Isotta Underwater Smartphone Housing

Capture pro-level photos and 4K video underwater with full button control.

The Isotta Underwater Smartphone Housing is a precision-machined solution for divers who want full control of their phone at depth. This Isotta underwater housing combines an anodized red and black aluminum body with dual O-ring sealing, a detachable back, and a single-hand closing knob for secure, reliable operation. With a working depth of 100 meters and full mechanical control, it is designed for both recreational and advanced underwater imaging.

This universal Isotta housing supports any smartphone model on the market and provides both horizontal and vertical ergonomic handling—well suited for stills, video, or social media framing. Integrated Bluetooth control allows responsive shooting without requiring a dedicated app, while USB-C ports let you charge the housing’s battery or use it as a powerbank for your phone. A joystick, dedicated shutter/OK/back buttons, and optional lens mounts expand functionality for serious imaging use.
