As I understand it, a lot of Dive Shops "service" certain brands of gear. The only brand specific store on the island, however, is the Mares Lab at West End. The difference is that while getting my gear serviced at the Mares Lab, if a part needs to be replaced, they can do it there - no problem. And if the part in question needs replacing through no fault of my own, I do not have to pay for the part in question as long as I keep my warranty current by getting the annual servicing. Since I keep my (Mares) gear on Roatan and don't travel with it, it made sense for me to have Mares equipment/gear for the above reason. But again, that's just me.
