Frequently Asked Questions
Welcome to Further Wild. Below you'll find answers to some of the most common questions about binoculars, thermal imaging and our outdoor observation equipment.
If you can't find the answer you're looking for, please get in touch and we'll be happy to help.
Binoculars
What should I look for when choosing binoculars?
The right binoculars depend on how and where you intend to use them. Key factors include magnification, objective lens size, field of view, optical quality, weight, low-light performance and weather protection.
For wildlife watching and general outdoor exploration, 8x or 10x binoculars are popular choices. Higher magnification can provide more detail at distance, but may make it harder to keep the image steady.
What does 8x42 or 10x42 mean?
The first number is the magnification. An 8x binocular makes an object appear approximately eight times closer than it would to the naked eye.
The second number is the diameter of the objective lens in millimetres. A 42mm objective lens provides a good balance between light-gathering ability, image brightness, size and weight.
Are higher magnification binoculars always better?
Not necessarily. Higher magnification can provide more detail at greater distances, but it can also narrow the field of view and make the image more difficult to hold steady.
For general wildlife observation, hiking and outdoor use, a moderate magnification can often provide a more comfortable viewing experience.
What are roof prism binoculars?
Roof prism binoculars use a streamlined prism design that allows the optical tubes to be positioned closely together. This makes them compact and comfortable to carry, making them particularly popular for wildlife watching, travel and outdoor activities.
Are your binoculars suitable for wildlife watching?
Yes. Further Wild focuses on equipment designed for outdoor observation and exploration, including binoculars suitable for wildlife watching, nature observation, hiking and general outdoor use.
Individual products vary in their optical characteristics, so we recommend checking the product specifications for magnification, field of view, close-focus distance and low-light performance.
Can binoculars be used in low light?
Many premium binoculars perform well in low-light conditions, particularly models with larger objective lenses and high-quality optical coatings. However, conventional binoculars still require some available light.
For observation after dark, thermal imaging or night vision equipment may be more appropriate.
Thermal Imaging
What is thermal imaging?
Thermal imaging detects differences in infrared radiation emitted by objects and converts those differences into an image that can be viewed on a screen.
Unlike conventional optics, thermal imaging does not rely on visible light. This makes it particularly useful for detecting heat sources in darkness and other challenging viewing conditions.
What is the difference between thermal imaging and night vision?
Thermal imaging detects heat differences, whereas traditional night vision amplifies available light.
Thermal imaging can therefore detect heat signatures in complete darkness and can be useful in conditions where conventional optical viewing becomes difficult. Night vision, depending on the technology used, generally produces an image based on available or infrared-illuminated light.
Some modern multispectral devices combine thermal imaging with digital day/night viewing in a single unit.
What is a thermal monocular?
A thermal monocular is a handheld thermal imaging device designed to be viewed through one eyepiece or display.
They are generally compact and lightweight, making them useful for scanning, wildlife observation and outdoor exploration.
What are thermal binoculars?
Thermal binoculars use thermal imaging technology with a two-eye viewing system.
They can provide a more natural and comfortable viewing experience during longer observation periods, particularly when scanning large areas or observing wildlife at distance.
How far can a thermal imaging device detect something?
Detection range varies considerably between products and depends on factors such as sensor resolution, lens size, magnification, the size of the heat source and environmental conditions.
A manufacturer's quoted detection range should therefore be considered alongside other specifications rather than used as the only measure of performance.
What is thermal sensor resolution?
Thermal sensor resolution refers to the number of pixels in the thermal sensor, such as 256 × 192, 384 × 288, 640 × 512 or higher.
In general, a higher-resolution sensor can provide more thermal detail, although lens characteristics, image processing, viewing distance and environmental conditions also affect the final image.
What does NETD mean?
NETD stands for Noise Equivalent Temperature Difference. It is a measure of how sensitive a thermal sensor is to small differences in temperature.
A lower NETD figure generally indicates greater sensitivity to subtle temperature differences, although sensor performance should always be considered alongside the complete specification of the device.
Do thermal imaging devices work in complete darkness?
Yes. Thermal imaging does not require visible light because it detects infrared radiation associated with heat.
This is one of the key differences between thermal imaging and conventional optical equipment.
Does thermal imaging work through walls?
No. Thermal imaging devices generally detect infrared radiation from surfaces rather than seeing through solid walls or other opaque materials.
They may detect temperature differences on a surface caused by something behind it, but this is not the same as seeing through the material.
Does rain or fog affect thermal imaging?
Environmental conditions can affect thermal imaging performance. Heavy rain, dense fog, humidity and other atmospheric conditions can reduce effective detection and identification distances.
Always consider the manufacturer's specifications and the conditions in which you intend to use the device.
Choosing the Right Equipment
Should I choose binoculars, a thermal monocular or thermal binoculars?
It depends on what you want to see and when you intend to use the equipment.
Binoculars are ideal for conventional daytime observation, wildlife watching, hiking and viewing distant landscapes.
Thermal monoculars are compact options for detecting heat signatures, particularly after dark or in low-visibility conditions.
Thermal binoculars combine thermal imaging with two-eye viewing and are particularly suited to extended observation and scanning.
Some multispectral models combine thermal imaging with digital day/night viewing for greater versatility.
What should I consider when buying thermal binoculars?
Important factors include:
Thermal sensor resolution
Lens size
Thermal sensitivity
Magnification
Field of view
Detection range
Image quality
Battery life
Weight and ergonomics
Weather protection
Recording and connectivity features
Integrated laser rangefinder, where available
The best specification will depend on how and where you intend to use the equipment.
