Aaron gave me some filters to try so I will try those also. Reducing the viz light out of the back of the thermal is a good thing for several reasons: Messing with our night vision in our eyes, giving the critters some viz light against our bodies to spot, giving us headaches.
So, filters, reduced brightness, less intense pallets all can help. But, does this reduce detection ability? Yes, a bit, I think.
The BAE cores have a certain "wow" factor over the FLIR cores (at least the ones we can buy) ... this may be because of software priorities. BAE emphsizing terrain and FLIR emphasizing hot stuff (critters, bad guys, etc.)
But for me, the IRD Pallets, the 7 black and white pallets (3 white hot, 3 black hot and 1 edge detect) are wonderful. And I can easily give up the "LSD Trip" pallets in the FLIR cores. I run my IRD M3, 35mm, 2.5x, 640(60) on the black hot pallet just to the right of center most often and it is not intense gives a great view of the terrain and easy detection of critters in most cases. If I am not sure, I flip over to white and and check it out. The zoom is on the same menus item (#1) so I can quickly zoom also to increase ID ability.
But within the Armasights and ATNs the "red hot" and "sepia" pallets are interesting and can greatly reduce eye fatigue.
So what about reduced detection? There have been 2 times in 2 years, where the FLIR cores saw some thing the BAE cores did not. FLIR has an advantage in this department in my experience and due to their software priorities ... But if I could have just one thermal, it would have a BAE core.
