IMPORTANT SAFETY INFORMATION
DiveCore is a supplementary tool for trained, certified divers. It is not a substitute for proper training, dive tables or a backup dive computer. Always dive within the limits of your training and certification, follow your primary dive computer, and carry a redundant device. Diving carries inherent risks, including serious injury or death.
