✨1L Scuba Tank Underwater Endurance Test: Effortlessly Master Your Dive Time✨
  1. Wondering how long this set with a 1L scuba tank  can keep you underwater? In normal use, it lasts about 20 minutes, more than enough for daily recreational dives. You can leisurely admire corals, chase small fish, and take underwater photos with friends.💡
  2. Actual duration varies among individuals. Steady and slow breathing allows you to stay longer. Rapid breathing or diving deeper than 5 meters may shorten the time, which is normal.⚠️
  3. We conducted tests in a standard environment at a water depth of 5 meters: Under a pressure of 200Pa, one can breathe stably about 75 times. The data is true and reliable. 🔒
