MOUNTING AND ATTACHING FLASHES

Threaded holes are provided on top of the hand grips to accept the necessary shoes or bracket to accommodate your strobes arms. Additionally, three

1/4”-20 threaded holes on the bottom of the housing can also be used for various mounting applications and a 1/4”-20 threaded hole on top of the rear half

of the housing will accept an Aquatica bracket or Base Ball that can hold a focus/video light or a extra strobe arm.

Developed with the Aquatica housing in mind, the Aquatica TLC Strobe Arm System is highly recommended for its ruggedness, precision and the quality

of its craftsmanship.

USING WIRED CONNECTORS

If using an Aquatica AD800 Pro Digital housing setup with electrical strobe connections, these will

be connected to a switch board circuit that gives the users the option to choose between full manual

exposure or TTL (an external converter or single housed ash is required). Optional Ikelite bulkheads

connectors are also available.

When preparing the sync cord, be sure to lubricate the O-ring on the sync cord’s connector with a

light coat of the recommended O-ring lubricant for your strobe, Also advisable is to put a light coat

of O-ring lubricant on the threads of the connector, this help preventing corrosion built up on the

threads

Nikon Digital cameras are setup with a ash circuitry that only allows one iTTL ash to be connected directly to the camera, Nikon will not allow two TTL

ashes to be electrically connected directly, no matter if it is a Nikon ash or any other brand. The wireless approach preferred by Nikon prevents additional

ashes, or strobes from being connected directly to the camera, iTTL exposure will stop to function and a camera freeze is likely to happen. Two strobes

can be connected only if a TTL converter is interfaced between the camera and the strobe.

On your housing you will nd either one or two bulkhead connectors, the main connector (on right side) is wired through a switch board that can be congured

for full manual ash exposure or to be compliant with the latest TTL converter on the market. The secondary connector (left side if installed) is wired in a full

manual conguration and cannot be used for iTTL operation. By default you housing is delivered with the switch board set to full manual, if iTTL exposure

is desired then it can be made in either of two methods:

1) By using a single ash from Nikon or other brand (that is iTTL compatible with your camera) in a dedicated underwater housing connected with a TTL

cord to the main connector of your Aquatica housing.

2) By using an external iTTL converter connected to the main connector of your Aquatica housing, one or two underwater strobes with TTL cords, can then

be connected to this converter, (check with your dealer or the manufacturer to see if the strobes and converter are compatible).

Set up instruction for iTTL operation: Using the tip of a pen push all the switches to the ON (up) position, this will activate the connections on your main

bulkhead connector allowing TTL communication between the camera and the housed ash or iTTL converter.

Set up instruction for manual operation: All switches must be in the OFF (lower) position, in this case all iTTL connection are disabled and only the ground

and sync are left active, this will allow two under water strobes or housed ashes to be connected directly via the main and secondary bulkhead.

FOR OPTICAL CONNECTORS

The housing with optical connectors are supplied with one dual adapter for typical straight cord used by INON and various

strobe manufacturers and two Sea & Sea angled type cords adapter, select the desired connection and install on the optical

port base, tighten the set screw into place with the supplied hexagonal wrench.

In order to use Optical triggering, the built-in ash of the camera need to be in the up position, this can be done at time of

installation or later by pressing the ash actuator button (# 12) to release it.

If ambient light images need to be taken simply push the ash actuator lever (#8) to close the internal ash.

Note: it is advisable to turn the camera and external strobe off when travelling to your dive site in order to avoid useless

drain of the camera and strobes the batteries.

Field testing shows that mixing brands of optically triggered strobes is likely to give unreliable result and should be avoided.

Remember not to install the hot shoe if shooting optically triggered strobes (HYB version) as this hot shoe disengages the

internal built-in ash of the camera and prevent this later from working properly. Always do a few test exposures once you

nished setting up the strobes

Flash mode & exposure compensation:

When used with optical connectors: the lever will engage either the exposure compensation, selecting the corrective value

with the sub command knob(# 2) or the ash sync mode, selecting the required mode (rear sync, slow sync etc.) using the

main command knob (key # 3).

When using electrical connectors: This lever when pressed will engage either the exposure compensation, selecting the

value with the sub command knob(# 2) or the ash sync mode, selecting the required mode (rear sync, slow sync etc.)

using the main command knob (key # 3).
