Black Diamond Owner’s Manual Securing the BC to the Cylinder Note: BC cylinder bands adjust for all standard cylinder diameters: 6.9” (17.5 cm), 7.25” (18.5 cm), and 8.0” (20.3 cm). The cylinder bands are properly threaded to the buckles when the BC leaves the fac- tory.
Black Diamond Owner’s Manual TOP VIEW Threading the Cylinder Band Step 1. Firmly grasp the metal D-ring with your left hand. Step 2. While firmly holding the metal D-ring, rotate the buckle back towards the webbing. The buckle should form and angle with the metal D-ring as shown in the top view.
Double Cylinder Setup The Tank Band Kit for Double Cylinders (P/N 427042) allows mounting of double cylinders to all sizes of the Black Diamond. Please see mount- ing instruction provided with the kit. Before adapting your BC for use with double cylinders, it is important to...
For example, if you adjust the Black Diamond to fit over a T-shirt or bathing suit, it will be too small when you put it on while wear- ing a 7mm wetsuit or a drysuit.
Black Diamond Owner’s Manual Adjusting the Chest Strap The chest strap fits across your sternum and keeps the two shoulders from slipping to the sides, ensuring a comfortable and secure fit. Before donning the BC, loosen and disconnect the chest strap. After donning the BC, connect the chest strap and tighten by pulling on the free ends of the straps.
Black Diamond Owner’s Manual WEIGHT INTEGRATION FEATURES The Black Diamond features the SureLock™ (SL) weight system. With the SureLock™ system, weight pouches are secured with a mechani- cal locking mechanism, as opposed to a hook & loop attachment used on other models. The SureLock™ weight system either supplements or replaces a conventional weight belt.

Black Diamond Owner’s Manual Installing weight blocks into weight pouches. The weight pouch has an upper and lower weight compartment. For optimum balance, it is important that the weight is loaded correctly in each compartment. Use the diagram below (Fig. 10) for proper weight placement.
Black Diamond Owner’s Manual SureLock™ Weight Pouch Installation CAUTION: Aqua Lung/SeaQuest strongly recommends that you do not attempt to don your BC when it is fully loaded with weight. You may otherwise risk injury due to muscle strain or a temporary loss of balance.
Black Diamond Owner’s Manual WARNING: Before every dive, make sure each weight pouch is secure in order to prevent the pouches from falling out. Involuntary release of both weight pouches underwater can cause a sudden increase in buoyancy causing a rapid as- cent, which could lead to serious injury or death due to ar- terial gas embolism, decompression sickness, or drowning.
Black Diamond Owner’s Manual Non-Releasable Weight To supplement the releasable weight, the Black Diamond is designed to carry non-releaseable weight in two fixed pockets located on each side of the BC, between the harness and air bladder. Each pocket can hold up to 5 lbs/2.3 kg (10 lbs/4.6 kg total).
Black Diamond Owner’s Manual DONNING & ADJUSTMENT PROCEDURES Remove the weight pouches from the BC. Loosen and disconnect the chest buckle, waist buckle, and waist- band. Ensure that the swivel buckles on both torso straps are securely fastened. While firmly holding the torso strap where it connects to the BC lobe, fully extend each torso strap to its maximum length by pushing straight up on the slide buckle.
Black Diamond Owner’s Manual INFLATION METHODS Oral Inflation To orally inflate your BC, place your lips on the oral inflator mouthpiece (Fig. 16a) and exhale a small amount of air into the mouth- piece to purge any water that may still be in the housing.
Black Diamond Owner’s Manual WARNING: Do not rely on the power inflator as the only means to inflate your BC. It is important to practice the technique for orally inflating your BC so that you are pre- pared for any type of malfunction or out of air situation that could render the power inflator inoperable.
Overpressure Relief (OPR)/Dump Valves In addition to the overpressure relief (OPR) valve that is integrated into the dual valve, the Black Diamond has three other OPR/dump valves: Two are located at the bottom of the air bladder on the left and right hand sides (Fig.
Black Diamond Owner’s Manual SPECIAL FEATURES Knife Attachment The Black Diamond has two grommet holes located on the left pocket flap. These holes are designed to accept many of the specialty knives available from Deep See (Fig. 19). For information on available knife models, consult with your Aqua Lung/ SeaQuest/Deep See retailer.
Black Diamond Owner’s Manual PRE-DIVE INSPECTION Before each use, the BC must be given a thorough visual inspection and functional test. NEVER dive with a BC that shows signs of damage to its bladder or valves until it has received a complete inspection and service from an authorized dealer.
