Thermal Clip-On
A thermal clip on mounts in front of the riflescope you already shoot, turning it into a thermal optic without removing it or changing your zero. Keep the day glass you trust, clip on the thermal at dusk, and take it off again when you want your normal sight picture back.
How to choose a clip-on
Start with resolution and lens. The RICO Micro V2 384x288 25mm (RL25V2) and the RICO Micro RH25 V2 640x480 25mm are small iRay clip on thermal units; the 640 version shows more detail at distance. For longer shots, the RICO Hybrid 384 3X 50mm 90Hz comes with a free laser rangefinder, and the InfiRay Outdoor Hybrid Compact 3.5x 640x480 LRF 50mm pairs a 640 sensor with a 50mm lens and an LRF.
Then think about how you will use it off the rifle. Some clip-on thermal imager units double as handheld scanners, like a thermal monocular. The iRay Mate Monocular adaptor turns a compatible unit into a handheld monocular, so one optic scans the field and then goes on the gun.
Keep in mind that a clip-on adds weight and length ahead of your scope, and your day scope's magnification multiplies the thermal image, so lower power settings usually give the cleanest view. Mount height and eye relief matter too, and we are glad to help you match a clip-on to your setup.
Want a dedicated thermal sight instead? Compare our thermal scopes, or see LRF capable scopes that take an add-on rangefinder module.
Frequently Asked Questions
Are clip-on thermals any good?
They are a smart choice if you already own a day scope you like. A good clip-on keeps your zero, comes off in seconds, and lets one rifle cover daytime and night hunts. The tradeoff is extra weight and length up front. The 25mm RICO Micro units here are among the smallest thermal units we carry.
What is the best thermal clip-on for the money?
It depends on your distances. For predator calling at typical calling ranges, the 384x288 RICO Micro V2 covers the job in a small package. If you shoot farther or want sharper identification, the 640x480 RICO Micro RH25 V2 or a 50mm hybrid with LRF gives you more reach.
Is it illegal to have a thermal camera?
Owning a thermal camera or clip-on is legal in the United States. Using one to hunt is a separate question, and rules on night hunting and thermal optics vary by state and species. Many thermal devices also fall under export restrictions, which is why we only ship to US addresses.
Can my phone be used as a thermal camera?
Not by itself. Phone cameras see visible light, not heat. You need a plug-in thermal attachment or a dedicated thermal device to read heat signatures. Some thermal optics connect to a phone app over Wi-Fi so you can view or record the image, but the sensing happens in the optic.
Can someone see inside my house with thermal or night vision?
No. Thermal reads surface temperature, so it sees heat on the outside of a wall, not the people behind it. Glass blocks thermal too, which is why a thermal scope can't look through a car or house window. Night vision needs a clear line of sight, just like your eyes.
