What it is best for
The TM35-384 is the long-reach 384 Sidewinder, for hunters who want the premium sensor and image quality but prioritize distance over a wide view. It excels at glassing open ground and confirming game at long distances.
Key features and specifications
- 384×288 12-micron sensor with sub-20 mK NETD
- 35 mm F1.0 lens with a narrower, longer-reaching field of view (~39 ft at 100 yd)
- 3x base magnification, 3-24x digital zoom
- Sharp 1024×768 OLED display, 50 Hz refresh
- 64 GB built-in memory, video and audio recording
- Removable 18650 rechargeable battery; spares supported
- Wi-Fi and AGM Connect app, USB-C power, IP67, rubber-armoured body, 5-year warranty
Trade-offs and who it is not for
The longer lens narrows the field of view, so it is less suited to fast, close scanning than the TM25-384. For the cleanest far-distance image, a 640 Sidewinder pulls more detail; this is the long-reach 384 option.

- If you want a wider view: AGM Sidewinder TM25-384 Thermal Monocular
- If you want a 640 image: AGM Sidewinder TM35-640 Thermal Monocular

FAQ
- How is the TM35-384 different from the TM25-384? It’s the same premium 384 sensor but with a longer 35 mm lens for more reach and higher base magnification, at the cost of field of view.
- Should I choose the TM35-384 or the TM35-640? The 640 gives a noticeably more detailed image at distance; the 384 costs less and is excellent for most long-range scanning.
- Is it waterproof and rugged? Yes, with an IP67 rating and a rubber-armored housing built for demanding outdoor use.

I had an earlier version of this and lost it so got the newer version. AGM has been improving their monocular for earlier versions with better resolution plus other features. Nice to see and it was delivered within 48hours after ordering.
It works great for the price range.
