I own a CNVD-T and several other mil & commercial thermals (Halo LR, China Skeet, M18 Recon, UTM, MTM) Have owned (Halo, LWTS, Reap 35 & 60, CRATOS, Pulsar Trail XP, Armasight)... Not nearly as many as Horta or some of the other guys on here, but enough to give a good sample
The thing to remember with the CNVD-T is that its old. Most were manufactured around 10 years ago... With that in mind, its pretty decent for its age.
If image clarity is your main objective, almost all the modern commercial thermals will outperform it. (Anything 640, and most of the 320s)
The software, and sensors have improved dramatically over the past decade.
But the CNVD-T still has a few redeeming features.
- Clip On Capability - It can be used as a true clip on (3x sweet spot) or standalone optic
- Bomb Proof - It's rated to 50BMG. If you have a high recoil weapon, this could be your thermal
Heres my thoughts. As a 320x Thermal it preforms OK. If you can find one for $3,000-$4,000 I think that it offers a lot of performance at that price point. (Your giving up warranty, compared to a new commercial unit) but picking up Clip On Capability & Mil pedigree
Opinions my vary, I'm sure someone else will have a different perspective
