Burn,
Thanks for that good report about your experiences with the 4k. Apparently you have similar results that I do.
I can see an animal moving, but the body outline is somewhat degraded and tends to blend with the background. The body image is not distinct.
I have tried various lights. The current one I have been using is a TR-38 that I got from the UK. It has a powerful 850nm pill. I am thinking that maybe one of two things might be the cause. (1) The IR light sits in an adjustable ring that adjusts for windage and elevation. I have the main beam adjusted to point of aim. While there is not a bright splotch of light directly on the animal, it could be that the light needs to be adjusted so as to move the beam away from the point of aim a little. Perhaps that would give better contrast. (2) Perhaps the IR light itself is just too powerful and maybe the 4k is more sensitive to light that some other digital scopes.
I have a 940nm pill for the TR-38 that I plan to try. It is well known that a 940nm light is not as bright as an 850nm one and distance is cut significantly. However, since my bait site is only 60 yards it may work well. I won't know until I try it, which means I will have to go to the farm and stay at the cabin one night to test it. The only place I have at home to do any distance testing is in the woods behind my house, and that does not yield a good comparison due to the timber, whereas the area I hunt at the cabin bait site is open field with high grass behind the site.
I hope to be able to find just the right combination of light for the 4k because I really do like the scope otherwise.
Below are some photos to give you an idea of the terrain where I hunt. While there is some tall grass on both ends of the bait site, I don't think it is causing any reflection or problem with IR.
This is my little hobo shack of a cabin that I hunt out of. It is an 8x12 storage building converted into a hunting shack. It is insulated and heated and has a comfortable bunk.
This is a view from the cabin porch looking toward the bait site. This photo shows the field between the cabin and bait site
to be relatively clear of tall grass and brush.
This photo shows the area grown up more. The bait site is mowed between the two patches of taller grass / brush.
A dead coyote is lying at the upper end of the bait site, bordering the field. The bait site is 60 yards from the cabin.
