The leash will keep the housing tethered to your wrist. This utility consists of a comfortable neoprene cuff with thick braided cord of approximately 50cm length.

For a manual white balance prior or during photography sessions, or as an incorruptible reference during postproduction, the grey-card from WhiBal simply does the job. The G7 is designed for low reflectivity, except that the sticker is intentionally highly reflective so that maximum TrueBlack Blackpoint level may be achieved by observing for maximum glare point. It is spectrally neutral, water- and scratch-proofed, and fits in a BCD pocket.

This shower-sized, 47 x 24 inch (120 x 60cm), packable towel made of antimicrobial nanofiber material is very lightweight at 5 oz (142 g), highly absorbent (it absorbs two to three times its own weight), and quick drying. It is suitable for drying and protecting underwater housings and related
gear, replacing the average shower towel, and even serves well as a warming wrap after a dive. The machine washable towel has a snap loop hanger and comes with a silicone travel case with carabiner.

Transfer progress, capacity, and remaining energy of the built-in battery can be monitored via the built-in status screen. To view and organise footage on set, Lacie offers its own BOSS app, which connects the mobile hard drive with iOS or Android mobile devices. The shock and waterproof SSD has a capacity of 1 TB, USB 3.1 connection, and a transfer speed of 430MB/s.

The strobe runs with four rechargeable AA-size batteries, has a maximum light power output of 150W, is made of machined aluminium, and has a built-in leak detector and 13 power settings, plus various user-programmable settings. Its beam angle is 130 degrees, and its colour temperature is 4900K. With a set of fully charged batteries, the Retra Flash PRO provides 150 flashes on 100 per cent light output.
A standard feature: The strobe can be triggered by optical cables, which are compatible with INON and Sea&Sea housings.

The Novus Plastic Polish Set from Ikelite is designed to remove scratches and abrasions from acrylic dome ports. The kit comes with three different
cleaning and polishing solutions for light scratches, heavy scratches, and for general cleaning. A cleaning cloth is included in the package.

The 100% waterproof Dive Label stickers are customizable (adding your own name and/or logo), are made from reflective sticker material and Ritrama brand vinyl, with added lamination to prevent scratching and damage. The labels are available in different colours and sizes.

With a weight of only 2,000 grams, dimensions of 46 x 38 x 24cm, durable Cordura material, and adjustable compartments and safety straps, the Easybag Trolley allows one to safely and comfortably transport a camera housing, ports and other gear as carry-on luggage. For usage as a ruck-
sack (shoulder straps are included), the trolley unit can be removed, which then reduces the weight by 800 grams. An extra pocket on the front of the trolley provides additional space for tablets, documents, or smaller accessories such as cables, O-rings, batteries, etc.

Spotting tiny critters might be an issue for aged eyes as well. Underwater housing manufacturer 10BAR has designed a flip-frame with corrective lenses (ranging from +/-3 to +/-5 in strength), which can be attached to most common diving masks. The flip-frame is made of anodised aluminium. In addition, it comes with two quarter-inch threads, which allow one to attach smaller accessories such as lights or action cams.

The ball mount comes in a standard 1-inch size, and, while still attached, allows the dive computer to be charged using the Shearwater charging sta-
tion. Using this ball mount makes all diving-related data visible right on top of the housing’s viewfinder. When the dive computer’s vibration alarm is activated, underwater photographers can “feel” the vibration notifications while still having their hands on the handles of the housing.
