The Mercury is a 5.9m dual zone swim spa with swim zone for exercise and a dedicated 42 jet spa zone for hot water hydrotherapy. Compared to the same-sized Hyperion model, it boasts 3HP rather than 2HP massage pumps for a superior spa experience and the swim zone is 30cm deeper, making it well-suited to adult swimmers. Complete with Galaxy’s inverter swimming system, the Mercury features four patented turbo jets and two variable pumps, allowing the swimmer to increase or decrease water pressure via 10 speed settings to suit ability or intensity preference, all while enjoying a powerful yet smooth continual flow of water.
