Steiner eRanger LRF 10×42 Binoculars

Steiner eRanger LRF 10×42 Laser Rangefinder Binoculars – Article No. 23180900

The Most Advanced Hunting Binoculars with Distance Measurement on the Market

When it comes to combining precision optics with intelligent rangefinding technology, the Steiner eRanger LRF 10×42 sets a new benchmark. Designed from the ground up for serious hunters, these laser rangefinder binoculars bring together outstanding image quality, a laser range of up to 3,000 metres, and the game-changing Impact Locator — all in a slim, robust, ergonomic package built to perform in real hunting conditions.

Impact Locator & Steiner Connect App 2.0 — Find Your Game Every Time

The feature that truly sets the eRanger LRF apart is the unique Impact Locator, working in combination with the Steiner Connect App 2.0 (available free on both the Google Play Store and Apple App Store). Once you’ve taken your shot, the Impact Locator displays the exact measured point and navigates you directly to the position via GPS — whether you’re searching through long grass, dense cover, at dusk, in darkness, or across long open distances.

Through the app you can also review and manage the last three stored measurements, along with a full overview of all measurements and coordinates — keeping everything organised and accessible right from your phone.

Laser Rangefinding — 25 to 3,000 Metres

The eRanger LRF offers an impressive measurement range starting from just 25 metres out to 3,000 metres, with unmatched precision and measurement accuracy throughout. The display is arranged for maximum clarity and overview, ensuring you can read information quickly and safely in any situation. Practical hunting functions include a tilt angle display and compensated distance readings, both of which help you accurately assess the hit point regardless of the angle of the shot.

Optical Performance Built for Low Light and Long Range

The 10x magnification paired with a 42mm objective lens delivers sharp, detailed images across a wide range of conditions. The 85% light transmission and twilight factor of 20.49 ensure exceptional brightness and contrast when light levels drop — exactly when hunting is often at its most critical. The High-Contrast Optics further enhance image clarity and target definition, making it easier to pick out game against complex backgrounds.

The 105 metre field of view at 1,000 metres gives you a wide, comfortable view for scanning terrain, while the 4.2mm exit pupil ensures a bright image even in demanding conditions. The Fast-Close-Focus system allows for quick, precise focusing, with a minimum close focus distance of just 5 metres — useful for identifying nearby game or checking surroundings at close range.

Bluetooth Connectivity with the Steiner eRanger 8 Rifle Scope

For hunters who already own a Steiner eRanger 8 rifle scope, the eRanger LRF binoculars offer a seamless Bluetooth connection that transmits the measured distance directly to the rifle scope display the moment you range a target. This immediate data transfer eliminates the need to manually input or recall distance figures, allowing for a faster, safer, and more precise shot — an invaluable advantage when every second counts.

Robust, Ergonomic Design Built for the Field

The eRanger LRF has been engineered with both durability and handling in mind. The slim roof-edge design not only gives the binoculars a clean, modern profile but makes them particularly comfortable to hold and operate whether you’re sitting in a high seat or moving on a stalk. The aluminium housing provides a robust and reliable structure capable of withstanding impacts of up to 11G, while the NBR-Longlife rubber armouring adds grip, protection and long-term resilience.

At 140mm wide, 210mm tall and 56mm deep, with a weight of 1,100g, the eRanger LRF is compact and manageable enough for extended carry without fatigue. The ergonomic eyecups ensure comfortable viewing for extended glassing sessions, and the standard belt connection keeps them accessible and ready at all times.

All-Weather, All-Season Reliability

Built to perform in the harshest hunting environments, the eRanger LRF is waterproof to 1 metre and nitrogen-filled to prevent internal fogging caused by temperature changes or moisture. It operates reliably across a functional temperature range of -20°C to +50°C, making it equally at home in a frozen northern European winter or the heat of a summer stalk.
