My wife, 12 year old son, and I are new to diving. We are looking to begin our equipment collection and our instructor recommended beginning with the regulator. Any advice on nice starter regs for us
Wow, I'm surprised at how many are saying "exposure suit" to buy first. If I were you I would invest in a DIVE COMPUTER first, so much easier and so much safer to dive when you have a computer. You can go wrist or console (guess that depends on if you get a regulator too with or without air integration). A nice computer will set you back a several hundred bucks, Suuntos (D4/D6) are reputable but I've also heard bad things about their customer service. I have an Oceanic (OCS) because I love the dual algorithms and Oceanic in general is a good quality for a fair price.
Like all these guys are saying, I recommend trying out some different regulators so you know what you want. As far as brands go I would rate the best (in order) Apeks, Atomic, Scubapro. Of course this will vary on opinions but these are my "top 3." Another option is to join the local dive club (because you want to go diving a lot right!? ) and ask some of the guys in the club if you could try their reg. But when demoing, be consistent. Don't try a regulator at 60 feet and then compare it to one at 6 feet because they will be different.
Personally I rented the full unit (Reg, BC, cylinder and weights) for my first 3 years of diving. You can always rent a wetsuit but not always a dive computer. Thats my advice, hope it helps you!
