I’m in full agreement with Greg and Green ... but I’m also wondering about the target of 165’. It’s not much deeper than 130’, so I’d ask if they have a particular target in mind? A particular wreck or something? Do they have other needs such as salvage or penetration training that need to be taken into account? It may not be enough for them to get trained to dive to 165’ to accomplish their goals, but they may not realize that yet.
