Hi again Merv,
Dan’s link would be your best start… I do not have the Boltek lightning detector, too rich for my Boss’s blood, I am running the Hobby-Boards 1-wire lightning detector which has served our purposes very well…
I have to admit the Boltek units sure do seem very nice from what I have read and seen online, just cannot justify the expense for us as our main concern is being alerted to approaching lightning and severity which the hobby-boards solution does nicely at far - far less cost LOL
