YOU NEED TO KILL THAT SPIDER ON YOUR LLIMB BOLT...

I would agree that it would be a good backup but I would be concerned with the accuracy.  One it would be hard to use with a bow attached but also the vibration from each shot would have to affect it over some time.  You can never have too many layers of safety so for me it would be a good backup.

Just my two cents.

3-Rivers has them for sale.

Thanks Bowwild, never thought of them.

I have one on wristwatch band and I always carry my GPS that I have tied a compass to with a length of rawhide.

The Nocking point, a sponsor here and great shipping....

Bow Compass $6.95

Batteries die. A good compass doesn't. Once you know how to use one, no need for anything else. GPS is great, but I would never let my life rely on something run by batteries  in freezing weather for any longer duration of time. When in northern Alberta just south of the North West Territories by myself, I'll take the compass.
My opinion, but no BS, it is an earned opinion.
