Specific models, such as the Sunroad D3 and D5, are professional diving computers that are entirely waterproof and capable of monitoring dives up to 50-100 meters. However, not all Sunroad watches are designed for diving. Always consult your device's instruction manual for its specific waterproof rating before submerging it.
In your watch's normal time mode, press and hold the 'Set' or 'Select' button to enter the general settings. Cycle through the settings to the unit menu, and use the up/down buttons to toggle the altitude unit from meters (m) to feet (ft), then press confirm to save.
