I just upgraded my system to a D810 and received my new D810 housing. I am planning on selling my d800 nauticam housing as I no longer will be using it. The housing is set up for fiberoptic strobs or ttl electric cables via a single electrical passthrough. The Vacum suytem shares the same passthrough. Housing works great and is in excellent condition, never flooded, used on about 4 trips. Probably has a few minor scratches. Comes with the handles, vacum pump, front port cover. Open to offers.
May also be willing to part with my D800E with about a 2.5 year mack warranty on it, if the price is right. I would then pick up a second d810 for back-up
