Frequently Asked Questions
Is IP68 good enough for swimming in the ocean and pool?
IP68 means the device is dust-tight and can withstand immersion. For most pool and ocean swims IP68-rated rings are suitable, but you should rinse the ring with fresh water after saltwater exposure and avoid prolonged deep diving. Also confirm the manufacturer’s swim-mode features if you want lap counting or stroke detection.
Can a smart ring accurately track open-water swim distance?
Most rings don’t carry built-in GPS; open-water distance is typically estimated via a paired phone’s GPS or derived from motion algorithms. If mapping or precise GPS distance is essential, pair the ring with your phone or use a GPS swim watch instead.
How should I size a ring for swimming?
A snug, comfortable fit is key — it should not rotate or slide during turns. Use a sizing kit if provided (recommended by Milavan) and measure finger circumference after a warm shower when fingers are slightly larger. If between sizes, choose the tighter fit to avoid slippage in the water.
