1. Are you buying a new SCUBA diving mask? You can choose between a single-lens mask and a twin-lens mask. A single-lens mask gives the user uninterrupted sight and a clear broad perspective. The twin-lens mask on the other hand are more low volume and are easy to clear when water seeps in. At the same time, if you use glasses, the lenses of the twin-lens masks can be replaced to become graded to aid your vision.

2. Did you know that full tank of your SCUBA tank is 200 Bar or 3,000 PSI or Pounds per Square Inch? Make sure you check your SPG’s before diving!.

3. Did you know that the air inside your SCUBA tank is Compressed Air? In most cases other than times where there is any alteration made, the air inside your SCUBA tank will be comprised of 78 percent Nitrogen, 21 percent Oxygen, and 1 percent other gases. Therefore it is incorrect to say Oxygen Tank as pure Oxygen at depth can actually be toxic! Remember, your SCUBA tank is a Compressed Air Tank!
