Now in a slimmer aluminum housing with a side-mounted dial and MicroSD for LUT/firmware updates.
4K HDMI input. 80m/266ft depth rating.
150 minutes at full brightness.
Dual 21700 batteries.
The KRM05 V3 is the next evolution of our professional 5.5″ underwater monitor — the same battle-proven 3000-nit IPS panel, now wrapped in a dramatically slimmer, lighter aluminum housing. We moved the adjustment dial to the side for easier access during dives. We added a rear MicroSD slot so you can update LUTs and firmware between dives without opening the housing.
Note: Set your camera's HDMI output to 1080p. The monitor accepts 4K input, but output must be 1080p for full functionality.
What's New in V3
Redesigned aluminum housing — slimmer, lighter, more compact than V2 while retaining the same depth rating
Side-mounted adjustment dial — easy one-handed operation underwater without reaching around the housing
MicroSD card slot — update LUTs and firmware quickly between dives, no computer connection needed
Same 3000 nit IPS panel, same monitoring tools, same 4K HDMI pass-through
