Hello all,
I’m down in middle Georgia and ran a night time hog hunting business for years. In that time, I used both night vision and thermal.
Night Vision is rated Gen 1,2, and 3 and with 3 being the best but not all Gen 3s are the same. Heres how to know if you’re getting a good one but it’s kind of a long read so bear with me.
To rate NV you divide the FOM (figure of merit) by the SNR (signal to noise ratio).
Anytime that measurement comes to 64 or higher it is mathematically a Gen 3 scope. The problem is a scope with a SNR of 18 with a FOM of 1152 is technically Gen 3. But what about a scope with a SNR of 28? That would need a FOM of 1792 to equal 64 but would also be a Gen 3 device.
The quality difference in the 2 scopes above would be night and day ( see what I did) difference and if you had bought the one with a SNR of 18 you would be Upset especially if you looked through the other one. The one with the SNR of 18 would also require a IR Illuminator most of the time where the one with the SNR of 28 would seldom need one other than cloudy nights on a new moon except in things like corn stubble. But with the IR, you can get flashback that makes the scope too bright. A problem easily solved with a high end device by turning down the gain.
On thermal, I am not as well versed on the technical numbers that make one better than the other but as in most things you get what you pay for.
I prefer shooting with NV as it’s more “normal” looking but critters have a way of hiding and can be hard to see in corn stubble and brush like the many crp fields y’all have. NV is also a lot more durable imo but the quality scope are more $$$ than thermal now days. This has changed drastically in the last 10 years.
Thermal. You can’t hide from it. Total darkness, no moon, heavy corn stubble, you’re still going to shine like new money. It can be rough on batteries and does last significantly longer when using lithium batteries but those have been hard to find down here. It’s also a little more fragile than NV but most companies offer great warranties so that’s a moot point.
Good luck and happy hunting. Hunting critters at night is a blast.
