Product Information
Condition: Like New. The Ikelite 6812.81 Underwater TTL Housing for Nikon D810 DSLR is a clear polycarbonate housing built specifically for the Nikon D810 body, rated to 200 ft (60m), using Ikelite's Four Lock (FL) port system and a built-in TTL bulkhead connector for automatic exposure with compatible Ikelite DS-series strobes.
Who it is for
This housing is for a Nikon D810 shooter who wants TTL flash metering underwater instead of a slave-triggered strobe setup. The back-of-housing controls work as a remote for compatible Ikelite DS-series strobes, giving access to TTL exposure compensation and half-stop manual power adjustments without removing a hand from the housing. All important D810 camera functions are accessible through the housing, though no controls are provided for the Metering selector, Diopter Adjustment Control, or Flash pop-up button.
Key details
- Depth rating: 200 ft (60m)
- Weight: 6 lb (2.7 kg); dimensions 9.6 x 6.9 x 6.5 in (24 x 17 x 16.5 cm)
- Buoyancy: slightly negative in fresh water, varies with lens and port choice
- Port system: Four Lock (FL), with four locking latches for quick port changes
- Construction: special polycarbonate blend body with an aluminum tray and aluminum 1/4-20 threaded top mount
- TTL circuitry works with Ikelite DS50 (above serial 70000), DS51, DS125 (above serial 5000), DS160, DS161, and DS200 strobes; non-Ikelite strobes are supported in manual flash exposure only; the AF35 is not compatible
Compatibility and sizing
The housing is shaped specifically for the Nikon D810 DSLR body and accepts Four Lock (FL) system lens ports, sold separately. Two universal zoom gear sets are included: one for lenses up to 2.8 inches diameter and one for 2.8 to 3.0 inches, no lens modification required. The aluminum 1/4-20 top mount can be replaced with an optional vacuum valve for leak checking. Note that Ikelite has discontinued this 200FL/6812.81 housing and now offers the 200DL Underwater Housing for Nikon D810, which uses the newer Dry Lock (DL) port system and can be converted for use with legacy FL ports.

Frequently Asked Questions
How do I check an underwater housing's seal before a dive?
Before every dive, open the housing somewhere clean and dry, inspect and wipe the main o-ring and its groove, and close it with nothing trapped in the seal, because a single hair or grain of sand is enough to flood it. Confirm every latch is fully closed and that any vacuum or leak alarm reads correctly. Where you can, soak the sealed housing in a rinse tank or hang at the surface before descending, so a leak shows up before depth.
How do I care for housing o-rings?
Remove the main o-ring regularly with a plastic tool rather than anything metal, which can nick the groove, and clean both the o-ring and the groove with a lint-free cloth. Apply a thin film of the silicone grease the manufacturer specifies, since grease helps the o-ring seat and slide rather than sealing by itself, and a thick coat only collects grit. Replace o-rings on the schedule in the manual, or sooner if they look flattened, cut, or dry.
What do moisture alarms and desiccant packs do?
A moisture alarm is a sensor inside the housing that beeps or flashes when it detects water, giving you a chance to abort the dive before the camera is ruined. Desiccant packs absorb humidity in the air sealed inside the housing, which prevents the port fogging as you descend into cooler water. Neither replaces a proper seal check, since they provide early warning and fog control rather than leak prevention.
How deep can I take an underwater camera housing?
Only as deep as its rated depth, which the manufacturer sets and publishes in the specifications, and it should never be exceeded even briefly. Depth ratings assume a housing in good condition with intact seals, so worn o-rings or a damaged port reduce the real margin. If your diving might take you deeper, choose a housing rated comfortably beyond your planned maximum depth.
Can I use a phone housing for scuba diving?
Only if the housing is specifically rated for the depth you plan to dive, because many phone cases are splash- or snorkel-rated rather than scuba-rated. Touchscreens generally do not respond underwater, so a diving phone housing needs mechanical buttons or another control method. A phone's own water-resistance rating is not a substitute for a housing, and any housing still needs seal checks and o-ring care.
How do I rinse a camera housing after diving?
Soak the closed, sealed housing in fresh water and work every button and dial while it is submerged so salt does not dry inside the control shafts. Let it dry completely, especially around latches and seams, before you open it, since opening a wet housing drips water straight onto the camera. Avoid opening a housing on a wet, moving boat deck whenever you have the option to wait.
What should I do if my housing floods?
Get the housing out of the water and open it somewhere dry, then immediately remove the camera's battery and memory card, because leaving a battery in a wet camera does more damage than the water itself. Do not power the camera on to check whether it still works. Dry everything gently away from direct heat, get salt-water-exposed equipment to a repair technician promptly, and inspect the housing to find which seal failed before you dive it again.
Which strobes work in TTL mode with this housing?
TTL exposure works with the Ikelite DS50 (above serial 70000), DS51, DS125 (above serial 5000), DS160, DS161, and DS200 strobes through the housing's built-in bulkhead connector. Non-Ikelite strobes can still be used but only in manual flash exposure mode, and the Ikelite AF35 strobe is not compatible with this housing at all.
Is this Ikelite 200FL housing still in current production?
No. The manufacturer lists the 200FL/6812.81 housing for the Nikon D810 as out of stock and permanently out of production, replaced by the 200DL Underwater Housing for Nikon D810, which uses Ikelite's newer Dry Lock (DL) port system. The 200DL can be converted to accept legacy FL system ports if needed.
What zoom gear sizes come with this housing?
Two sets are included: one for zoom lenses up to 2.8 inches in diameter, and one for lenses 2.8 to 3.0 inches in diameter. Both install on the over-sized zoom knob without any modification to the lens itself.
Can I use non-Ikelite strobes with this housing?
Yes, but only in manual flash exposure mode rather than TTL. The housing's TTL circuitry is built specifically to communicate with compatible Ikelite DS-series strobes through its 5-pin bulkhead connector, so automatic TTL metering is limited to those Ikelite models.
