With an improved range over its successor, and in a lighter and smaller housing, the Leica 7x24 Rangemaster CRF 2700-B Laser Rangefinder is a useful tool for taking long-range shots with confidence — without weighing you down.

Its 2700-yard range and fast 0.5 second processing rate gives you a critical edge when it matters most. Integrated into the rangefinder is a ballistic computer that uses multiple readings, including range, angle to target, barometric pressure, temperature, and ammunition load, to adjust the displayed distance plus the number of click adjustments to your riflescope, so you can compensate correctly for improved shot accuracy. The ballistic computer and companion EHR (Equivalent Horizontal Range) are accurate to more than half a mile. The Rangemaster 2700-B is further upgraded with a microSD memory card slot that allows you to use Leica's on-line ballistic calculator to customize specific ballistic curves and load them onto the device to improve shot accuracy even more.

A simple one-button interface provides critical ease-of-use and a red LED display clearly shows the ranging information in your line-of-sight in an uncluttered layout. An ambient light sensor automatically adjusts the display brightness so you'll always be able to clearly see the information without overloading your vision. Designed for durability, the housing is made of a lightweight and durable carbon fiber reinforced ABS plastic. Weighing in at just 6.5 ounces, including its CR2 battery, the Rangemaster CRF will be a valuable addition to your kit.

Optical Performance

  • Moderate 7x magnification brings target in close without sacrificing exit pupil or eye relief
  • 24mm objective lens helps to maintain a slim form-factor
  • Compact roof prism design keeps housing easy to hold one-handed
  • P40 phase-correction prism coating improves color rendition and contrast
  • HDC fully multi-coated optics: Abrasion-resistant to protect exterior lens surfaces and anti-reflection to improve light transmission and contrast
  • AquaDura lens coatings repel water, oil, and grime to keep lens clear and clean
  • 347' field of view at 1000 yards

Laser Rangefinder

  • Measures in yards or meters, selectable by user
  • Invisible FDA Class 1 eye-safe IR laser
  • Beam divergence of approximately 0.5x1.2 MRAD is an improvement over earlier models
  • Simple round center aiming reticle is easy to see without obscuring targets of all sizes
  • Metering range from 11-2700 yards reaches further than previous model
  • Metering accuracy of ±0.5yd from 11 to 220 yards; ±1 yard to 340 yards; ±2 yards to 875 yards; ±0.5% from 875 to 2700 yards
  • Spot and continuous scan mode calculates range in as little as 0.5 seconds
  • Runs on one included CR2 battery; good for up to 2,000 measurements at 68°F


  • Integrated inclinometer measures upward or downward angle relative to target
  • Internal barometric and temperature sensors measure atmospheric conditions that can affect bullet trajectory and ballistic arc
  • Built-in ABC ballistic program compiles data for angle of incline, temperature, barometric pressure, and ammunition type for precise hold-over/under with displayed riflescope MOA adjustment (clicks) for improved shot accuracy
  • Twelve pre-programmed ballistic curves to choose from
  • Equivalent Horizontal Range (EHR): An algorithm that uses distance and angle to calculate an adjusted range
  • ABC is accurate to 1000 yards (914 meters) EHR system accurate to 1200 yards (1100 meters)
  • Calculates range, including EHR, in 0.5 seconds
  • microSD card slot allows the use of pre-loaded ballistic curves from the Leica on-line ballistic calculator

Use and Handling

  • Convenient single-button activation and operation
  • In-view LED displays in red for easy viewing in all light conditions; range displayed up to 0.1 yards/meters
  • Options to display angle, temperature, and pressure in-view
  • Ambient light meter with automatic brightness adjustment
  • ±3.5 dioptric correction enables reticle to be properly focused
  • Fold-down rubber eyecup for comfortable use with or without eyewear
  • Long 15mm eye relief
  • Comfortable 3.4mm exit pupil

Construction Details

  • Lightweight, impact- and temperature-resistant carbon fiber reinforced ABS plastic housing
  • Ergonomically designed for comfortable one-handed use
  • IPX7-rated, waterproof and submersible to 3.3 feet
  • Broad -4 to 131°F operating temperature range; -40 to 185°F storage temperature range
  • Compact 4.4x2.9x1.3" form factor is smaller than previous model
  • Light 6.5-ounce weight, including battery, is lighter than earlier model
