How does the Rattler C V2 35-384 work as a clip-on?

It mounts in front of a daytime riflescope and projects a thermal image into the scope, so you aim with the scope's own reticle. You do not re-zero the host scope for thermal use.

What is the detection range?

With a 384x288 sensor and a 35 mm lens, AGM rates detection of a human-sized target at roughly 1,200 to 1,400 yards. Recognition and identification come at much shorter distances, so treat those figures as best case.

What battery does it use?

It runs on one 18650 rechargeable battery, which is common and easy to carry as a spare. Runtime depends on settings and whether the recorder and Wi-Fi are on.

Does it record video?

Yes. It has onboard recording and Wi-Fi for streaming to a phone through the AGM app. Recording and Wi-Fi draw more power, so expect shorter battery life with them on.

How does it compare with the 25 mm version?

The 35 mm lens gives more magnification and reach than the 25 mm model, at the cost of a narrower field of view. The 35 mm suits open ground and longer shots; the 25 mm suits tight cover and close work.

Is it worth it over a dedicated thermal scope?

It is worth it if you already have a good daytime scope and want thermal without buying a second optic. A dedicated 640-resolution thermal scope gives a sharper image and simpler handling, but costs more and replaces your daytime setup.
