Compact, powerful and easy to use, the Delta Titanium RF-4000 is built for anyone who needs fast, reliable distance readings in the field — whether that’s shooting, hunting, sailing or general outdoor use.

It measures both stationary and moving targets quickly and accurately, with distance data displayed directly in the eyepiece, overlaid on the target. That means no looking away, no clutter — just clear, instant results while you stay focused on what you’re ranging.

With a working range from 4.6 metres out to 3660 metres and an accuracy of ±1 metre, the RF-4000 delivers dependable readings in around 1.5 seconds. Angle compensation up to ±89° makes it especially useful on uneven ground, hillsides or elevated positions.

Optically, the 6× magnification and multi-coated lenses give a bright, sharp image for confident target identification. Despite its capability, the unit remains lightweight at just 190 g, water-resistant (IPX4) and easy to carry all day.

Powered by a single CR2 battery and backed by a 5-year warranty, the Titanium RF-4000 is a practical, no-nonsense rangefinder designed to work quickly, clearly and reliably when it matters.

Best suited for:

Less ideal if:

You predominantly use very close distances (<20 m) — some compact rangefinders are optimised for ultra-short range.

You require built-in ballistic calculators — this model focuses on accurate distance measurement rather than full ballistic solutions.
