SD Mount Cage for HERO3/3+/4. Protects GoPro® genuine dive housing and firmly holds attachment lens, arm, and flashlight. Dedicated "SD Mount Cage" protects GoPro® genuine dive housing from accidental damage and assures you secure attachment lens, arm and/or flashlight installation.

SD Mount supports speedy lens exchange

Equipped with INON "SD Mount" bayonet system. With "SD Mount", INON "UFL-G140 SD" underwater semi-fisheye conversion lens or "UCL-G165 SD" underwater wide close-up lens exclusively designed for an action camera like GoPro® camera, can be easily and securely mounted/detached underwater. Off course you can use the SD Mount Cage without any attachment lens.

When GoPro® camera is submerged, angle of view narrows down dramatically due to different refraction ratio between air and water (94°: HERO4/HERO3+ Black/HERO3 Black)making it difficult to benefit GoPro®’s ultra wide angle imaging. Also subjects in close range (within approx. 60cm/2ft in theory) are out of focus since GoPro® camera is a deep focus camera (fixed focal length) which prevents it from using for underwater macro imaging.

The INON "UFL-G140 SD" underwater semi-fisheye conversion lens provides nearly same wide coverage as using GoPro® camera standalone on land to enjoy capturing wild marine scene.

The INON "UCL-G165 SD" underwater wide close-up lens enables you to shoot subject from close range of the lens with deep depth of field thanks to GoPro®’s deep-focus characteristic.

Durable Aluminum Protector

Durable construction machined from an aluminum block protects combined housing even in rough condition.


The SD Mount Cage can hold INON "Direct Base III", "Z Joint" or "Z Adapter MV" at its top/bottom surface to install GoPro® camera on various systems for broad application. Packaged "Male Adapter (GoPro®)" can be attached on top/bottom of the cage to use GoPro® compatible accessories.


Besides INON "Grip Base D4", "D Holder" can be directly attached on the bottom of the SD Mount Cage. Two of "D Holder" can be installed on both sides at two different angles for steady and comfortable underwater imaging.

Tripod Shooting

The tripod screw hole (1/4 inch) on the bottom enables to use tripod/monopod.

LCD/Battery BacPac™ compatibility

The SD Mount Cage can accommodate with LCD Touch BackPac™, Battery BackPac™.
