Buoyancy and Trim
The EX1R housing utilizes trim weights on the inside and bottom of the housing for
adjusting buoyancy and trim to your liking. In the basic configuration the housing uses
5.2 lb / 2.3 kg of trim weight, divided into one 11 oz weight (secured to the inside rear
shell, just to the right of the viewfinder), six 8 oz and seven 4 oz weights (secured to
the bottom of the housing).
The weights on the bottom can be removed for buoyancy adjustment or moved
forward/aft for trim. They can also be placed on the top accessory rails for further
adjustment. To do so simply loosen the thumbscrew and change the position of the
weight to the most suitable location. Be sure to tighten the trim weight snugly so it will
remain secure to the housing during use.
When adding lights, monitor or other accessory items the buoyancy / trim will change.
This requires removal of weight, and re-positioning for trim. This is a general guide for
amount to remove when using various accessory items:
