DiveVolk Trays, Handles & Arms — Build Your Underwater Rig
A smartphone housing in the water without a proper support system is awkward to hold, difficult to stabilize for clean shots, and leaves no good way to attach lights. DiveVolk's tray, handle, and arm accessories solve all of this — they're the structural backbone that turns the SeaTouch housing into a proper underwater photography rig.
Everything in this collection is designed specifically for the DiveVolk SeaTouch 4 system and uses standard ¼"-20 thread and cold shoe connections that are also compatible with most major underwater photography accessories from other manufacturers. Build as simple or as elaborate a setup as your shooting demands.
The DiveVolk Tray & Mounting Range
Single Handle Tray
The Single Handle Tray is the starting point for anyone who wants more control over their SeaTouch housing underwater. It attaches to the housing's ¼"-20 base mount and provides a pistol-grip handle for one-handed operation, a cold shoe mount on top for accessories like lights or the SeaLink transmitter, and a stable shooting platform that dramatically reduces camera shake compared to holding the housing by its body. The grip design works comfortably with wetsuit gloves. A straightforward upgrade for any diver who wants steadier shots and an accessory mounting point.
Dual Handle
The Dual Handle provides two grip points — left and right — for two-handed operation of the SeaTouch housing. Adjustable handle width accommodates different housing sizes and personal preferences. Dual ¼"-20 screw mounts and dual ball head mounts on each side allow simultaneous attachment of two arms, two lights, or a combination of accessories. Ergonomic grips reduce hand fatigue during extended shooting sessions. Available in Black and Silver. This is the foundation for a fully rigged dual-light video or photography setup.
Float Arm
DiveVolk's Float Arm is buoyant — it reduces the overall weight and drag of the rig in the water, making it easier to maintain neutral position and reducing fatigue when shooting for extended periods. Available in two sizes: 447g buoyancy and 872g buoyancy. The lighter arm suits single-light setups where a small amount of positive buoyancy on the arm is helpful. The larger arm compensates for heavier video lights or dual-arm configurations where more buoyancy is needed to balance the rig. Both connect via standard ball joint to tray and light.
Flexible Arm (Cold Shoe Ball Head)
The Flexible Arm uses a cold shoe mount at one end and a ball head at the other, with a flexible goose-neck section that allows the attached accessory to be angled in any direction and held in position. Ideal for positioning a small light, the SeaLink transmitter, or other cold shoe accessories at a specific angle without needing a full rigid arm assembly. A practical, compact option for divers who want controlled accessory positioning without the bulk of a full arm system.
Expansion Clamp with 67mm Lens Adapter
The Expansion Clamp is the essential accessory bridge for SeaTouch 4 Max Plus users who want to attach lenses and filters. It clips to the housing and provides a 67mm thread opening directly in front of the phone's camera lens — allowing any 67mm-thread wet lens, filter, or dome port to be attached and removed between dives without tools. The Platinum housing has this adapter built in; the Max Plus requires the Expansion Clamp. Also available as the SeaTouch 4 Max Plus Expansion Clamp with 67mm Adapters (a version specifically designed for the Max Plus housing).
Building Your DiveVolk Rig — A Practical Guide
The simplest useful upgrade from a bare housing is the Single Handle Tray — it provides grip stability and a cold shoe mount for a light or the SeaLink. From there, the Dual Handle allows you to build symmetrically, adding float arms and lights on both sides for wide-angle video illumination. The Float Arm compensates for the weight of heavier SL120 or SL50 video lights, keeping the rig neutrally balanced in the water. The Flexible Arm handles smaller accessories that need specific angular positioning.
All DiveVolk trays and arms use standard ¼"-20 and cold shoe interfaces — the same connections used across underwater photography accessories from most other brands, including Bigblue arms and Sealife accessories. This means your DiveVolk tray can be combined with arms and lights from other brands in your existing kit.

Frequently Asked Questions — DiveVolk Trays & Mounts
Do I need a tray for the SeaTouch housing?
Not strictly — the housing can be used by itself. But a tray immediately improves control: the pistol grip of the Single Handle Tray provides a stable shooting platform and reduces camera shake significantly. If you want to attach any lights or accessories, a tray with a cold shoe or ¼"-20 mount is essential.
What is the difference between the Single and Dual Handle?
The Single Handle provides one grip and one accessory mount — practical for single-light setups and solo shooting. The Dual Handle provides two grips and multiple accessory mounting points on each side — it's the foundation for dual-light photography and videography rigs where balanced illumination from both sides of the housing is desired.
Which float arm size do I need?
The 447g float arm suits a single light of moderate weight (like the SL50). The 872g arm is better for a heavier light (like the SL120) or when using two accessories simultaneously. The goal is to offset the negative buoyancy of the light so the arm assembly sits neutrally in the water.
Do I need the Expansion Clamp for the SeaTouch 4 Max Plus?
Yes, if you want to attach any 67mm wet lens, filter, or dome port to the Max Plus housing. The Max Plus does not have a built-in lens adapter — the Expansion Clamp provides it. The Platinum housing has a built-in lens adapter ring and does not require the Expansion Clamp.
