I found having OC trimix very helpful when starting CCR. MOD1 CCR qualified me to air deco 45m (TDI Air Dil Deco rEvo). Spent 50 hours on the unit building up to 30-40m air dil deco dives, then after 50 hours started adding trimix dil for dives between 30-45m this is when I really fell in love with diving CCR, spent the next 100 hours doing trimix dill deco dives between 30-50m, then doing MOD2 after around 150hrs on the unit.
 
IANTD instructors can offer a first CCR class to divers with NO deco training that takes them to 150ft/Adv Recreational Trimix. I know of two instructors who teach it as they talk about it on FB.

I know college kids that have unprotected sex with strangers they meet on Tinder every Friday night because they talk about it on Facebook.

Both sound silly.

Someone with OC trimix experience should be reasonably comfortable with the physical skills of managing multiple decompression bottles and holding stops as well as the mental skills of complex dive planning (including deco schedules, gas needs, etc) and for them, going into a first rebreather course that includes decompression may make sense.

Someone that has no decompression experience *may* be overwhelmed simply by being on the rebreather.

PERSONALLY, when I took my first MOD1 course I felt overwhelmed with all these buttons and gadgets all over the place on me while trying to figure out a few basics (my buoyancy was poopoo) for the first two days. My personal experience going into that class included over 1000 cave dives and OC deep trimix dives to 100m and I still felt overwhelmed at times. Thankfully I was able to get it together within a few days.

PERSONALLY, I tried to teach MOD1 with deco to a few people that lacked deco training/experience and it turned into a mess almost every single time. The only time I can think of where it worked out was with a student that worked as a recreational instructor in the keys. She literally works in the water for 2-4 dives a day, 5 days a week and had the comfort in the environment to be able to manage it after a few days.

I've also had several people that were AN/DP or Helitrox trained (single deco cylinder), but did not have a lot of experience with doing decompression diving and were pretty much seasonal divers. They struggled badly with that first class when adding in the deco part. For someone like that that wants a rebreather I would recommend doing the recreational rebreather path (100', no deco), gaining some experience, then upgrading to deco.

But hey, I also know a person that decided to compete in an iron man with no specific training. He got beat by the old nun that was out there training and practicing every day, but he survived.

Hi.
I do agree with you on that but you are in a place where, if I may say without being painted as a jerk :), there are a lot of alpha-type people who want to go too fast and do big dives.
I also was thinking that CCR were only for tech-deco-deep-wreck-cave-etc kinds of dives but there are some people who wants ccr for "rec" dives.
For those, there are, with IANTD for example, CCR-rec qualifications.
So maybe the MOD1, 2 and 3 need to be relabeled as "CCR tech 1, 2 and 3" :)
 
You spend your time reading about college kids sex life on Facebook?
Never too old to learn new tricks 😛

I didn't know anything about the site he mentioned until he did. I am missing so much fun being away from the US for this long.

The reality is the college kids aren't on Facebook. FB is for old goobers like me, the kids are all on the Gram and Tik Tok.

I don't view you as being a jerk. :) I think we're actually in agreement.

My argument is for going slow and gaining appropriate experience. If someone LACKS appropriate decompression experience (not just training, but experience), then I think they should go for a recreational non-deco CCR cert as that first choice rather than trying to make the transition to CCR and complete decompression training at the same time. While there may be an agency or two that allows combining deco training and CCR training, I personally think it's a mistake.

I do think CCR for recreational divers, for certain conditions, may make sense. Example, someone doing photography may find their wildlife encounters are significantly better by being on the loop, so there may be a bonus. However, generally speaking, I think someone making the leap to rebreathers should have some decent experience (and be quite comfortable) with OC deco diving.
