Thermal Imager Add-Ons for Versatile Shooting Setups
R Macleod & Sons offers a growing range of thermal imager add-ons, giving shooters the ability to convert their existing daytime scopes into thermal-capable optics. These clip-on devices mount either in front of the scope or to the rear, offering a flexible solution for those who want thermal performance without switching between optics or re-zeroing their rifle. Thermal add ons are designed to detect heat signatures from animals, people, or equipment, making them especially useful for pest control, deer stalking, and land management – particularly in low light or full darkness.
Whether you’re an experienced shooter or new to thermal technology, these devices offer a cost-effective way to access the advantages of thermal imaging without replacing your current optic.
What is a Thermal Imager Add-On?
A thermal imager add on is a compact thermal unit that attaches to your existing riflescope. Unlike standalone thermal riflescopes, these devices use your current optic for aiming and magnification, with the thermal unit feeding a thermal image into the scope's view.
There are two main types:
.Front-mounted clip-on units - which attach to the objective end of your riflescope.
.Rear-mounted clip-ons - which attach behind the eyepiece (less common with thermal, more common in digital NV).
Front-mounted thermal units are the most popular, as they allow you to maintain your normal shooting position and use your scope’s reticle as usual. There’s also no need to re-zero, provided the clip-on unit is mounted properly and aligned.
Benefits of Thermal Add Ons
.No need to switch rifles or scopes – Use the same rifle setup for day and night work.
.Quick to fit and remove – Ideal for pest controllers and landowners who need flexibility.
.Zero retention – No need to re-zero when the device is removed and reattached properly.
.Cost effective – A great way to add thermal capability without purchasing a dedicated thermal riflescope.
Popular Brands and Models
We stock thermal clip-ons from trusted brands such as Pulsar, Hikmicro, and InfiRay, all known for delivering sharp thermal imaging, robust build quality, and reliable performance in the field.
Examples include:
.Hikmicro Thunder Series – These devices can be used as both standalone scopes and clip-ons with the correct adapter. Options include the Thunder TQ50 and Thunder TE19C, offering different sensor resolutions and detection ranges.
.Pulsar Krypton Series – High-performance clip-ons with large detection ranges and high thermal sensitivity.
.InfiRay CL Series – Compact and lightweight, designed specifically for clip-on use with excellent image clarity and battery life.
Each thermal add on includes clear product specifications, including sensor resolution, display type, detection range, weight, and mounting compatibility. Be sure to check that your existing scope is suitable – some clip-ons work best with scopes that have low magnification (typically 1–6x for optimal results).
Accessories and Mounts
We also stock a range of thermal imaging accessories, including clip-on adapters, mounting collars, and carry cases. It’s important to use the correct adapter for a secure fit and reliable alignment. If you’re unsure which model or mount you need, our team can advise based on your existing scope and intended use.
