Home Forums Hunting & Shooting Backpack Hunting Piezo ignition - is it reliable in the mountains?

I've used piezo's at altitudes of up to 13k with no problems on my SP stove and am not aware of any reason it would be altitude dependent. From time-to-time I find I need to adjust to gap and location of the wire to keep it working reliably. Of course I always carry a lighter and matches as well just in case. A working piezo is a great convenience IMHE.
