The beaches of Mexico are undoubtedly beautiful, but that beauty is not restricted solely to the land. The world below the surface of the water is also breathtaking, containing countless colorful fish, turtles, reefs, and even sharks. The best way to discover the wonders of marine life is scuba diving, but before strapping on an oxygen tank, divers in Mexico must be certified, which is a fairly straightforward process.

Scuba Diving Certification

Beginners must complete a basic level of training, which allows them to descend to certain depths, depending on weather conditions. Also, potential scuba divers need to be well-versed in the geography of the region to avoid getting lost.


Scuba diving certification requires an academic training session, a confined water session, an open water dive, and confidence. Though most beginners will opt for basic training in order to dive in open water, there are also certifications for rescue divers, first aid divers and dive masters. In Mexico, basic level divers are required to be physically healthy and somewhat athletic, as well as ten or older.

The Professional Association of Dive Instructor (PADI) Scuba Diver certification, which is recognized worldwide and valid for life, allows holders to dive to a maximum depth of 40 feet. PADI scuba divers are permitted to dive under direct supervision by a PADI professional, secure air fills, rent or purchase scuba equipment and take part in supervised dive activities.

Scuba Diving Safety

There are several tips for ensuring scuba diving safety. These include the following:

Don’t Hold Your Breath

Holding your breath underwater while scuba diving can cause serious injury or even death. Since the air in your lungs will expand during ascent and contract during descent, it is important to breathe naturally, since the excess air will escape. If a diver holds their breath, the air cannot escape as the lungs expand, which can result in the lung walls rupturing, which can be fatal.

Practice Ascending Safely

It is important to ascend safely. If a diver rises to the surface too quickly, the nitrogen absorbed into the bloodstream will be unable to dissolve as the pressure lowers on the way up. This can cause bubbles to form, which can lead to decompression sickness. Divers shouldn’t ascend at a rate faster than 30 feet per minute.

Stay Fit

Since diving is a physically demanding sport, it is important to be in shape. Divers must be able to endure long surface swims, dive in strong currents, carry gear and be exposed to extreme weather. Obesity, alcohol, smoking and exhaustion, as well as pre-existing conditions, such as the common cold, can all lead to decompression sickness.

According to diving expert Kevin Cocks, "Everybody can participate in scuba diving; we teach people in their 70’s to dive. A diver’s level of fitness is not as important as simply being in good health. Diving whilst taking medication to cover up a health issue is not advisable. A diver must always select dives and sites to fit their level of fitness and training. Do not dive beyond your comfort zone."

Double Check Your Gear

In order to scuba dive safely, your equipment must be in working order. Check both your own equipment, as well as your companion’s. Be sure to know how to release your integrated weights, deploy your DSMB, and where the dump valves are located on your BCD. If diving at night, ensure you have a fully charged flashlight, a backup and a chemical light, and if your taking part in a nitrox dive, calibrate your computer to your new air mix.

Don’t Exceed Your Limits

Each diver should be aware of their own limitations. If you feel unwell, mentally unable to face the challenge, or don’t trust the weather conditions, don’t dive.

"The risks for beginners and qualified divers is the same. It is the way that we apply our training that could put us risk while diving. Difficulties normally occur on or near the surface. Small diving problems become major problems due to the lack of experience and training. For example, PANIC is the biggest problem. Panic grows from stress, if the stress is not dealt with calmly and immediately, it becomes panic resulting in a divers uncontrollable urge to surface quickly. Ascending too fast can result in an air embolism, which is a medical emergency," says Cocks.

Plan Ahead

It is important to plan a dive ahead since it is easy to lose track of time, and find yourself low on air or into decompression. Check your gauges frequently and have an emergency plan in place before diving. Divers should also plan on using a third of their air supply for the descent, a third for the ascent, and a third as a safety reserve, in case you lose track of time or need to aid your diving companion.
