| Arm Length | Amount of buoyancy per arm length |
| 8" (DB-BL08) | 4.5 oz |
| 10" (DB-BL10) | 8 oz |
| 12" (DB-BL12) | 11 oz |
| 14" (DB-BL14 | 14.8 oz |
| 16" (DB-BL16) | 1 pound 2 oz. |
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.
| Arm lengths | Amount of Buoyancy with parts listed above |
| Two 8" | neutral |
| 8" & 10" | 1.75 oz |
| Two 10" | 7 oz |
| 10" & 12" | 8.3 oz |
| Two 12" | 11.2 oz |
| 12" & 14" | 15 oz. |
| Two 14" | 1 pound 3 oz |
| 14" & 16" |
1 pound 6 oz |
| Two 16" | 1 pound 9 oz. |
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.
Salt water is approximately 1.026X more dense than fresh water.
All these tests were done in fresh water

Shows the size difference between the original buoyancy arms
and the new ones and the new clamp and the old clamp





Will fit on any one of our parts on the neck under the ball.
Sorry will not work on the arms and adapters that Ikelite makes.


The AC-USLXL will take flashlights or lights up to 2" in diameter
The AC-TOSH will take flashlights or lights up to 1.5" in diameter

Ultralight's digital tray will work with this part. These mount bases have
two thumb screws that hold
their separate pieces together.
There are two pieces, the base plate that ties into the tray and the cameras
1/4-20 foot, and the
collar that goes around the lens port.
The rear thumb screw of the two that come with the dbase can be removed.
You will need to change the thick washer in the TR-D bolt and replace it with a thinner washer.
The AC-FB is used under the base adapters BA-AQ, BA-DB, and BA-TP at the
wide end, then a AD-1420 ball adapter
is attached at the narrower end, then a clamp and a spotting light holder.
The BA-FB is used on Equinox housings, the large hole under the knob on
the housing and then a AD-1420 ball adapter
is attached at the end with the smaller hole, then a clamp and a spotting
light holder.
The BA-FBd is used on our digital handle under the ball, allowing you to
put a AD-1420 ball on the other end
and then attach a clamp and spotting light holder.
This small 3 oz battery tester tests your batteries under load.
It computes the remaining power capacity using a 2-second pulse load test.
You'll have the confidence of knowing if your charging in a foreign country
has charged your batteries to
full capacity or how much power is left in your alkaline batteries.
Will test AA, AAA, C, D, NIMH or NiCd, alkaline, and 3 v photo lithium,
or 9v
Runs on 4 AAA batteries. This is a must have for your tool box at home or
abroad

The tray is TR-D, the handle is TR-DH, the spotting light
adapter is AC-SPL.

You can put one of the AD-TTLd on the right side (see below) if you have
second manual controller or just one of
our AD-3816 universal ball adapter to start your arm.
This is the new tray with a TTL adapter on the top of the handle to accomodate
the Ikelite TTL unit or it's manual sensor.

This is the double tray with two places to put your dual manual controllers
Taller version of the BA-IK, allows you to mount Ikelite's new Manual Controller
which can be utilized to provide 10 power
settings in half-stop increments or Ikelite's TTL slave sensor.
Allows for use of Sea and Sea's or Inon's fiber optic unit.
