Kahles Helia RF 10x42 Details

With the 10x42 version of the Helia RF, you are sacrificing a little in terms of the field of view and low light performance compared to the 8x42 model. However, in return, you gain a higher image resolution and therefore more reach. These Kahles binoculars have a tough aluminium chassis and are fully waterproof, they are also filled with dry nitrogen gas to protect the internal optics from fogging. This along with the powerful laser that has a maximum range of 1500 meters and many of their other impressive features make the Kahles Helia RF 10x42 an ideal rangefinding binocular for the hunter who is often out in the open and/or targeting objects at slightly longer distances.

Description of Kahles Helia RF Binoculars

Taking from their wealth of knowledge in ballistics and optics, Kahles have combined the impressive level of optics found on their flagship Helia binoculars with a high-end laser rangefinder to offer the discerning hunter a quality instrument that competes very well in within its price range and gives you the best chance of success on your hunt. These Kahles binoculars come in 8x42 and 10x42 configurations to match your preference of wide angle and superior low light performance versus long-distance observation. Available in a distinctive brown finish, the Kahles Helia RF Binoculars certainly stand out from the competition, but at the same time blend in with nature when out in the field and offer a good level of camouflage.

Important Features

As well as camouflage, the rubber armour exterior ensures a slip-free surface in all weather conditions and protects a tough aluminium chassis underneath. Fully sealed the Helia RF is both waterproof and thanks to the nitrogen filling, is fog proof as well. The integrated laser rangefinder has a range of between 10 and 1500 meters and the heads-up OLED display has five brightness settings for ranging in all light conditions. An intuitive menu navigation enables quick and easy adjustments to settings and modes. Here a standard range can be displayed as well as an angle-compensated measurement that takes ballistics into account. The rangefinder on the Helia RF also has a scan mode that continuously supplies distance information as you pan about and is perfect for moving targets. The Helia RF is powered by an easy to find CR2 battery and is said to provide over 3000 measurements before the need to change.

Optical Properties

A large, centrally located focus wheel allows for accurate single handed focal adjustments, even whilst wearing thick winter gloves and the diopter adjustment ring is positioned in the standard position near the eye-piece and enables you to compensate for any differences in vision between your left and right eyes. The twist-up eyecups have 4 click-stop positions to enable a good level of fine tuning, which in combination with the eye-relief of 18.5mm (8x42) or 16.5mm (10x42) makes these an excellent option for eyeglass wearers. Field of view on both models is more than satisfactory, indeed they compare very well with other leading rangefinder binoculars in the market.
