There are only 100 units made of the Ocean Crawler Decompression Timer DLC and all are stamped with a unique serial number out of a total of 100. How to use the Ocean Crawler's Decompression Timer? Check your depth by using four concentric indicator rings, each corresponding to a specific dive depth. To select your dive depth, refer to the scale at 12 o'clock. The depths are displayed in meters on the left (25/30/35/40) and in equivalent feet on the right (85/100/115/135). For example, if you plan to dive to 25 meters / 85 feet, use the corresponding ring, and if diving to 30 meters / 100 feet, use that ring, and so on, up to a maximum of 40 meters or 135 feet. Once you have determined your dive depth, the next step is to read the decompression times indicated in a circle around your chosen depth ring. Decompression time is relative to your total dive time; the longer the dive, the more decompression is required. The indicator will inform you of the required decompression stop duration based on how long you've been underwater. For instance, for a 25m-29m dive (first inner ring), decompression stops are indicated after 34 minutes. Therefore, for a dive duration of 35-40 minutes, a five-minute stop is required; for a dive duration of 41-50 minutes, a 20-minute stop is needed, and so on.
