Two Tank Dives

[CD_in_Chitown]

Bad for a new diver with only 10-15 dives logged?

While I agree with Kim in the phrasing of two shore dives as a two tank day, it is just making two dives in a "session" much as you probably did in your ow class. My agency allows up to 3 dives a day to count as certification, and these are students. While most dive boats will drop you in and make sure you get a good hour or so SI before the next dive and hit the deep sight first, etc, it's still a good idea (chance to practice) to use the repetitive dive planning method of your choice (tables), and know where you're at with nitrogen.

I too referr to two tank dive to inform others as to the number of tanks they need to bring as we are planning on doing two dives. Often this does referr to a dive boat, but can be also used (as I do) for beach dives. Twin tanks on the other hand is a common term for two tankes used together on one dive. These tanks are joined together by a manifold allowing one regulator to function off both tanks.

it's funny, i never use the term "two-tank dive" when diving the springs around here
(my equivalent to shore-diving).

i always say, we're going to do two dives, or we're going to do three dives.

however, if someone said to me (referring to a spring trip), "it's a two-tank dive"
i would know what they meant.
