Although we appreciate that some conservation efforts require wild animals to be controlled, we have a strict anti-hunting policy. As such we cannot supply camera traps for the purposes of wildlife monitoring with the intention of dispatching any animal.
We work hard to minimise our impact on the environment. We recycle all cardboard, plastic, batteries and other packaging. For shop orders, all cardboard used is made out of 70% recycled material and is 100% recyclable. If you do receive any paper, plastic or polystyrene packaging, we have reused these materials from packaging that has been sent to us. Sustainable resources are used wherever possible. We think before we print. NatureSpy branded apparel is 100% certified organic made using solar and wind powered renewable energy and low waste, cruelty-free inks.
We’re a small organisation that aims to produce a big impact. Through our wildlife work we also want to educate people and communities about their local green spaces and wilder neighbours. In doing so we hope to achieve a dual purpose of encouraging people to care for and protect wild animals and habitats while using nature for their own health and well-being.

Pulsar Helion 2 XP50 Pro
New to thermal tech? We explain it all here...The Helion 2 XP50 Pro is Pulsar's most powerful thermal monocular to date, capable of producing highly detailed images suitable for precise wildlife work.
We’ve tested the XP50 Pro in a range of different wildlife monitoring scenarios and found that it is:
- Outstanding for observing mammals from bats to red deer
- Excellent for monitoring den boxes and bird boxes out to approximately 60m+
- Excellent for long range observations of medium to large mammals out to 1,800m (e.g. foxes, red deer)
- Good for observing medium and large birds out to medium range (e.g. blackbirds, geese)
- Good for observing smaller mammals out to medium range (e.g. bats, mice)
It features a 640×480 and 12µm core thermal sensor, which offers twice the resolution of more basic models and produces a superb thermal picture. However the main feature that sets this Pro model apart from other Helion models is its incredibly low NETD value of <25mK. This means the Helion 2 is able to differentiate very small variations in thermal radiation and consequently it can produce a very detailed image, enabling you to more accurately determine details about your subject animal.
The detection range for the XP50 Pro is 1800m, the base magnification is 2.5x, it has a digital zoom of up to 20x, and the 50mm lens offers a field of view 12.4°. Altogether these optics offer a very clear picture when looking through the viewfinder, and the wider FOV is particularly helpful when panning or following moving animals. In practice the working detection range is likely to be lower in most circumstances. For larger mammals in good weather conditions, the stated detection ranges are accurate. For smaller heat signatures, in more cluttered environments or in poorer weather conditions, the useful working distance is closer to a few hundred metres.
The XP50 Pro comes with the same great features as its predecessors. The start-up is instant, meaning you can quickly use it when in the field. It has a Picture in Picture function which allows you to zoom in on a secondary image on the screen whilst still maintaining your field of view. It comes with the standard 8 thermal colour pallets.
It can record video at a resolution of 1024x768, which is saved on an internal 16GB memory.
It has a WiFi module that allows you to view a livestream from the camera and adjust its settings on the free Stream Vision 2 app.
The Helion 2 can operate in temperatures ranging from -25°C to 50°C. Along with an IPX7 waterproof rating, updatable software and rechargeable IPS7 battery with life up to 10 hours, the Helion 2 is the undisputed standard of modern monocular technology.
The Helion 2 XP50 Pro comes with a three year warranty, the rechargeable battery comes with one year.

Ease of use
The XP50 Pro is an easy to use, handheld thermal monocular. When you need to use it, it turns on instantly - perfect for wildlife spotting. You can get up to speed and comfortable with its use within seconds.
It has a WiFi element that allows you to connect to on your smartphone or tablet using the free Stream Vision 2 app. The app shows you a live feed from the camera and allows you to change the settings as well as record videos and take pictures remotely (up to 10m). Viewing on a screen is great for minimising eyestrain (which can develop when looking through the viewfinder for extended periods) and is great for group viewing.
Using the supplied adapter it can be mounted on a tripod, which is great for minimising strain and handshake.
The XP50 Pro is made of a rugged magnesium alloy and is lightweight - weighing about 500g - so it can be hung around the neck without strain.
It's has an IPX7 rating so you can use it whatever the weather without any concern.
The IPS7 batteries provide approximately 8 hours of continuous operation and can be quickly replaced. These batteries charge quickly either in the unit connected by a USB or via the included charger station.
Warranty: The Helion 2 XP50 Pro comes with a three year warranty, the rechargeable battery comes with one year. All handled in house by NatureSpy.

Pulsar Helion 2 XP50 Pro Optics
Optical magnification: 2.5x Digital magnification: 20x (max)
Thermal Sensor: 640x480 @ 17µm <25mK NETD F.O.V.: 12.4°
The Helion 2 XP50 Pro features a 640x480 17µm thermal sensor and a F/1.0 lens that provides a detection range of up to 1800m for a deer-sized object.
In previous Helion series models the NETD value was sub 60mK. The new <25mK sensor, exclusively manufactured by ULIS for Pulsar puts Pulsar devices at the forefront of the market with the devices all featuring a better image in conditions where there is a low-temperature difference such as during rainfall, fog or cold mornings. These environmental conditions are the most difficult for thermal imagers and this new sensor will provide a clearer image for users. You can see what difference this makes below
