I personally thing my machine detects a tad better when the sun sets, due to radio interference, but Rudy does not think it helps. Cowboy and I think we get an extra inch, maybe it is our terrible soil that makes it so.
Yes there are a lot of things I like about it. Quiet, no distractions, no one to ask if you found anything.
People can't see you. I still don't like detecting if front of a lot of people. You kind of get used to it, but this is nice. I like to do it in total stealth as well.
I don't like to use a white light brighter than a propointer. White lights draw more attention to you than detecting in day. Psychologically they make people think you are a burglar, a la Watergate. A red light does not draw attention, because it is associated with break lights, cars, etc. Often I will use no light other than a propointer, and maybe flip on the red light when having trouble locating the coin, and only use the white light sparingly to see a date on a coin etc, when I am not moving around.
