One great way to make your waterproof fitness tracker work for you for a long time is rinsing it with clean, fresh water right after a swim in the pool or ocean. You see, chlorine and salt water, over time, can actually make the gaskets and seals that provide the water resistance feature deteriorate slowly without you even noticing. That said, avoid pressing the device's physical buttons while it is still underwater unless the company explicitly states that the buttons are designed for underwater use.
Check the strap and casing regularly for any tiny cracks to prevent moisture from reaching the internal electronics. It is good practice to keep your device in a cool, dry place when it is not in use, as this helps the battery and sensors stay in good condition for longer.

1. What is the difference between water-resistant and waterproof?
Water-resistant devices can only resist splashing or a bit of rain, whereas waterproof trackers are prepared for being submerged all the time at certain depths.
2. Can I use my fitness tracker in a hot tub or sauna?
Usually, it is best not to, because the heat and steam can make the seals expand, leading to moisture getting into the innermost parts of the device and causing damage.
3. Can these trackers be used in saltwater?
Yes, most of them are made to be used in the ocean; however, you have to rinse them really well afterward to keep the salt crystals from causing corrosion.
4. How does the tracker figure out that I am swimming?
The gadget relies on its built-in accelerometer and gyroscope to identify the regular motion patterns that are distinctive for different swimming strokes.
5. Is heart rate monitoring reliable underwater?
Even though today's sensors have improved significantly, they still encounter some difficulties; to get the most precise result, the band must be worn tightly against the wrist.
