Also good to know. I had planned on having coverage from both the shop and my own PLI in all likelihood. Luckily I live in the smallest state so care mileage and fuel is pretty tepid at most. And there are only a few games in town as far as dive shops go (down to 2 for the state now) and within those, only a few instructors/DMs but a solid flow of requests for OW class assistants and requests for local dive leaders at local sites. And since we have more marinas than schools (probably) I can maybe supplement with dive services. I'm learning a lot of nuances I wouldn't have otherwise thought of.Yeah, I tend to agree. It might be possible to eke out a small profit, but it's really going to depend on the individual circumstances. If you have to drive far to get to dive sites or have to pay for lodging for open water weekends, that definitely eats into profits. Pools destroy neoprene, so that's another expense. Liability insurance is expensive, but some shops cover that. But at least with an LLC it is possible to claim legitimate expenses, shifting the balance a bit.
OP: I just thought of this - and you might already know it - but if your shop covers your insurance but you also take on extracurricular dive pro jobs that aren't sponsored by your shop, their insurance won't cover you. In that case you will need to have your own liability policy.
