- Faster Range Response than Gen I: The Gen 2 system delivers faster returns and features improved beam divergence over Gen I for superior precision on small targets. This upgrade ensures the laser stays focused on the intended target rather than background clutter.
- 10,000+ Ranges on One Battery: A single CR123 battery provides enough power for more than 10,000 distinct range measurements. You can rely on this unit in extreme conditions, from -40°F cold to 140°F heat.
Maztech X4 LRF Review
What are some common accessories to add to the Maztech X4 LRF?
Fire Control System Integration
- Maztech X4-FCS™ Fire Control System: This system is sold separately and integrates directly with the X4-LRF™. It allows the rangefinder to send instant target distance and ballistic solution data to the fire control system, creating a complete engagement package.
Mounting & Configuration
- X4 Diving Board Mount: This specialized mount allows the operator to place the X4-LRF™ directly above the X4-FCS™ Fire Control System. This creates a streamlined, co-aligned unit on the rifle's top rail.
Remote System Operation
- X4 Low-Profile Remote: Included with the Maztech LRF™, this wired remote can be mounted anywhere on the weapon system. It gives the operator the ability to activate the laser and rangefinder functions remotely for efficient operation.

Maztech X4 LRF FAQs
What is the Applied Ballistics® solver and what does it do?
The Applied Ballistics® solver is like a smart computer built right into the rangefinder. It automatically calculates a precise firing solution, which tells you exactly where to aim. It uses data from the built-in weather and motion sensors to remove the guesswork from long-range shots.
What is the difference between the Maztech X4 LRF 2K and Maztech X4 LRF 15K models?
The main difference is the maximum ranging distance. The Maztech X4-LRF 2K model can measure distances from 10 to 2,180 yards. The X4-LRF 15K model is more powerful and can measure distances from 25 all the way out to 16,400 yards. The 15K model's ranging laser is also not visible to night vision devices.
Why does the rangefinder have weather and motion sensors?
The rangefinder has a built-in "weather station" with environmental and motion sensors. These sensors provide the onboard computer with the live data it needs, like temperature and the angle of the rifle, to create an accurate firing solution. This ensures your aiming correction is perfect for your exact situation.
Why do I need to calibrate the compass?
You need to perform a simple calibration routine after installing the battery. This is done so the X4-LRF™ can show an accurate compass heading on the display, which is one of the factors used to calculate your firing solution.
Do I need to use the smartphone app?
While you can set up everything directly on the device, using the Maztech Companion App on your smartphone is the most efficient way to set up your ballistic profiles. The app connects to the rangefinder using Bluetooth® and makes managing your weapon and ammo information simple. You can also set up and manage up to 30 different weapon profiles without ever using a smartphone.
What are the visible and IR aiming lasers for?
The X4-LRF™ has two co-aligned aiming lasers to help you see where the rangefinder is pointed. The visible laser is a red dot you can see with your naked eye, perfect for daytime use and setup. The IR (infrared) laser is invisible to the naked eye but can be seen with night vision devices, allowing you to aim and range targets in the dark without being seen.
