SYSTEM OVERVIEW

1. Adjustable Harness (Figs. 1 & 2)

• The harness is adjustable to fit a large spectrum of body shapes and sizes.• (a) Four torso adjustments: Two front / Two rear - to accommodate various heights.• (b) Four waist adjustments: Two front / Two rear - to accommodate various girths.• (c) Single “Y” crotch strap to prevent the harness from riding up and maintain a more secure fit.• (d) All adjustment straps have web retainers to secure excess strap.

The Combat Swimmer Harness (CSH) is a harness system specifically designed for the SOF combat diver. The CSH integrates, simplifies and streamlines the wearing of underwater breathing apparatus (UBA), divers weights and mission specific gear.

Each weight pouch should be loaded with equal amounts of weight for optimum balance, preventing the tendency to roll to one side during the dive. Also, it is strongly recommended that each weight pouch is fully loaded with four separate weights for the 20 lb. pouch (load vertically). For example, if you want to load a 20 lb. pouch with 20 pounds, use four separate 5 pound weights.

SURELOCK™ WEIGHT SYSTEM PROCEDURES

Loading Weight into the SureLock™ Weight Pouches

Fig. 8

2. Loading the 20 lb. SureLock™ Pouch (Fig. 8)Lift up each pouch’s flap (a), and open far enough to insert weights. While holding the pouch fully open, insert the weight (vertically) and then close the flap. When each pouch has been loaded with weight, firmly run your hand over the flaps to securely fasten the hook & loop (b). ab

Load Weight Vertically

NOTE: The SureLock™ weight system features two interchangeable weight pouches which can be filled with either block weights or “soft weight” (pouches containing lead shot), in increments of 5 pounds or less. For ease of operation, low-profile block weight is strongly recommended.

Fig. 7

1. Weight Configuration - 20 lb. SureLock™ Pouch The 20 lb. SureLock™ weight pouch has a right and left weight compartment. Fill each pouch with four separate weights (two per compartment). If you need to partially fill the pouch, use the diagram (Fig. 7) for proper weight placement.

Installing the SureLock™ Weight Pouches

The SureLock™ pouches are installed with the plastic panel facing outward. To install either pouch, grasp the D-ring below the SureLock™ pocket with your opposite hand and slide the flap end of the pouch vertically into the opening of the pocket. Insert the male buckle (a) into the female receptacle (b) on the harness until you can hear/feel it “click” into place. Secure weight pouch handle with the handle retainer (c) (Figs. 9 & 10).

CAUTION: DO NOT attempt to don the CSH when it is fully loaded with weight. You may risk injury due to muscle strain or a temporary loss of balance.

Fig. 9

WARNING: Before every dive, it is important to 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 ascent, which could lead to serious injury or death due to arterial gas embolism, decompression sickness or drowning.

Releasing the SureLock™ Weight Pouches

Each weight pouch is connected to the harness independently of the other and must be released separately. This provides you with the option of being able to jettison one pouch at a time, thereby maintaining better control of your ascent rate in an emergency. In the event that you need to jettison weight, simply remove the weight handle retainer and pull the release handle of each pouch down towards your feet. When the pouch is completely disengaged from the pocket, hold it out and away from your body before dropping it (Fig. 11).

WARNING: Ensure that your weight pouches are not obstructed by the weight handle retainers, straps, lines, equipment, etc. Failure to ditch weight in an emergency may lead to serious injury or death due to drowning.

WARNING: To avoid injuring other divers, always look below you before dropping weight.

DONNING AND ADJUSTMENT PROCEDURES

1. To adjust the CSH, first put it on and connect all buckles. Ensure the yoke is positioned across the center of the back and equally distributed across the shoulders (Fig. 12). Check for areas needing adjustment.

2. Release the web retainers and unroll the rear torso adjustment straps. Hold the web retainer with one hand and adjust the 3-bar slide up or down to size the harness to the proper height (Fig. 13). Repeat process for other side. The lower belt should rest at the waist when the proper height is achieved.

3. Once the proper position is obtained, roll the strap around the web retainer until it is against the 3-bar slide and secure the hook/loop around the webbing (Fig. 14). Repeat process for other side.

4. Release the web retainers and unroll the front torso adjustment straps. Hold the inner webbing with one hand and lift up on the buckle to loosen or pull down on the outer webbing to tighten until the proper height is achieved. Repeat process for other side (Fig. 15). When properly set, the lower belt should rest on the waist.

5. Once the proper position is obtained, roll the strap around the web retainer until it is against the buckle and secure the hook/loop around the webbing (Fig. 16). Repeat process for other side.

6. Release the web retainers and unroll the rear waist adjustment straps. Hold the web retainer with one hand and adjust the 3-bar slide left or right to size the harness to the proper girth (Fig. 17). Ensure both sides are adjusted evenly. Roll the strap around the web retainer until it is against the 3-bar slide and secure the hook/loop around the webbing (Fig. 18). Repeat process for other side.

7. Release the web retainers, unroll both front upper and lower adjustment straps. Hold the inner webbing on one side of the front adjustment strap, with the other hand lift the right or left buckle to the side to loosen or pull the outer webbing to the side to tighten until the proper girth is achieved. Repeat process on both sides of upper and lower adjustment straps. Ensure the buckle remains centered when adjusting the straps (Fig. 19).

8. Once the proper position is obtained, roll the strap around the web retainer until it is against the buckle and secure the hook/loop around the webbing (Fig. 20). Repeat process on both sides of upper and lower adjustment straps.

9. The lower belt may be completely removed for front and rear adjustment. Remove the six snaps and hook/loop strap retainers to remove the belt completely for adjustment (Fig. 21). Reinstall when adjustment is complete.
