Forester 6x21 GENII rangefinder

What it is and what it does
The Forester 6x21 GENII is a handheld rangefinder from Vector Optics designed for hunting, shooting and golf. It measures distance, provides angle/true horizontal distance, and can determine height and line-of-sight distance to targets.

Key specifications
It features 6× magnification, a 21 mm objective and a 15 mm exit pupil, with a 6° field of view. The manufacturer specifies a measurement range of 5 to 1500 meters (also indicated up to 1600 yards) with an accuracy of ±1 m / ±1 yd and a measurement response time of 0.2 s. Angle measurement covers -70° to 70°. The unit uses a 905 nm laser and offers scan and multi-target modes. Readouts are shown on an OLED display suitable for low-light conditions. Manufacturer guidance for detection distances by target type: building (concrete) ~1100 m (1200 yd); tree ~825 m (900 yd); deer ~640 m (700 yd); golf flag ~410 m (450 yd).

Dimensions and power
Dimensions are 98.5 × 77 × 37 mm and weight is 130 g. The device requires a CR2 (3 V) battery according to the technical sheet.

Compatibility
Described as a portable handheld unit for distance measurement; the datasheet does not list mounts or caliber compatibility, so it is not specified for fixed mounting on optics or firearms.

Box contents and accessories
The manufacturer lists the rangefinder, cleaning cloth, manual, adjustment key/plastic, lanyard/strap and a nylon case in the box. The CR2 battery is not listed among included accessories and should be purchased separately if not supplied.

Important notes
The manufacturer does not state the body material. IPX4 indicates splash resistance, not waterproofing. Maximum ranges are indicative and depend on target reflectivity and environmental conditions. Verify you have a CR2 battery before first use to avoid returns.
