I am good at shooting and bad at math :) There is another cheaper solution - Golf Rangefinders. They come cheap but have about 1000m max distance (some even 1500m). However, I think these laser rangefinders can be spotted on the field with an IR camera, so it can be tricky, right? On the other hand, there are GPS rangefinders, do you have any experience with them? Thank you for this lecture!
Nah, these are totally ineffective.
Laser rangefinders are where it's at.
I see. My second Q - can these laser rangefinders be spotted on the field?
You mean, is there a little dot on the target they are pointed at?
No, the laser is invisible to the eye generally, it's not at all like how the movies depict lasers; that's done for effect and in real life that doesn't happen. There's very specific equipment developed and used for various purposes, weapon-mounted laser rangefinders and other equipment made for military purposes, including rangefinders. These should not be confused with laser targeting systems that project a red (or green) dot as a sight. I have one of those and they are a different thing altogether.
No I mean if there is an IR camera or some other equipment that can see where this laser is coming from.
There's tech that will do that, yes.
As I thought, yes. Good old math and calculations are still the go-to for stealth I guess. But all these modernizations will defeat any human on the field, I guess. All the specters of vision are making it harder and harder to hide. Robowars here we come.
