Scorkl Handheld Scuba Tank
It’s not quite as small or sleek as Bond’s breather in Thunderbolt, but the Scorkl Handheld Scuba Tank has the benefit of being real — and refillable. Scorkl’s basically a shrunk-down Scuba cylinder strapped to a breathe-on-demand regulator, with an integrated pressure gauge to tell you how much air is left. So bite down and dive in for up to ten minutes of air, with the feel of snorkelling without being limited to the water’s surface. Each includes a refill adapter which fits to a standard scuba tank to refill your Scorkl, or use the optional high-pressure hand pump to do it manually.
