I was under the impression that I’d have to deal with getting the Fathom installed myself. It’s different if Kiss will install it at the factory if the Fathom is sent to them.

Did you ever end up deciding what direction you’re going to go?
OP
Yep. New Spirit.

OP, is it possible to take the class on a unit on loan from the instructor? This way you have a chance to assess whether you still want to buy the unit after spending six days on it and putting it through a few paces…

No and not exactly sure when I will.

Looking like I might be ordering my Spirit soon. Damned helium shortage. After some discussion today, instructor suggested I make the move to CCR now and go deeper after. Kiss has a 3-5 month lead time right now, depending on unit. We’ll have a longer discussion over the next few days.
ANDP and Normoxic is much more than going below 45m/165ft. It's very much about the planning of significant decompression dives plus the basic skills required to execute them.
Most of my Normoxic (60m/200ft) skills are used far shallower. For example doing 80 minutes on the bottom at 33ish metres (110ft) where a single decompression cylinder is insufficient.
I found the flexibility of being able to dive with smaller but more optimised decompression cylinders was the main benefit, e.g. two 7 litre cylinders rather than a single larger ali80 or two ali80s.
And the good news is that everything you learn for ANDP (with one deco cylinder) and Normoxic (with two deco cyliinders) is completely transferable to rebreather diving where you'll be taking one or two bailout cylinders and planning for the bailout ascents (which is pretty identical to ANDP/Normoxic planning).
Most CCR limitations are to do with the amount of open circuit gas you can carry. That's pure planning.
A note about MOD1: a lot of this is about stage cylinder handling. Every dive starts with a bailout test, so pull out the bailout reg, switch off the loop on to the bailout and breathe to test, switch back, put it away.
