Haha, that's quite a niche observation! A left-handed scuba diver might not be common, but imagining one "indicating a turn" underwater adds an extra layer of humor—do they signal with flair or stick to strict dive signals? Either way, it’s a quirky visual.
By the way, it’s interesting that while most scuba gear (like dive computers) is designed with right-handed users in mind, lefties often adapt seamlessly to underwater communication and gear handling. Props to them for navigating both the underwater world and a predominantly right-handed one!
