Kraken Monitor - Ultra Bright 5.5” 4K V2 Underwater Monitor
The Kraken Ultra Bright 5.5” 4K V2 Underwater Monitor, also referred to as the Kraken 5.5" Underwater Monitor KR‑MON02 V2, is a professional-grade Kraken underwater viewing device designed for advanced underwater imaging. With IPS 4K LCD technology and 3000 nits brightness, it outperforms traditional monitoring tools, allowing videographers and camera operators to frame, focus, and expose accurately at depths to 80 m (266 ft).
Manufactured by Kraken Sports, this monitor integrates seamlessly with nuerous underwater housing systems, leveraging standard M16/M24 bulkheads and an included ball mount. Unlike standard housing monitors, it is self-contained, meaning it requires no external protective housing while underwater. Its rugged anodized-aluminum design ensures durability and reliability for the professional user.
Designed for compatibility with high-end cameras—such as RED Komodo or Canon EOS C70—the monitor enables 4K HDMI input and output (with optional SDI support at lower resolutions), while embedded video assist tools, including focus peaking, waveform, false color, histogram, audio meters, and LUT support, provide a full production suite for accurate monitoring.
Built to perform in challenging conditions, the monitor boasts light-sensing auto-dimming, fan-cooled LED backlighting, and a robust 4-hour runtime at peak brightness, powered by interchangeable Kraken lithium-ion batteries (compatible with Hydra lights). Weighing approximately 2.14 kg on land (0.56 kg underwater buoyant), it provides ergonomic balance and is easily mounted to your camera housing.
All critical specifications are detailed below.

What depth can the Kraken underwater monitor reach?
It’s rated to 80 m (266 ft) depth—safety-tested for professional dives. Exceeding this may void warranty.
How long does the battery last underwater?
At full brightness (3000 nits), expect approximately 4 hours of runtime per battery.
Can I use this with non Kraken housings?
Yes—compatibility via HDMI bulkheads (M16/M24). You'll just need a matching bulkhead port.
Is it easy to read in bright sunlight?
Absolutely—the 3000 nit IPS panel is designed for visibility even in direct sun glare, perfect for tropical dives
Does it record footage?
No. The monitor is a display device only. For recording, pair it with a recorder like Atomos Ninja series via HDMI.
