The Thermal Advantage - How the latest thermal imagers offer a huge advantage in the field over traditional night vision.

A thermal imager is the ideal companion for wildlife observation, foxing at night, or for wildlife surveys. Scott Country stock a large range of thermal imagers from manufacturers such as Pulsar with their Quantum and Helion Series, Thermoteknix, seek ir, guide and torrey pines

Picture a wildlife cameraman on a remote woodland area at night, looking to spot a fox on a ridge which he can hear calling. With a traditional night vision device, at range he will only know the fox is there if he happens to pick up eye shine, so in fact could spend a long time scanning the ridge to try and pic out a shadowy shape against the background.

With a thermal imager, you can instantly scan the field and see any heat source whether it be a rabbit, a fox, or a vehicle.

Adding a hand held thermal imager to your equipment portfolio not only saves time in the field, but will bring a whole new perspective to watching wildlife at night.

Mike Powell from Sporting Rifle summed this up perfectly "Out foxing at night i could hear a fox calling yet i couldnt see anything apart from some rabbits in the valley when viewing through my Archer, turning on the Pulsar Quantum,  i was surprised to see two foxes a hundred yards in front of me, that i didnt even know where there!"

How Does a Thermal Imager Work?

A thermal imager consists of a germanium lens, microbolometer detector and an electronic processing system.

The germanium lens focuses infrared light which is emitted by objects in the field of view, whether it be an animal, a human hiding in bushes, or a vehicle with an engine and exhaust heat signature.

This focused light is then scanned by the microbolometer and the varying heat levels detected change its electrical resistance, which is then interpolated into a signal measured and processed into an image which appears on the OLED screen.

Whether you are looking to check the heat loss from a vehicle roof, or track the movements of a fox moving across a valley, the thermal imager will detect the infrared heat source and transmit it to your eye as a viewed image.

Thermal Imaging vs Traditional Night Vision

In completely dark conditions a traditional night vision device relies on a infrared LED light source to illuminate a subject, whether it be from moonlight or a infrared flashlight.

Traditional night vision devices, although operating in infrared, have a red glow from the emitters, and in the case of the Nite Site Spotter Extreme the IR array is so powerful it can often be seen clearly by animals in front of the device.

The thermal imager however can detect heat sources from extreme distance, or from close up, and allow you to view wildlife without being undetected, which is also ideal for covert surveillance.

Traditional night vision is of course less expensive than thermal imagers, however if you compare the Pulsar Helion with a detection range of 1800m, costing under £2600, with a Gen 3 Starlight Archer with a detection range of 400m costing £2499.99, then you can seethe difference in price is becoming less significant.

We recently visited the Galloway Hills to film red deer on a ridge approx 1000m away using the Nite Site Spotter and the new Thermoteknix TiCam 750LR

We scanned the ridge (1km) and with the Spotter we saw a hint of eye shine which gave away the position of an animal but we had no way of knowing if it was man or beast.

Powering up the Thermoteknix we scanned the ridge and instantly spotted approx 20 heat sources. Zooming in with the 4x optical zoom we identified them clearly as red deer.

With the Spotter the animals were totally unidentifiable, until we gave a red deer call, and all the hinds and stags turned to look at us, and the Spotter identified 20 sets of twinkling eyes in the distance.

Calling the deer closer, it was not until about 400m away that the Spotter started to identify a shape, outline and indeed a species, where as with the Thermal we were already counting points on the antlers of the stags!

Although the Nite Site Spotter could easily identify the animals at this range, the deer were spooked by the IR and stood and stared towards us, easily identifying our position, not ideal for covert surveillance where as the thermal imager could be used completely covertly, making it ideal for security or for anti poaching
