Leo3 Wi Universal Underwater housing

























We’re official suppliers for
The Leo 3 Wi underwater housing perfectly embodies Easydive’s vision: simple and robust design, advanced technology and maximum compatibility, for an ethical, sustainable and long-lasting underwater experience.
Launched in 2015, it was the world’s first universal underwater housing capable of managing commands via USB, infrared (IR) and Wi-Fi, making it compatible with a wide range of mirrorless and DSLR cameras, past, present and future.
The Leo 3 Wi is the most technologically advanced housing in the world, designed to accompany you over time, dive after dive, and it is the only housing in the world operational down to -150 meters.
Thanks to an intuitive interface and complete support, with digital manuals and video tutorials, it is easy to use even for those approaching underwater photography for the first time.
The Leo 3 Wi features an intelligent electronic control unit that automatically recognizes the inserted camera and activates the corresponding compatible controls. The same housing can be used with multiple camera bodies, even from different brands, making it a versatile and strategic solution for those who plan to upgrade their camera over time.
It is ideal for Sony mirrorless cameras, ensuring full access to all functions, but it is also perfectly compatible with numerous Panasonic, Olympus, Canon and Nikon models.
And if you change your camera in the future? With the “Programmer USB update adapter” and the “Leo3 Wi Camera Firmware and Centering Base” accessories, you can independently update the housing electronics, so you can continue using it with both your original and your new camera.
Choose the quality and reliability of a housing on the market for over 10 years, with the added benefit of worldwide direct support, even after purchase, and a lifetime warranty!

Ports and other accessories NOT included in the base version must be purchased separately. Images are for demonstration purposes only.
Main Features: housing made of anticorodal aluminum, CNC-machined from a solid block with 5-axis technology. This construction ensures maximum strength, reliability and wear resistance, even in extreme conditions. At the same time, this process allowed us to further reduce the housing’s weight without compromising performance, keeping it operational down to -150 meters.
Redesigned ergonomic handle: after numerous prototypes, we designed a grip that optimally replicates the natural hold of the camera. The result is an extremely ergonomic handle, with all commands easily accessible: 2 front trigger buttons and 9 on the back, including the switch button, which doubles the available functions.
Controls: managed by 11 wet-contact magnetic buttons, a technology developed and perfected by Easydive with over 20 years of experience.
Free of o-rings, these buttons are completely immune to leakage risks and are designed to work perfectly even at great depths. In case of wear or oxidation, they can be easily replaced. The 11 buttons allow quick access to all main shooting and camera management functions.
User interface: simple and intuitive. By connecting the camera via the supplied cables of the centering base, you can configure all functions following the manual or video tutorial.
Operating autonomy: the internal battery ensures about 14 hours of use. With some camera models, particularly Sony, the housing battery can power the camera directly, extending its autonomy from about 1 hour to 4–5 hours. This avoids the inconvenience of having to open the housing between dives to recharge the camera.
On/off control in water: the electronic unit allows easy power management during the dive. When the housing is turned off, the camera automatically goes into standby mode; to reactivate it, simply turn on the housing and press the shutter. For Sony cameras, power on/off is managed directly via the housing’s button.
Functions: standard functions are listed in the dedicated files for each camera, available in the “User Manuals” section. Other custom functions can be implemented upon request.
Remote reprogrammable electronics: if you want to use the housing with a new camera body, there’s no need to send it to Easydive: we handle everything remotely! Simply purchase the “Leo3 Wi Camera Firmware and Centering Base” and the “Programmer USB update adapter” accessories. Insert the new centering base specific to your camera, connect the USB key to the Leo3 Wi and power on the electronics: the update will run automatically. This way you can continue to use both cameras.
Simplicity: the only housing that lets you change shutter speed and aperture without taking your eye off the viewfinder.
Leak alarm: both audible and visual, with 4 flashing LEDs.
Depth: the only housing operational to -150 m, thanks to the double o-ring seal and wet-contact magnetic buttons that are unaffected by hydrostatic pressure. Deeper ratings available on request.
Universal: the only housing able to manage more than 100 different camera bodies of various brands and models, thanks to electronic recognition.
Handy: one of the most manageable housings for mirrorless and DSLR, with an almost neutral buoyancy in water.
Direct assistance: the only housing sold directly from the manufacturer to the consumer, ensuring maximum support before and after purchase. Wherever you are in the world, you deal directly with the people who built your housing: we assist you in the choice and continue to support you over the years, guaranteeing spare parts, maintenance service and constant assistance.
Warranty: the Leo3 Wi comes with a lifetime warranty.
