Unfortunately no....... After having the same insurer for probably 15 years I was forced to switch last year and I wasn't as diligent as I thought when choosing my new coverage. I forgot to check that little box for "collision" coverage so as my father would say, I'm ...-out. Comprehensive doesn't mean full coverage as the word would suggest, it covers only things like fire, flood, vandalism, deer, etc., things that are alive. Collision covers inanimate things like ice, guard rails, rollovers, other vehicles, etc.
If you have renters or homeowners insurance, your gear could be covered.
