Hi I am Tales Araujo. a diving is fairly easy to figure out what is: strap a tank on your back and breathe from it under water, and by default, you’re scuba diving. But remove the tank and things get a lot murkier, and often, terms like snorkeling, free diving, and skin diving is used interchangeably. Snorkeling is arguably the most popular activity of the bunch. Thousands and thousands of snorkelers take to the water every year on holidays or in their home waters. Snorkeling is defined as an activity where the participants use snorkel fins, a snorkel mask, snorkel, and possibly a buoyancy vest to help them remain afloat without strain. Now a days, many snorkelers also go for the full face snorkel option.
