The Leica Rangemaster CRF R laser rangefinder is a practical tool for ecologists. It allows to accurately measure distances up to 1800 meters, useful for migratory monitoring, faunal inventories, transects and the study of animal behaviors. Its compact size and light weight of 180 g make it easy to carry in the field and use with one hand, even in difficult conditions. With a fast measurement time and clear display, it ensures reliable and efficient readings. Robust and waterproof, it is ideal for extended outdoor outings, combining performance and ease of use.
Main features
- Magnification: 7x (monocular usable with one hand)
- Objective diameter: 24 mm
- Field of view at 1000m: 115 m
- Exit pupil: 3.4 mm (correct for prolonged observations)
- Linear measurement range: 10 to 1800 m
- Minimum measurement distance: 10 m (adapted forest surveys or proximity transects)
- Measurement accuracy:
- 0.5 m from 10 to 200 m
- 1 m from 200 to 1000 m
- 0.5% beyond 1000 m
- Measurement time: 0.3 s (useful for situations where animals move quickly)
- Scan Mode: allows continuous measurement, convenient for tracking fast moving animals or counting multiple individuals on a transect
- Display:
- Automatic brightness LED screen: easy reading under all conditions
- Selection meter/yard
- Ergonomics:
- Weight: 180 g (ultra light, long-lasting wear without fatigue)
- Dimensions: 113 x 78 x 35 mm (compact, fits in a field vest pocket)
- HDC TM Water-Repellent Coating, Robust Construction and Waterproof to 1 Meter
- Diopter setting: +3.5 to -3.5 dpt (adaptable to everyone’s sight, same glasses wearer)
- Retractable eyecups for users with or without glasses
- Energy: 1 lithium CR2 battery (about 3000 measurements at 20°C)
Naturalistic use recommended
Wildlife tracking (transects, remote visual surveys, discrete animal spotting)
Distance measurement in the field for scientific protocols and mapping
Assistance in the evaluation of habitats and estimation of group sizes at a distance
Benefits for wildlife monitoring & field research
- Ideal for estimating without disturbing: allows assessing the distance to animals that are difficult to approach or fierce, limiting transect escape biases and abundance estimation
- Precision on varied terrains: slope correction (EHR) for hilly, mountainous environments, cliffs or ripisylves
- Versatility in difficult conditions: contrasting and clear optics even in low light, mist, or undergrowth
- Field safety: invisible laser and safe for wildlife and the user (class 1 EN/FDA)
- Intuitive use: only two buttons, establishing an immediate grip on the field
Limits for the ecologist/naturalist
No angle displayed directly (only the corrected distance is)
No GPS geolocation or storage of measured points (consider an external sketch or GPS for georeferenced inventories)
