Having looked into the Liberty very seriously next to the JJ (which I did buy), imo the Liberty helps the diver more than other units. It helps the diver a lot with electronics and software (checklists, monitoring, etc.). The downside, which steared me away from the Liberty, was that all that...

Yes, we do totally agree. However, if someone is not able to hold position, he or she should not even consider cave diving at all in my opinion. It's a waste of time and money because a good instructor won't let them pass anyway.

My advice is: get in the water and do everything. Hovering motionless is easy, hovering while doing things is hard. It doesn't matter what you do, using a reel, deploying an smb, laying down and picking up stages but do something. That's the skill you will need most. Being able to perform tasks...

Sure, they might (almost certain) give different deco values but that's not an issue diving a predetermined plan. They all do time and depth.

The question is: in what conditions will it be used? Low stress -> PETG, ABS, even PLA, etc. High stress and seawater -> engineering materials like Polycarbonate? The latter is very hard to print, but is one of the toughest materials to use. Many car parts are made of PC. There are lots of...

I do with 1,6 kg's with winter undersuit (BZ400). With summer undersuit alu of carbon plate and no weight and it's still heavy.

I probably would chat with them about their training en experience. Diving with a tank labled 'paintbaal' is not a 'no go' perse imo. A tank is just a tank, the content and safety (valve, breathing gas clean, etc.) of the tank is what counts.

In fact they die also after training and sometimes even during training. Training and certification in itself mean nothing. The most important aspect of training is understanding and mitigation of risks if you ask me. The card is just to get fills.

Don buy anything until you have actually seen and been diving the unit for a while. Comes with Petrel 3 computer. What I added after some 50 hours of diving and knowing what I wanted to change: - BOV Divesoft - Shearwater Nerd - O2 and dil transmitter - Extra 3 l tanks O2 and dil - Drysuit...

What you're actually saying imo is: the training is not worth the money because the instructor does'nt do his job right. I would agree with that. The majority of dive instructors should do a better job. It's hard to find a really good instructor not knowing anything about diving.

Seems you're very new to diving. Possibly you are overweighted and need to compensate with your BCD. I would say it's not uncommon to have a lot of water in your BCD considering your experience. My advice would be to try and shave of some weight gradually as your experience grows. You will...

I'am thought those skills in my MOD 2 class 2 years ago. It could be dependant on the instructor though. My instructor has been tech diving for more than 30 years with several types of rebreathers and did multi 100 meter plus dives. Anyhow, I'am glad I have learned those skills. I experienced...

My advice to your friend: get a high paying job, get self employed and rich or marry a rich wife. Otherwise, go freediving, forget about Tech diving :crafty: It takes a ton of courses, hundreds of dives and quite some dedicated dive vacations before even thinking about going CCR. CCR alone will...

For rec diving you can get away with that. For long tech dives? I would not recommend a wetsuit, but a dry suit any time. Maybe in the Philipines or somewhere like that you can get away with a wetsuit during long dives, not the Red Sea in my experience.

Agree. I had a complete mind shift about certification when I started my tech journey. I was very proud of my rec certifications and they are great to have, but they don't mean much when really going into tech. With tech it's not the certification that counts, but mastering the needed skills at...

The FX-CCR is so new there are hardly any divers around that have used it.

My take on your questions: I use my old and trsuty no name backplate wihout issues. I guess you can use the xDepp backplate as well (don't really know anything about them). Get the head protector. Otherwise, just sorb ans you'll be fine. Personally, I replaced the HUD with a Shearwater Nerd...

Same here. My solution is to open the valve after connecting the QC6. Can't connect with thick gloves in the water.

In my case it's right beside me. One grab is all I need to provide air. Personally I don't think there's much benefit having it tucked away under the loop.

No, that's not required. However, if you V-weights behind you backplate it can be usefull to take them apart. Less weight is always a good thing for me. I only use bolts, no washer etc. So there's only two bolts to release before the plate comes of.
