In Topic: WTB Aquatica vacuum system

Mrasette: I think that's a good call. IMO the LS is most useful to insure that you have integrity before you start the dive. Pump the housing down and let it sit for 5-10 minutes. I believe that the LS is of less value once the dive has started. That's why keeping the moisture detector is a good call. The moisture detector will pick up a few drops of leakage into the housing while the pressure in the housing will not have increased enough to trip the LS. But nothing will save you in the event of a catastrophic rupture.

I've used the Leak Sentinel for the past 3-4 years in an Aquatica D7000 housing. Here are numerous threads about it if you search a bit. Sold by Vivid Housings. Very happy with it. I removed the microphone and used that port. Vivid can provide adapters.


In Topic: Clear UV Filters - yay or nay?

Virtually all of the pros that I've shoot with on land recommend that UV or other clear filters not be used. I think that the same thinking would apply UW. I only use a UV filter when shooting is a dusty or sandy environment. Plus I carry a small (1") paint brush in my pocket to clean the lens frequently.

 

I also agree with undertow on using lens hoods. good protection with no negative impact on the image.


In Topic: D810 vs D7200

If you do buy the D500, the Nikon manual is not great. I'd suggest that you look at Thom Hogan's D500 manual (www.bythom.com). It contains far more depth and explanation than the Nikon manual. Thom is a recognized Nikon expert (and critic). I used his book to learn the D500 and get the settings correct for a recent trip to Africa (not UW). My UW rig is a D7000 and Aquatica housing. Probably good enough for me. I don't plan to take the D500 UW, but the focus system is amazing.

In Topic: Best Vacuum System for DSLR Housing

I've used the Leak Sentinel since they introduced version 3, I upgraded to version 4 a year or two ago and am quite pleased with it. Version 4 has temperature compensation and the ability to turn it off and not have to reset it later. I use it in an aquatica housing. I removed the external microphone, and installed the LS in that port. The manufacturer provides adapters for most housings. Before you decide I contact Vividhousings and confirm that they have an adapter for the housing you're considering. AFAIK you can use any vacuum pump as long as you have the small fitting that screws into the LS. Mine protrudes only about 1 to 1-1/2 inches from the housing and has never been an issue with fouling.

I have never tried any other vacuum system as I have been very pleased with the LS. When I first purchased mine, the pricing was far more attractive than either manufacturer installed or other third-party systems. I've not priced it lately to confirm if this is still true.
