Safety Tips for Scuba Diving
Diving in Japan needs careful planning and strict safety rules. PADI Certification Japan helps ensure divers are ready for underwater adventures. It’s important for every diver to get a full medical check before diving.
Keeping an eye on your air tank is key for safety. Always check your air gauge and know how much air you have left. Dive Resorts Japan say it’s vital to ascend slowly to avoid sickness.
Travel insurance is often forgotten but it’s very important. Many divers don’t check if their insurance covers diving. Make sure your policy covers scuba diving fully. The risk of dying while diving is low, but being prepared can make it even safer.
The buddy system is a must for safety. Do a pre-dive check using the “BWRAF” method to avoid accidents. With 86% of diving deaths happening when alone, diving with a buddy is lifesaving.
Essential Gear and Equipment
Choosing the right gear is vital for safe diving. From regulators to dive computers, each piece is important. Always use high-quality, well-maintained equipment and keep learning about the latest safety methods.
Local Regulations
Japan has its own diving rules that change by area. Know the local depth limits (usually 40 meters for fun dives) and waiting times before flying (12-24 hours). Following these rules can greatly improve your diving safety.
