For you all guys that are tired of writing your elevation adjustments for different stages on your arm only to have to come off the scope to read what was written on your arm, the Sidewinder is what you are looking for.  Checking your dope on an armband is wasted movement, which translates into wasted time, which we all would like more of when we are under the clock.  This is also great for you guys that like to keep your d.o.p.e. in a handy place on your rifle.
 

The Sidewinder Python D.O.P.E Card holder attaches to your rifle via an extended rubber coated wire instead of using patched of velcro.  The Python can mount to your rifle by wrapping it around your scope, scope rings, scope mount or other mounting location on your rifle.  It allows you to place your info for shooting a stage or your d.o.p.e. in a location that can easily be seen with your non dominate eye without ever needing to come off the scope/rifle.

The Python is pliable, so if you happen to knock it, it will not break.  Simply reposition it and it is as good as new.  It also folds out of the way for easy storage.

It was designed to run with standard business cards.  So if you don't like cutting your cards out, you can simply purchase some blank business cards and you are good to go.

The Sidewinder comes with 10 blank cards, and two pieces of velcro backed with adhesive to mount to your rifle.
