Air horn could be for a nuisance bear on a portage who's trying to go after your food pack

I bought the jogger alarm because I'm a solo paddler and 2x portage.
I didn't like the idea of leaving my food pack unattended especially on long portages and hanging every portage would be a pain in the rear.
I put my jogger alarm in a secure side pocket of food pack and tie short line to branch and then pull pin cord on the alarm.
I figure if a bear grabs pack and the alarm blaring in his face fails to detour him, the pack will be easier to find in the woods. ;D

When in camp, I hang my food pack and take alarm in tent along side my bear spray.
I'd set alarm off as 1st response if bear comes into camp/ tent, then bear spray.
