HydroHalo Device
Suction-mounted to the pool wall. Houses the brushless motor, spool, and battery. Variable-force resistance is controlled via the companion app.
Swimmer + Tether
Rubber-coated steel cable connects to a comfortable belt worn by the swimmer. The cable provides smooth, consistent force without the skin irritation of nylon rope.
Variable Resistance
Drag the slider to see how HydroHalo's variable force compares to a fixed-resistance system.
At low speeds, HydroHalo reduces force for warm-up efficiency.
Design Philosophy
How HydroHalo compares to existing solutions on the market.
Current Product
