They still show up as a current product at leupold.com ( http://www.leupold.com/hunting-shooting/accessories/tools-and-accessories/ )

I've used a couple of 'spud type' in the past and they worked well. I like the magnetic attachment better as it is simple and universal. The link above outlines how to use it at a somewhat high level.

I have no experience with the one you show but it appears to be a quality item and I'd expect it to do what you need.
