Hello and welcome to another episode of Optics Trade Debates. Today we’re here to talk about two Yukon products that belong into the category of digital night vision monoculars or scopes, available on our webpage. To be a bit more specific, we will compare Yukon Ranger RT 6.5×42 and 6.5×42 S. Let’s dive in.
This is the latest NV monocular that Yukon has launched onto the market. It comes in two versions, Ranger RT 6.5×42 and 6.5×42 S. These devices utilize a 640×480 CMOS sensor with 2 different IR illuminators (short range and long range). It features stream vision capabilities, meaning that the user can connect via Wifi to their phone and observe the image on phone screen.
Yukon has 8GB of internal storage, that means plenty of space for videos and photos. Another 8 gigabytes of additional storage can be added by inserting an SD card. Yukon Ranger models also feature a video output and the user can record the observed image with an external video recorder.
Both models also have a 640×480 display, and with that, the same pixel count as on the CMOS sensor. Since Yukon Ranger RT 6.5×42 and 6.5×42 S are digital devices, they can be exposed to bright daylight without fear of damage. Another clear advantage of digital NV monoculars is their longevity as their lifespan is not limited as it is in the case of photocathode-based analog night vision devices.
From the optical and physical point of view, Yukon Ranger RT 6.5×42 and 6.5×42 S are completely the same. The difference lies in the IR illuminator or, more accurately, in the wavelength of the long-range illuminator installed on the Yukon Ranger RT 6.5×42 S model. Both IR illuminators on the standard Yukon Ranger RT 6.5×42 have a wavelength of 850 nanometres. This is a liminal value with that, certain animals can detect the emitted light.
The range of detection or recognition on the standard model is about 450 metres, while the S version has a shorter range of 350 metres. That’s because the latter one has a different long-range IR illuminator than the standard Yukon Ranger RT 6.5×42 model, one that uses 940 nanometres of wavelength. Although the range of detection is considerably shortened, the advantage of a device with such long-range IR illuminator is that the emitted light is completely invisible to all animals. It’s an easy compromise for wildlife observers and hunters who don’t want to spook the game.
Many customers wonder which model is the right choice for them. For people who are interested in night vision for security reasons, on the sea and those who primarily observe inanimate objects such as buildings and terrain, the standard Yukon Ranger RT 6.5×42 model is the better choice. It will provide a longer range of detection and observing details is made much easier than when using the S model variant. On the other hand, wildlife enthusiasts and hunters will happily sacrifice a bit of detection range in order to enjoy the completely invisible IR illuminator of Yukon Ranger RT 6.5×42 S model.
