| Arm Segments & Clamps ULTRALIGHT'S NEW BUOYANCY ARMS 2.5 TIMES MORE BUOYANT |
Large Buoyancy double ball arm segments were designed for the heavy Digital SLR housings and video housing.
They are 2" in diameter and constructed the same as the regular buoyancy arms.
They range in size from 8" to 16" in 2" increments to be able to add just the amount of buoyancy you need
to offset the weight of the housing and strobes or lights

With two arm lengths, 1 AC-CSB, 2 AC-CSF, and 1 strobe adapter and 1 base adapter these are the calculations:
You will need to add in the weight of your strobes underwater to these calculations to get you to the buoyancy you need.

The new style clamp (AC-CSB) is needed to put between the two new arms if you want the arms to come together.
This clamp weighs 1.3 oz more than the regular clamp.

An Ultralight arm generally consists of two arms segments and three clamps giving you the
greatest flexibility. Videographers sometimes use just one arm segment and two clamps. They do
not need the same amount of flexibility as a still photographer does.
The o-ring in the balls of the arms, base adapters, and strobe adapters eliminates the metal to
metal contact. This allows a much more linear clamping force, allowing you to control the arm
movement when used with small or large strobes even in varying current conditions.
The ball size of our arms and adapters is 1" or 25mm.

- Double ball arm segments
- DB-03 - very short arm, look like small dumbells, used for macro photography
- DB-05 - short arm, used for macro photography
- DB-08 - medium length arm, used for macro or wide angle photography
- DB-12 - long arm, used for wide angle photography
- DB-16 - very long arms, used for super wide angle photography
see weight and length page for combinations
Buoyancy double ball arm segments - were designed for users of heavy cameras
and housings. They are constructed of aluminum tubing with the ball ends press fit and
glued in. Air trapped inside allows them to be buoyant.

Single ball arm segments - allows you to use one less clamp in the arm set; but reduces
flexibility at the strobe head or base
Our most popular arm set consists of a base adapter, two 8” arms segments, three clamps, and a
strobe adapter. This arm set is used for both macro and wide angle photography

- SBDT-5 - Single ball 5” arm with a dovetail at the base. Will fit the BA-DB dovetail shoe
- SBNK-8 - Single ball 8” arm with a Nikonos SB 102,103,105 strobe adapter at the other end
- SBSS-8 - Single ball 8” arm with a Sea and Sea strobe adapter at the other end

Clamps - These clamps are what holds the system together and gives it flexibility.
Think of your own arms with the three joints and that is in essence what you have with your strobe arm.
