A refresher is a session in which divers are reintroduced, assisted by a certified diving instructor. This session should cover equipment review and knowledge enhancement. It differs from a "check dive" in which divers are asked to practice various skills and verify their weight. Divers need to take several refresher dives in order to keep up with current developments in the sport.
Basic scuba diving skills
You must learn how to use your regulator when learning scuba diving. You might need to take the regulator out to take photographs, or replace it if you lose it. You can either exhale or purge your regulator. You'll blow bubbles as the regulator leaves your mouth in either case.
Another key skill is to control your buoyancy. You need to take steady steps and keep your mind calm. There are many factors that can control buoyancy, such as your weight and where you are in relation to the water. You'll save more air if your buoyancy is controlled. It is vital to manage buoyancy to avoid any damage to corals or other marine habitats. You must ensure that your buddy is properly equipped for safety.
Scuba diving certification
There are several methods to become a certified scuba diver. All require that you learn basic skills and can perform open water dives. Depending on where you live, the ocean will probably be your first open water dive, but other large bodies of water, such as sinkholes or rivers, can be great choices as well. The next step in getting a scuba diving certification is deciding which courses you want to take and which ones you want to complete.
You can take the theory part of your scuba diving certification if you are based in Europe. This section of the course includes reading a manual and attending classroom classes. Or, if your home is in Thailand you can choose to take the course during the day or in the evenings. You can do your scuba dive certification at your own pace.
Get a refresher course in scuba diving
If you haven't been diving for a while, a refresher course in scuba diving may be a good option. This is a great way of getting back into the water and can be a cost effective way to refresh your skills. Refresher courses will cover all aspects of scuba diving including safety, equipment, and skills.
Refresher courses in shallow water are where professional divers instructors review the diver's skills and knowledge. They will help you with protocol and etiquette as well as correct weighting. These can be very helpful if you have difficulty with the smallest details. It can also help with weight problems.
