Texadillo....I don't rely on TID, just an option that is handy sometimes to ID empty .22 rimfire shells. I hunt a lot of old houses and abandoned one room school houses, torn down old churches etc. and I'll be darned if every kid didn't have a .22 rifle in those days. It gets overwhelming in some places, easy to ID on the Toltec 100... the needle doesn't even move on the meter and it saves my back.
Ha! Also wanted to say I agree with you about some of those "Old Dinosaurs"
detune is to zero in on a target when pin pointing, I don't use it to pin point don't think I use any pin point button on a Tesoro.
