I have a Primos Blackout. Works great, it makes no glow flash or sound.
Just bought a Moultrie black flash today.
I do no use the IR cameras, as they will spoke deer. The red glow and flash runs them off, especially older bucks..
I have 2 white flash cuddebacks and they work fine. I gave been told the deer think the white flash is lightning. I do have several old bucks on those cameras.
As far as deer, we killed a 270lb 3.5 year old 8 point this morning on my families place on the Big Black.. Only 18.5 inches inside.
