The BC/automobile analogy is nearly flawless: Sedans and SUVs are reliable, all-around performers, but the specialty units — trucks, sports cars and hybrids — all hold a unique appeal. It's the same with jacket-style and back-inflation scuba BCs: Stable and loaded with features, they’re great for diving nearly anywhere. But frequent travelers might be seduced by sleeker models, and cold-water lovers will want beefier rigs. After test-driving a dozen BC designs, we’re convinced it’s a great time to upgrade or add a specialty model to your collection. The only limit might be the size of your garage. See our scuba gear reviews of these 12 models in the gallery below.
