Will do!

I assume this sort of gadget isn't affected if it gets a magnetic strip stuck on it so I can clip it to my scope tube? I know Rod's is held on magnetically ... I have no idea how these actually work or if anything in it can be affected by magnets. I only know there is so much metal in our building I cannot use a compass to line up so will have to go by visual sighting -hopefully using Polaris- to align everything.
