Scuba is not a "uniform " sport! Caves, deep dives, wrecks, beach entrys all require different equipment.
The problem I see with a uniform set is there is no upgrading and no buying anything new the brand brings out. At some point it’s going to limit the shops income.
Same issue I have with DIR. Some DIR cop told me I should be wearing doubles on a shore entry, pained black I assume, not my wimpy st72
