This setup has served me very well over the years.

Yes it's older and does not have some of the features of a newer camera. But it's a DSLR with instant shutter response and great focus lock. It's a fantastic way to get into an underwater DSLR setup for an outstanding price.

Always babied. Never flooded or damaged.

The Nauticam NA-600D housing includes four 1" ball adaptors (two on custom brackets) to mount lights, strobes, focus lights, go-pro, or other accessories. Includes extra o-rings and a custom foam tray that attaches to the bottom of the housing to achieve neutral buoyancy.

The Canon T3i DSLR provides the instant focus and response you would expect in a DSLR. I've included six extra batteries, two chargers, and a flash card
