Congratulations, Fluff on yours and your other half’s AOW certification.
I think you’re on track with the idea of getting more dives in at the local lake. If it’s too cold to dive in a wetsuit and a drysuit is out of reach (for whatever reason), look for a competitive pool with a deep end for competition diving. It’s not glamorous but it will fulfill its purpose of refining your procedures to confidently walk through the fundamental aspects of a dive from start to finish. That way, you fly to the Caymans confident and focused on enjoying your experience while learning new things in stride rather than getting stressed trying to stay caught up.
Regarding gear, I think
@Divectionist gave some really, really good advice but
@EberWolf followed up with great advice about restraint, also. You might consider prioritizing your gear purchases per the following - (1) Mask, booties and fins, (2) wetsuit, (3) computer, (4) BCD, (5) regulator set, (6) camera.
Each one of those equipment categories represents a doorway into a myriad of manufacturers and types of configurations (i.e, jacket style versus backplate and wing). One can easily suffer from analysis paralysis and get blown about by empassioned opinions here in the SB forums. You might consider looking at ScubaLab (
ScubaLab ) to help narrow down the choices. Well, at least it’s a start point to help you get educated on what the mainstream choices are thus allowing you to do further research at a shop and/or here on SB if you want something more specialized.
Regarding your computer, there is a new computer out that has an excellent price point and user-friendly size. You can find it here.....
Deep 6 Excursion Dive Computer. I bought one for my wife based on its simplicity, the algorithm it uses (Bühlmann - proven since 1965), the modest size and the sustained presence of the owners of the company here on SB. They are bombproof guys and committed in heart and mind to diving.
SCUBA is not a cheap activity; I have purchased several varieties of the same bit of kit to dial in what I like. Accept that you may buy something thinking you’ve hit a bullseye only to dive with it about 10 times and realize you should have bought something else.
Be very selective about your future instructors. Spend a lot of time on this...it will be worth it. Don’t chase cards or pledge your allegiance to an agency. Find a skilled instructor who will take the time to TRAIN you rather than just give you an orientation to the skill.
Good luck with the journey. Have fun and let us know how you and your other half get along.
