Field Density Altitude Compensator data card/slide rule

Here's a short review of the FDAC on 6mm-BR.

I've seen these before and have been wondering if it's worth getting one. The user guides (FDAC and Mil-Spec) give a good explanation of how to work out Density Altitude and one of the more usable estimation tables that I've seen.

Currently I think it is only available for .223, .308, 300 win mag and .338 so I'm not sure I'll be getting one just yet but if they bring out more calibres I may be interested.

You can try it on their website if you are interested in one.
