How deep can you dive in swimming goggles?
If you dive the Technisub Aquasphere goggles (like a sphera mask without the nose pocket), and if you full inflate the goggle before going down, then it is possible to dive to 15-17m without equalizing the goggle. This can be nice since you have perfect vision and you have the fun of feeling the water around your nose.
Why do scuba masks cover nose?
Why do scuba divers wear masks that cover the nose and not just goggles? Goggles seem lighter and handier. The reason is that the nose pocket of a diving mask is needed to compensate for increasing pressure as you dive deeper. The nose pocket allows the diver to blow air into the mask, equalizing the pressure.
Can you dive without a mask?
Less distractions: Diving without a mask means you’ll have to close your eyes the entire time you’re underwater. Although this can be dangerous in rare occasions, the upside of this is you’ll save more mental energy. You won’t be looking around and thinking about things in your environment.
