Housings $55.95

3.9/5 281 ratings

FitStill Waterproof Housing for Insta 360 X5, 40M Diving Depth

The FiTSTILL underwater housing is purpose-built for the Insta 360 X5, adding a waterproof shell, a thick silicone sealing ring, and an optical-glass lens element for underwater shooting.

A compact waterproof housing for DJI Action 5 Pro and compatible Action models, built around a tempered-glass lens and a quick-release mounting base. Buyers like the clear image quality and anti-fog performance for typical water sessions, with mixed durability or leak outcomes reported after deeper use.

4.2/5 31 ratings

Chasing Dory Underwater Drone - Palm-Sized 1080p Full HD Underwater Drone with Camera for Real Time Viewing (Purple)

The Chasing Dory is a palm-sized, tethered underwater drone that streams live video to your phone and lets you capture photos and video with a 1080p camera, plus dual LED headlights for closer subjects. It is best for people who want an easy “plug, dive, and play” underwater scout experience, but it is less ideal in debris-filled or murky water where visibility is limited and the virtual controls take a little getting used to.

The Chasing Dory is a palm-sized, app-controlled underwater drone for real-time viewing, photos, and videos.

It uses the ProShotCase app to let you control the iPhone camera with the phone’s volume buttons, and it includes a floating hand grip plus mounting support for GoPro-style accessories.

Housings $15.95

4.6/5 622 ratings

Sealife Moisture Muncher Capsules for SportDiver Underwater Housing for Smartphones (Orange)

SeaLife Moisture Muncher Capsules help reduce humidity in compatible SportDiver smartphone and SeaLife housing enclosures, which can help prevent fogging and corrosion.

Cameras $40.99

4.1/5 189 ratings

It combines a waterproof housing rating (up to 16.5 ft), a 2.8-inch LCD, FHD 1080p video, and an included 32GB card, but image quality is best viewed as “decent basics,” not smartphone-level. If you want a truly worry-free underwater experience, this is best for careful, supervised use, because waterproof reliability concerns have shown up in limited reviews.
