Mechanical deer deterrent material longevity report

When I first started these deer deterrent experiments I was using a roll of aluminum flashing material to fabricate the primary clanging station.

I'm ready to conclude after a year and a half of testing that it's too thin to stand up to repeated use day after day. I would guess you can only expect somewhere around 6 to 9 months of constant use with this thin gauge of metal.

That's why I've upgraded to the next size thicker, which can be seen in the left and right photos above. You still get the metallic sound, but now you can measure longevity in years instead of months.
