Yukon Photon XT 4.6 x 42 S / L
Digital Night Vision Rifle Scope

100% Performance - 0% Gimmicks! This new and innovative digital night vision riflescope delivers top performance at a low price.

These are the features that we really like about this scope:

  • Image quality is very good: good contrast, easy to focus
  • Black and white image: better low light performance than colour CMOS
  • Very easy to us: only one button and one dial controls all functions
  • Very light and easy to mount: standard 30mm tube accepts variety of mounts and accessories
  • Choice of 18 reticle combinations: six different reticle designs in 3 colour options
  • 3-stage LED or Laser IR illuminator: 150m / 260m detection range
  • Auto brightness control with manual adjustment: easily altered with brightness dial
  • Excellent battery life with 2x AA batteries: red low light indicator comes on before discharge
  • Video-out socket: analogue signal can be recorded, or viewed through a LCD screen
  • Recoil resistant: can be used on heavy recoiling rifles such as .375H&H Magnum
  • Price: a fully functional night vision scope for the same price as a daylight scope!

Yukon Photon 4.6x42S/L

The 'S' version has a 3-stage LED IR illuminator that is suitable for shooting at close/medium range (up to 120 metres), and when fitted with a Pulsar L-915s laser IR 'stealth' illuminator, over 200m.*

The factors that limit distance performance are resolution and image contrast. Using additional infrared is necessary in extreme darkness to produce an image where the target is clearly visible.

The following tests were conducted by ourselves in starlight conditions, and demonstrate the effective illumination distance of the in-built laser IR illuminator. We also ran the same tests using an optional Pulsar L-915 laser IR 'stealth' illuminator. Only one illuminator was used at a time.

Our tests revealed that the Yukon Photon XL 4.6x42L has a shooting distance of up to 200 metres, when used with the in-built laser IR.

These two images above are illuminated with the in-built 780nm laser infrared illuminator, set to full power, with the Yukon Photon XT brightness control set to medium.

Adding extra illumination for increased distance

The addition of a Pulsar L-915s 'stealth' IR laser flashlight increases the working distance of the Yukon Photon XT to 350m.

The long 915nm wavelength is totally invisible to humans and animals alike, and has a 100% invisible emission window.

The beam can be focussed to spot or flood, and the power can be adjusted for comfortable use even at close range.

The Yukon Photon XT has a highly infrared sensitive CMOS sensor, that enables the use of longer wavelength infrared 'stealth' illuminators than other digital daylight / night scopes that have colour CMOS sensors, and lower IR sensitivity.

The Pulsar L-915s laser IR flashlight used to take these images has a 100% invisible source, and cannot be seen even at close range.

Using a Pulsar L-808s IR laser flashlight will increase the detection range of the Yukon Photon XT to 450m, though the source can be seen as a tiny red dot.

Note: The above images are captured from a video. The actual image is clearer than when viewed through a Yukon Photon XT eyepiece.

New Yukon Photon XT 4.6x42s. Relaunch of an 'old' favourite.

October 2014

The new Yukon Photon XT4.6x42s is the latest version of the highly successful Yukon Photon that has been exclusively available in the UK for the past 18 months. The new Yukon Photon XT is mechanically simpler, lighter, and has new features that add functionality and value.

For those not familiar with the Yukon Photon, it is a very competent night vision scope, that performs very well for its price, and does not sacrifice night performance by rendering a colour image. This produces a noticeably clearer image.

Our tests with the 's' version of the Photon XT easily observed our test human and his dog at 150 meters in starlight conditions, using the in-built LED IR illuminator. Our 'subjects' could be seen when the IR was set to medium, but were clearly visible on the high setting. The addition of a Pulsar L-915 IR 'stealth' illuminator enabled us to detect our human at 350 metres. The clarity was still good. We will be conducting tests with the 'L' version of the Photon XT when it becomes available.

During the test, we compared the Photon XT to a Pulsar Digisight N770. Whilst the Digisight produced a noticeably better image, the Photon would easily compete up to 100 metres, after which, the Digisight was clearly better. In 1/4 moon conditions, we could see our subject with the Digisight without any IR illumination when SumLight was activated. The Photon XT has no SumLight, so is 100% dependent on IR in 1/2 moon or less.

The Photon XT uses 2 AA batteries. When tested with our GP3000 rechargeable batteries, we had a continuous discharge time of 96 minutes with the brightness set to 6. The battery indicator changed to red 10 minutes before the unit shut down. We were very impressed with this result.

The reticle can be selected to red, green or white, and there is a choice of six designs. These can be selected on-the-fly without loss of zero. The Photon XT is a reticle moving system.

I recommend the Yukon Photon XT 4.6x42s for shooting small and large game in open areas when used with infrared. The price is very competitive, and I know that a lot of animals will fall to these scopes.
