Oh, I see what he was asking - can you buy a pass "for two" and keep BOTH.

No; as was noted, the two people buying the pass have to be there, and they put the names of the divers ON the passes. Each diver then takes his/her pass.

You can subsequently use your pass without the buddy (e.g. its two separate passes that are issued), or with a different buddy, but that other person (if any) also needs a pass - either an annual or daily.

Think of it as a "two for one" sale, not a "two divers on one card" sale.
