For any 320 core combined with a 35mm or 60mm lens, the FOV will be 1/2 that of what you will get with the 640 core and the same lens.
In other words the 640 core will double your FOV through the same lens.
That is a consideration in function, utility, and price because most of the time my thermal units are being used in their widest FOV mode possible (with least magnification) 98% of the time I am using the instruments in the woods.
Thoughts?
The area that you hunt (open fields , brush, swamps
) will dictate what you need. After using the thermals looking thru a rifle scope seems like looking thru a small tube. You really appreciate the fov that the thermals have.
Looked thru the photon 3.5x digital yesterday nice unit for the least expensive way to get into night hunting besides a just using a flashlight
. But the fov is just like any other 4x scope. After using the ls64 with 35mm lens the fov is much much larger and you can always use the e zoom to get a smaller fov even with loss of clarity still works for shot placement.
The smaller cores get the added benefit of a pseudo zoom due to having to be stretched to fit the LCD screen, you will not gain any clarity as this is a function of the core pitch and lens properties. But any larger sensor can be e zoomed in for the same view, as you zoom in the fov will shrink and look like the smaller core with at least the same clarity.I am working on adding a 3x lens to the ls64frankenthermal it should work for the ps24/32 as well.
