The New Sidewinder Industries Heavy Duty Double Sided Python DOPE Card holder is an awesome solution to keeping your ballistic data right where you can see it easily, and without having to come off the rifle! When those seconds count, see your data come ups or holds in an instant and get those shots! It has a flexible arm that allows for many positions, and can't be harmed by banging into trees or barricades and such. The HDDS Python attaches on the rifle by wrapping around your scope or other creative locations.
The new updated Python HD Double holder has a clear plastic construction that allows you to put a dope card facing each way so you can have 2 quick reference cards easily available in one holder just by spinning it around. The all plastic is also a bit more weather proof and taller to cover the entire DOPE card as well for wet shooting conditions. It also incorporates a thicker Heavy Duty mounting piece that is more rigid and rugged than the single sided model.
The Python HDDS comes supplied with ten blank data cards, and they are standard business card size as well. You can also just insert a white card and use a dry/wet erase marker on the clear film layer. It cleans up with alcohol or hand sanitizer.
