Aren't you afraid that if you make a claim on your DSLR you won't be able to renew it for your drone. It's such an awesome policy I would hate to waste it on my DSLR.
A policy starts and ends. If the carrier chooses to write the policy again, they can make this offer. If a person makes a claim, the insurance company can choose not to write any new policy once the old one expires. There certainly is a good chance of this.
But what you suggest is getting a policy and then never making a claim when you have a loss. So you just want to pay the premium for, what amounts to, no coverage. If a person makes a claim and the insurance company does not renew the policy, then you walk away with paying $60 for a $1000 check. Certainly better then paying $60/year and never filing a claim.
