Description
Kospet Tank M4 1.96 inch High Visibility Amoled Square Display Spec:
MULTIPLE DIVE MODES
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.
Free Dive Mode
Tracks depth, time, and temperature with surface interval monitoring
Scuba Dive Mode
Supports single-gas diving with NDL, safety, and decompression stops
Gauge Mode
Functions as a bottom timer showing dive time and depth.
Dive Alerts
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.
Oxygen Toxicity Management
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.
Decompression Management
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.
Safety Stop Reminders
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.
Equipped with Bühlmann ZHL-16C Decompression Algorithm
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.
