For most underwater enthusiasts, the choice of a camera housing usually falls into two extremes: a basic, lightweight plastic shell that protects the gear but offers zero utility, or a massive, professional-grade aluminum rig that feels like carrying a piece of industrial machinery. While the former is portable, it leaves the diver guessing if their shot is in focus. The latter provides total control but often comes with a price tag and a weight that can make a dive feel more like a workout than an exploration.
AOI is attempting to carve out a middle ground. The company has announced two new additions to its lineup—the UH-GP HP and the UH-DJA6 HP—designed to bring professional-level monitoring and safety features to GoPro and DJI Osmo Action users without the prohibitive weight and cost of a full aluminum chassis.
These “HP” (High Performance) models are essentially a strategic pivot from the high-end UH-GPx “Signature Series.” By swapping aluminum for high-grade polycarbonate, AOI is targeting the “prosumer” diver—someone who needs the technical advantages of a large external monitor and extended power but doesn’t necessarily need the extreme depth ratings or the prestige of a metal housing.
Bridging the Gap from the Signature Series
To understand the value of the new HP line, one has to look at the UH-GPx. Developed in collaboration with professional cinematographer Kay Burn Lim, the UH-GPx was designed for high-stakes production. It is a formidable piece of kit, featuring a 5-inch Full HD monitor, a built-in power bank to combat the notorious battery drain of action cameras in cold water, and a Vacuum Analyzation & Wet Detection System (VWS).
However, the UH-GPx is not for the casual traveler. With a weight of 4.1 lbs (1,877g) and a retail price of $2,000, it is a significant investment in both money and buoyancy compensation. Its compatibility is limited to GoPro HERO9 through HERO13 models, making it a specialized tool for a specific ecosystem.
The new UH-GP HP and UH-DJA6 HP models retain the “brain” of the Signature Series—the monitor, the power bank, and the vacuum system—but strip away the heavy metal. This transition to polycarbonate is a pragmatic move. For the vast majority of recreational divers, the difference between a 60-meter depth rating (aluminum) and a 50-meter rating (polycarbonate) is negligible, as most dive computers and certification levels cap out well before those limits.
The Technical Edge: Why Vacuum Systems Matter
From a technical perspective, the most critical feature carried over to the HP line is the Vacuum Analyzation & Wet Detection System (VWS). For anyone who has ever experienced the heart-stopping moment of seeing a bubble escape a housing or, worse, finding a leak after a dive, the VWS is the primary selling point.
The system works by creating a vacuum inside the housing before the diver enters the water. A sensor continuously monitors this pressure; if the seal is compromised and the vacuum drops, the system alerts the user immediately. This transforms the housing from a passive box into an active safety device, allowing divers to verify the integrity of their seal on the boat deck rather than discovering a failure at 30 meters.
Coupled with the 5-inch Full HD monitor, the HP series solves the two biggest pain points of action camera diving: the “blind” shot and the “leaky” seal. Action cameras are designed for portability, which means their built-in screens are tiny and often washed out by sunlight or distorted by masks. Moving the interface to a larger, high-definition display allows for precise framing and real-time adjustment of exposure and white balance.
Comparing the AOI Professional Ecosystem
While AOI continues to offer the UH-ACT universal housing for those seeking a budget-friendly, basic entry point, the HP series positions itself as the “sweet spot” for serious hobbyists. The following table breaks down the primary distinctions between the heavy-duty Signature Series and the new HP variations.
| Feature | UH-GPx (Signature) | UH-GP HP / UH-DJA6 HP |
|---|---|---|
| Chassis Material | Aluminum | High-grade Polycarbonate |
| Depth Rating | 60 Meters (~200 ft) | 50 Meters (~165 ft) |
| Weight | 4.1 lbs (1,877g) | Reduced (TBD) |
| Key Tech | 5″ Monitor, VWS, Power Bank | 5″ Monitor, VWS, Power Bank |
| Price Point | $2,000 | Lower (TBD) |
Market Impact and Availability
The introduction of the UH-DJA6 HP is particularly noteworthy as it expands AOI’s high-end offerings to the DJI ecosystem. As DJI continues to challenge GoPro’s dominance in the action cam space, the availability of “pro-sumer” housings—those that offer more than a basic shell but less than a cinema rig—is becoming a key competitive battleground.
The main unknown remaining is the exact pricing. AOI has not yet released the specific retail figures for the HP line, though the move to polycarbonate almost certainly ensures a price point significantly lower than the $2,000 mark of the aluminum version. This makes the technology accessible to a wider range of dive photographers who have previously been forced to choose between a basic plastic case and an overpriced professional rig.
Divers interested in integrating these housings into their gear kits should contact authorized AOI dealers for specific pricing and regional availability, as these models are rolling out to distributors.
The next step for AOI will likely be the expansion of this “HP” philosophy to other camera systems or the introduction of updated accessory mounts to further reduce the overall footprint of the polycarbonate rigs. We expect more detailed pricing and shipping timelines to be released as the units hit retail shelves.
