I have done several 160’ dives on air; no deco. We have a popular dive spot at 150. Absolutely if Doug salvage recovery they will use more technical dive techniques. Fortunately Pearl Harbor is not lacking for any type of ROV’s, DSRV, or hardhat divers.

Running that area yesterday in the charter boat the delta will be from 250 fathoms to 40 fathoms - the shelf is right on the reported area.
