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