SeaLife Cameras — Permanently Sealed, Genuinely Simple
SeaLife built its reputation on cameras that take the fear of flooding off the table entirely. The Micro series, beginning with the world's first permanently sealed underwater camera in 2014, eliminates O-rings and doors altogether — you charge it, you dive, you don't think about maintenance. That same simplicity philosophy runs through the entire camera lineup, designed so divers and snorkelers can learn the controls by handling the camera, not by working through a manual.
At DiveCatalog.com, we carry the current SeaLife camera lineup as an authorized dealer.
The SeaLife Camera Range
Micro 3.0 — The Flagship Sealed Camera
The Micro 3.0 uses a 16-megapixel Sony CMOS image sensor delivering both sharp stills and 4K ultra-high-definition video, with a built-in wide-angle 100° lens that lets you get close to subjects while keeping the full scene in frame. Three wide "Piano Key" buttons stay easy to locate and operate even with dive gloves on, and the Easy Setup feature walks you through optimal settings based on shooting environment, depth, and lighting accessories in use. Serious shooters get manual white balance adjustment and RAW format capture for post-dive editing. Battery life runs 3+ hours — a full day of diving — with 64GB of built-in storage for thousands of photos and hours of footage. WiFi sharing connects to the free SeaLife Micro 3+ app for wireless preview, download, and sharing.
Micro 3.0 Explorer Sets
Bundled configurations pair the Micro 3.0 with Sea Dragon lighting — from a single 2000F flood light through dual-light Duo configurations — giving you a complete, ready-to-dive imaging system rather than separately sourced components. The Limited Edition Explorer Set and Reef Edition (which adds a Wide Angle Dome Lens expanding shooting angle by over 40% and improving close-focus to just 5 inches) round out the bundled options.
ReefMaster RM-4K — Ultra-Compact Alternative
The ReefMaster RM-4K packs a 14-megapixel Panasonic CMOS sensor and genuine 4K video into a pocket-sized, easy-to-hold package, with a built-in fisheye lens for close-subject framing without losing the wider scene. A "Pressure Lock" thumb screw closing system applies optimal O-ring pressure for a reliable seal, and a Moisture Muncher drying agent prevents internal fogging. Expandable storage supports Micro SDHC cards up to 128GB, and a time-lapse function shoots at set intervals. Like the Micro series, it's built to pair directly with Sea Dragon constant LED lighting — no flash sync cables required.

Frequently Asked Questions — SeaLife Cameras
Why doesn't the Micro 3.0 use a strobe?
It's designed to pair with Sea Dragon constant LED lighting instead — you simply turn the light on and adjust intensity based on subject, conditions, and distance, with no flash sync cables or strobe triggers needed. This simplifies the entire shooting workflow considerably compared to a strobe-based system.
How much storage does the Micro 3.0 have?
64GB built in, enough to store thousands of photos and hours of video footage — no memory card to manage or lose, since storage is fixed and internal as part of the permanently sealed design.
What is the Wide Angle Dome Lens on the Reef Edition?
It's an add-on lens that expands the Micro 3.0's shooting angle by over 40% while allowing focus up to 3x closer (down to 5 inches), maintaining edge-to-edge sharpness for crisp, distortion-free wide-angle and reef photography.
Is the ReefMaster RM-4K as capable as the Micro 3.0?
The RM-4K offers genuine 4K video and a fisheye lens in an even more compact form, but the Micro 3.0 generally offers more advanced manual controls (RAW capture, manual white balance) and a higher resolution sensor for serious photographers — the RM-4K prioritizes ultra-compact simplicity.
