Durability and Water Resistance
Built from corrosion-resistant stainless steel with a protective passivation layer, the dive watch withstands sweat and harsh environmental exposure such as seawater.
With a 10 ATM water resistance rating and over 20 military-grade certifications, it delivers reliable performance and lasting durability in any condition.
Support for Freediving Mode, Leisure Scuba Diving Mode (Single Gas), and Gauge Dive Mode.Across all dive modes, a diving watch measures depth and temperature with precision, records dive time, and logs every session automatically.
Tracks depth, time, and temperature with surface interval monitoring
Supports single-gas diving with NDL, safety, and decompression stops
Functions as a bottom timer showing dive time and depth.
This function notifies the diver when preset depth or time limits are exceeded. It helps maintain awareness underwater, prevents overexertion, and keeps every dive within safe limits.
The diver uses the watch to avoids oxygen toxicity risks by monitoring Central Nervous System (CNS) Toxicity and Oxygen Tolerance Unit (OTU). During the dive, oxygen exposure is monitored using CNS, keeping levels below 75%, and maintaining OTU values within the safe range of 100-200 OTUs, ensuring safer breathing at varying depths.
NDL: Non-Decompression Limit. NDL shows the divers how long they can safely stay at a certain depth. If they exceed this time, the risk of decompression sickness increases, acting as a reminder to stay within safe limits. DECO: Decompression. If the diver exceeds the NDL, the watch provides step-by-step guidance for decompression stops during ascent to ensure a safe return.
During ascent, the watch prompts the diver to perform a safety stop, allowing additional time for the gradual release of nitrogen from the body. This reduces the risk of decompression sickness and ensures a smoother, safer return to the surface.

The KOSPET watch in scuba diving mode uses the Bühlmann ZHL-16C decompression algorithm, which calculates gas absorption and release across multiple tissue compartments. This helps manage safe ascent profiles, preventing decompression sickness by ensuring precise and reliable dive plans within recreational depths of up to 40 meters.
· Diving is an activity that requires caution and professional preparation. The KOSPET TANK T4 & M4 are designed for underwater exploration enthusiasts and feature 10 ATM water resistance with the Bühlmann ZHL-16C decompression algorithm, providing reliable assistance during your exploration.
· For optimal performance and safety, we recommend using the device within 40 meters underwater. It is suitable for scuba diving training and recreational dives under safe depth limits, and best used by certified divers or those under professional supervision.
· While the watches supportdecompression management, divers should always observe the product’s depth and time limits, as individual physiological differences may still influence dive safety. Decompression sickness remains a potential risk with every dive.
· For safety assurance, always carry backup diving equipment such as a depth gauge, pressure gauge, and timer, and closely monitor air supply and dive profiles.
· Before each dive, verify all device settings and parameters, as the watches cannot predict or record data when not worn. Ultimately, divers are responsible for ensuring their own safety throughout every dive.
