Binoculars Kahles Helia RF 8x42.
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.
