A 640x512 sensor has four times the pixels of a 384, and once you look through one it is hard to go back. The good news for 2026: true 640 scopes now start under $1,200. Here is how our 640 lineup stacks up, cheapest to flagship.
The C19-640 35mm at $1,199 on sale (regular $1,499) is the lowest-cost way into a 640 sensor in our store. No rangefinder, but the same core and image quality as scopes costing hundreds more.
The TPM A01 adds a 50mm lens and a built-in laser rangefinder for $1,399 on sale (regular $1,599). For $200 over the base 640 you get ranging and a bigger objective. This is the one we would buy with our own money, and it is in stock.
Prefer the lighter 35mm lens but still want ranging? The C19-640 35mm LRF is $1,399 on sale (regular $1,599) and excels in thick cover where field of view beats magnification.
The TPM-6J16 is our top 640 at $1,899 on sale (regular $2,200). The 54mm objective and premium core deliver the best image we sell, for hunters who want maximum identification range.
A 640 sensor puts more pixels on target at every distance, which means you identify animals farther out and track them easier in the scan. If your shots run past 150 yards, or you just want the best picture, 640 is worth the stretch. Our 384 vs 640 comparison shows side-by-side images.
