Alright, I am in the process of getting certified right now (SSI, is this as good as the others?). I was wondering what the average cost for rental gear would be in the Michigan area, if that matters. I currently only have fins, mask, and snorkel. And what would I be looking at for a "nice" complete set of gear. I understande these are general questions but any input would be great. Thanks.
Alpha--
You're liable to get a lot of views on this. Doing a seach here for previous threads might be interesting for you.
My wife, son, and I all did PADI certifications. We're getting ready to get our daughter certified through SSI -- more convenient, geographically. The curricula and standards between agencies are standardized and practically identical -- some minor differences, but not significant.
After you're certified, the certifications of every legitimate agency (of which SSI is certainly one) will be recognized -- worldwide.
But the biggest differences are indeed between instructors themselves. There are good ones and not-so-good ones in all the agencies. If you have a good one, great. If not, well... You're going to be the best judge of that... how comfortable are you with your instructor; how demanding he/she is; does he/she make you practice and re-do skills if necessary until you get them right, or just wave their hand and say "oh, that's good enough;" and like that.
You've got the basic gear you need for the Open Water Diver course -- mask, fins, and snorkel. It seems to depend on where you are, but everything else you need during that course -- to include your open-water dives -- should be provided for you. But you should know that by now.
After that, rental can be expensive. The up-side is, you can get an idea of what you like and don't like before you buy. But pretty soon, you're going to be doing some serious cost-vs.-benefit analyses regarding renting vs. buying.
Buying ain't cheap, either. You're going to get as many opinions here as there are types and brands of equipment. (Do some more forum searches!) Sift through all the information, take all of it with a grain of salt, and start making your decisions slowly. You certainly don't have to -- and shouldn't -- buy all your gear at the same time. What you buy, and how much it costs, is going to depend in large measure on how/where you dive, and where you think you're heading in your diving.
You're gonna love it. Ask questions, and stand-by for more opinions from others!
