Halcyon TRAVELER, Owner'S Manual

To finalize the fit of the harness shoulder straps, loosen the 
straps enough to allow easy movement of the backplate. 
Position the backplate for  proper tank position, with the top 
of the backplate  high enough to touch by reaching behind 
your head with either hand; if you can touch the backplate, 
you should be able to reach  your valves when your rig is fully 
assembled (see image on the left).   With the backplate  in 
position, tighten up the arm straps until you are able to fit two 
or three fingers underneath the strap. You should be able to 
easily slide the straps off of either shoulder. Be careful not to 
leave excessive slack in the harness straps. An exceedingly 
loose- fitting harness will allow the backplate to ride low on 
your back, making it nearly impossible to reach your valves. 

The crotch strap should be comfortable and allow you to reach your tanks. The waist belt 
should fit as snug as is comfortable. Do not overtighten the waist belt so much as to restrict 
breathing. When adjusting the waist belt, make sure to set the buckle so that it is off to your 
right side. With the buckle in this position, the crotch strap is unable to accidentally open the 
buckle. The waist belt buckle (and/or another buckle) can be used to hold your primary light 
canister in place.

To adjust the crotch strap, buckle the waist strap without running it through the crotch strap. 
Now pull the crotch strap up to the waist belt. Set the length so that the top of the crotch strap 
loop extends a half-inch (12mm) over the top of the waist belt.

While standing on land, your BC should be snug but not uncomfortably tight. In the water your 
harness should be snug enough to prevent notable motion of the cylinder as you change orien-
tation, but not too tight so as to bind or restrict your complete range of shoulder and arm move-
ment.

FITTING YOUR BUOYANCY COMPENSATOR - CINCH QUICK-ADJUST DESIGN

Adjustment of the Secure Harness while wearing the Cinch is quick and easy. Following similar 
guidelines, begin your  first sizing in the exposure suit you will be diving in. Once finished, check 
placement of the D-rings as noted in the previous section and be sure to trim the extra webbing 
after you’ve determined the best size range for your Cinch harness and quick adjust crotch 
strap.

• 

To Tighten the Harness: While using both hands, grasp the ends of the waist band    

webbing and pull up and outward (at roughly 45 degrees) from the body.

• 

To Loosen the Harness: Grasp the webbing at the shoulder straps just above the waist.  

Push the harness out and up slightly from your waist.

Detailed information on sizing and adjustment of the Cinch design can be found  later in this 
text.
