Great divers are safe divers, and safety begins long before you enter the water. Always dive with a buddy, plan your dive, and dive your plan. Check your gear thoroughly, watch your air and no-decompression limits, and ascend slowly with a safety stop on every dive. Stay within the limits of your training and call any dive that does not feel right. Learn the essential habits that experienced divers never skip, plus how good preparation turns every dive into a relaxed, confident adventure.
