DeltaWardog:In my introduction thread I was warned away from BCD/reg rental in Cozumel. Does anyone know the quality of Dive with Martin's rental gear? That's the shop we're considering for our trip, but want to make sure the gear is up to snuff. We can't afford to buy our own BCDs and regs just yet.
Have you emailed Dive With Martin and asked for information about their gear? Brands, models, if they have your size, how old the stuff is, etc? Find out what they offer then go to a local shop that carries the same lines and try the BCD on, check out the reg, etc. DWM has a good reputation. They've been around a long time and get lots of repeat business. If I was a new diver without any gear, the fact that they are reasonably priced, get consistently good reviews, and their packages include all the gear would make it very attractive and worthwhile to email or call them and ask some questions.
Renting gear from your LDS is all well and fine, but it's in no way a guarantee that the equipment will be 100% for the duration of your trip. Those of us who own our own gear know that even a just serviced reg can have issues, or a power inflator can stick, a buckle can break, etc. If you do decide to rent from an LDS just keep in mind that things can still go wrong and it will be up to you to deal with them while in Cozumel.
