Anybody heard of a hand held windage/Ballistics calulator? I currently use my smart phone with Strelok App. I have seen them on Shooting shows but can't find them online...gun)

A quick google search resulted in this:

explorer wind meter - Google Search

I like the Xplorer 4!

I would venture a guess, these are same ones used by Long Range Pursuits (Gunwerks) and Best of the West, with there own face plate on them.
