The Delta RF-4000 laser rangefinder delivers dependable long-range measurement in a compact, easy-to-carry package. This 6×23 mm unit reads from roughly 4.6 metres to around 3660 metres with ±1 metre accuracy, giving hunters and precision shooters the confidence to confirm distance on game, terrain features or steel. Its ED-grade optical system and wide field of view provide a bright image and quick target acquisition, while the in-ocular display presents clear readings that remain legible in variable light. With a comfortable grip and intuitive controls, it’s built for fast, one-hand operation in the field.

Engineered for Performance in the Field

A robust, weather-resistant housing (IPX4) helps the RF-4000 handle drizzle, dust and temperature swings common in Australian conditions. Coated glass and a 23 mm objective maintain contrast at dawn and dusk, while crisp internal electronics deliver rapid returns—typically around 1.5 seconds—so you can make a decision without losing the moment. The unit’s compact dimensions and ~190 g weight keep it unobtrusive on a lanyard or in a chest rig, and the supplied CR2 battery offers long service life for extended trips away from town.

Precision-Driven User Experience

Whether you’re clearing brush, ranging a big hillside or confirming steel, the RF-4000’s scan and target priority modes make it simple to grab the right reading. Angle/EHR compensation calculates the equivalent horizontal distance on steep uphill or downhill shots, helping you apply the correct hold. The clean display, straightforward two-button interface and tactile housing are easy to use with gloves, while the 6× magnification balances reach and stability for handheld ranging out to serious distances.

Reliable, quick and versatile, the Delta RF-4000 is a smart companion for hunting, long-range practice and general field use. With long-range capability, angle compensation and a bright optical view, it helps you range confidently and act decisively.
