Nauticam NA 7DII Underwater Camera housing for Canon 7D MKII

Description

This is a Nauticam NA 7DII professional grade underwater housing for the Canon 7d MKII camera system.  I purchased it new and it has been cared for meticulously, including a complete overhaul in 2017 by Reef Photo.  Since then it has been used on four trips.  All controls work perfectly, and I am only selling because I am moving to a smaller, lighter camera system.
This housing, importantly, includes an optional Vacuum Leak Detection system.  This allows the user to check the housing for leaks BEFORE diving. It also includes a port cover, 2 O Rings, a tube of O-ring lubricant, a hex key set, and the original shipping box.
If you already own a Canon 7D MKII, this is a very economical way to move into underwater photography.  If you don't already own a MKII, there are many available at many price points here on Ebay.
Please note that you must also purchase at least one lens port to fit the lens you wish to use underwater to be able to use this system.  I have three ports for sale separately, one for the Canon 100mm macro lens, one for either the Canon 18-55 zoom lens or 60MM canon lens, and one for the Tokina 10-17mm wide angle zoom lens.  These are the three most popular lenses for this camera/housing system.  I will offer these ports at a fair price to whomever purchases this housing, or you can buy Nautimam ports used on Ebay or new from any Nauticam dealer.
I am happy to answer any questions you have about this sale.  Thanks

INCLUDES Integrated Vacuum Check and Leak Detection System
The Nauticam vacuum check and leak detection system is available with NA-7DMKII as standard equipment. Combined with an optional vacuum valve, this monitoring system provides constant updates on the water tight and safe to dive status of the housing. A simple coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur. The NA-7DMKII ships with a 3rd bulkhead port specifically for installing optional vacuum valves, leaving the user two other bulkhead ports for HDMI, sync cables and other accessories.
