm make it a small and sleek piece of ranging equipment.
Viper HD operates in four targeting modes: normal mode, the first mode, the last mode, and ELR:

• “Normal Mode” is the standard mode that displays the result with the strongest range estimation.

• “First Mode” displays the closest distance when ranging. It is ideal for measuring the range to smaller objects in front of larger ones.

• “Last Mode” displays the farthest distance to the target. It is a prime choice for measuring range to target behind trees, bushes, or rocks.

• “ELR Mode” allows the ranging of smaller objects that reflect the laser beam insufficiently at the longest possible distance. A tripod or other external stabilization of the rangefinder may be required to acquire the appropriate range.

The additional HCD and LOS mode allows the proper ranging in uneven, hilly, or mountainous terrain.
The 25mm objective HD lens glass is layered in an ultra-hard, anti-scratch, and reflection ArmorTec® multi-coating. It secures the lenses from oil, dirt, and potential physical damage in the field. The maximal ranging distance is estimated at 3657m, 2286m for trees, and 2010m for deer and similarly-sized targets. 7x magnification, 16-19mm eye relief, and 6.5° view angle make the performance optimal in its class.
A single CR2A cap-secured battery provides power for operation and five brightness settings.
Thanks to the advanced design, robust construction, and multiple ranging modes, Viper HD 4000 is a versatile tool for archery, hunting, and surveillance applications.
