Non of the options fit my case. I was certified in 2007 and since then I've been buying gear. In 2016 my daughter got certified and I also became instructor.
With the years I've got spare gear, I upgraded my reg, and miscellaneous items, some bargains, some gear I've got from friends that do not dive any longer. I cannot say that I have 2 sets of gear, but I have spares for several items. For example I have one wetsuit and one drysuit. Do I have 2 sets of thermal protection? perhaps.
My daughter has some own gear, like fins, mask, gloves, boots lights. She uses part of the spare gear I have, like reg and BCD.
