Question Can I expect big differences moving from Scubapro to Atomic?

Now now, gentlemen!

Nothing, nothing outbreathes an older D series Scubapro second stage (except their limited production predecessors) , the only stage in modern regulators that really matters much in connection with breathing ease. Atomics breath very nicely, but if you are upside down or face up examining the ceiling of a cave they run a poor second to a D400 or D350. I have one of each; they are indistinguishable in the water, and come the closest to effortless natural breathing, more than anything else I've tried, including a couple of Atomics. I don't think the new D reg has the same positional stability, but I have no experience with it.

This is very true. The Atomics are dry and easy breathing, and are pretty good at all underwater convolutions, but my d400 is amazing.

Sorry Doc but Bacchus was the Roman god of wine. @wetb4igetinthewater could probably tell you about Dionysius.

Oops

Yeah. Get a room.

As to the OP's question...the operative term is "big difference." I think it has been determined the answer is no. Please spend your money on diving or gear that you do need.

If only SB had a block button, so much bickering wouldn't take place.

Uh, oh! I sold my A700...

Of all my SP regs, I liked that one the least. Also sold mine.

Why specifically?

Why specifically?

That A700 hated me from day one. I never enjoyed breathing on it. I spent too much time trying to make it like me. Never succeeded. Guess I just like my G260s and B2s more.

Who serviced it? Same person as your other regs?

Edit: I could only find one local shop (Octopus Gardens in Port Townsend) that serviced my ScubaPro regs correctly.

Did the diaphragm vibrate at depth when breathing air? Did you ever use Trimix with the A700?
