JCS8x6 Navy Dive Tables Card – Waterproof, Durable, Easy-to-Read Dive Planning Reference for Recreational and Technical Divers

This is a great product. While some may consider these table "out of date" they are great for helping to VERIFY and PLAN a dive ... in spite of the ubiquitous use of dive computers. Understanding the original USN dive tables and using them pre (and post) dive can help you validate that your dive computer is keeping you well within the golden standards of the USN tables. The product was made of durable plastic, was clearly legible and contains all of the dive tables within the normal dive limitations & handles repetitive dives (does not include USN "exceptional dives" which normal sport divers should not be diving in any case). Add to this the supplier was great in delivery & support. A great resource for you to have in your dive bag!

Perfect condition! These tables have been used and modified the world over for use in recreational diving. After some initial comparison, I've found that these tables are actually more conservative than PADI's RDP but a bit more liberal than NAUI's version. I would have no problem using these on any recreational dive.

The table is comprehensive, includes decompression dive. I only gave it 3 stars for 2 reasons:- The table is too big to really carry with you on/in your BC, they should have made it into 2 smaller slated instead of one large one- more importantly, the slate is very, very thin. The likelyhood of getting bent, folded or break is fairly high.In summary it is a good table to have in your dive bag (even there it is likely to get damaged) or on a dive boat, but practically speaking you cannot take it diving

I've been diving on the NAVY tables since 1993, when I got certified as a scientific scuba diver, and I taught scientific/rescue diving on the open coast from the beach for four years. I don't wear glasses, so I can't speak to the "small type" complaint. Seems ok to me. But maybe a waterproof 8x10 version would be better for some folks? I think this is a real nice form factor for the NAVY tables, which I keep with my dive log book.

Good for all divers to know the basis of how their dive computer works. Learning the dive table makes you a better diver

Outdated information.Don’t buy.You need Dive “air” Tables for updated NAUI cert!!!

Type is too small to be read easily, even with reading glasses.
