A 1534nm laser is eye safe at higher power levels than a 905nm laser, increasing its effective range for longer-distance targets. Additionally, the 1534nm laser offers the advantage of being undetectable by traditional night vision devices, enhancing its covert capabilities and is a preferred laser rangefinder wavelength for military systems.
The X4-LRF™ comes in Flat Dark Earth (FDE). Coming soon: Black or Olive Drab (OD) Green options. Note: The body is Type III Hard Anodize Finished - individual color shades may vary.
Yes, using the included ironsights.
Yes, it comes with a rechargeable CR123 battery.
Class 1 lasers are low powered devices that are considered completely eye-safe.
No. The X4-LRF™ has been designed to run standalone without ever needing to connect to another device or the internet. However, some of the more advanced configuration options are only accessible via a phone.
OLED Display
The X4-LRF™ has an UWB radio allows which allows it to host a personal-area, secured, encrypted network for wireless accessory communication (coming soon). The radio is OFF by default.
Yes. The UWB and Bluetooth® systems can be completely disabled.
The X4-LRF™ ballistic engine supports the vast majority of bullet and weapon types on the market.

Applied Ballistics
The X4-FCS™ and X4-LRF™ ballistic solvers support the vast majority of bullet and weapon types on the market.
The X4-FCS™ and X4-LRF™ ballistic solvers utilize temperature, humidity, pressure, pitch, roll and heading from the onboard sensors. Wind is utilized but must be manually entered (Kestrel compatibility coming soon).
Yes

A laser rangefinder is an electronic device that uses a laser beam to determine the distance to an object.
The 2K utilizes a 905nm commercial-grade laser. The 15K utilizes a 1534nm military-grade laser and is not detectable by night-vision devices. The 15K is quicker at taking ranges and ranging smaller targets than the 2K. Additionally, the 15K can take ranges more reliably than the 2K in adverse conditions such as fog and smoke.
Designed, Engineered, and Manufactured in the USA.
Yes, the X4-LRF™ must be sold to US Persons within the USA. (Coming soon: X4-LRF non-ITAR restricted version)
