Adjuster ®, the world's first automatic adjustable weight system for
scuba divers, developed at Think Tank Technologies Inc. by Joe Nicklo,
is a replacement for the conventional divers weight belts. The Attitude
Adjuster® allows ballast/weight repositioning to adjust to a SCUBA
diver's changing angle or attitude in the water. The Attitude Adjuster®
consists of two tubes that fasten lengthwise to the diver's air tank.
The tubes are
partially filled with lead shot that adjusts automatically with the divers
position. "Submarines have used this principle for years," Nicklo says.
"It's called movable ballast. If a submarine descends, ballast is moved
to the front. If the submarine ascends, ballast is moved to the rear."
Micro adjustments for attitude stabilization are obtained by momentarily
holding a desired position. The system also has an emergency jettison feature.
places the weights on the torso, the diver's center of buoyancy, instead
of around the waist. This change in weight placement gives divers more
control under water, he says, because they no longer have to fight the
tendency for the legs to drift downward because of the weight belt.
can be maintained with less effort," he says, "you conserve energy. And
conserved energy results in more efficient air consumption, which gives
all divers more of what they want more bottom time."
of the Attitude Adjuster® include comfort -- Nicklo's idea was sparked
by his wife's complaints of hips bruised by weight belts -- and a sea environment
protected from damage caused by diver's drift..
