    Thoughts on Freedom (Liberty) vs Shearwater (JJ/Revo/etc)

    For those of you have the Liberty or better yet have the Liberty and something else with a Shearwater, what are your thoughts between the two? Reliability, ease of use, ease to replace, etc?

    JJ? tried tested, works great, very few down sides except you need an aftermarket BOV

    Freedom? Recent unit waiting on feedback

    I only dove mCCR units with Shearwater, so can't comment on the controller.

    But the Liberty is fully integrated system with two independent controllers (duplicated solenoid control, deco calculations, etc..).
    Also has secondary method of PPO2 readouts (using He sensors), should Oxygen sensors fail.
    4 oxygen sensors
    2 helium sensors – patented
    2 methods of ppO₂ measurement
    2 independent computers
    2 solenoid valves
    4 displays

    I owned a Meg for 4 years with Predator S/W hooked to the head and Petrel 2 for Trimix or backup and now since 4 months a Liberty ..... it's so easy to use a Liberty vs Meg+S/W, it's also seafer because less manipulations for example to change sp or switch to BO. The liberty also is very compact and less volume to manage in a loop. Very easy to flush dil vs Meg and to do flush oxy is so quick vs Meg.
    I never go back to Meg
    Meg is very solid machine never had issue in 4 years and 250 hours but it's not user friendly, too much volume and too big.
    I prefer the Liberty so easy to setup the unit vs Meg or to unsetup the unit. Their customer service is very reactive and fast .
    With my Liberty I am a free diver on CCR

    CCR Liberty

    Prism Topaz, Inspo, P2

    Re: Thoughts on Freedom (Liberty) vs Shearwater (JJ/Revo/etc)

    Had Liberty a couple months now, coming from a Prism Topaz and P2. Liberty set up and check lists much more straight forward and quicker. It's mostly on the handsets. My analog P1 brain (grey matter between my ears) has adapted quite well to the Liberty/Freedom. Lots of neat features and simple to understand.

    Requires a Checklist = Too complex for recreational use stemming from poor design, end of. Walk away.

    Shearwater can be used without having ever picked one up before, intuitive menu structure stemming from good design, buy with confidence.

    Checklist is there to encourage pre-dive checks, as recommended by manufacturer and all training agencies.
    You can certainly just pick it up and use it. Menus are pretty clear.
    You can always switch the check list off if you wish.

    Fear of killing yourself, getting bent or making a tit of yourself in front of your peers should be sufficient impetuous to assemble and dive your CCR (or OC) correctly.

    Have seen too many divers Needing a physical check-list to get in the water (some of them safely...) it also breeds complacency- they begin to stop checking things not on the list.

    Common sense, quality basic training, good design and a safety mindset are what is required- check-lists breed by-the-numbers divers (generally speaking, there are always exceptions)


    (There is no legal requirement to having training as such it can never be cited a cause to do anything- the sooner agencies learn this the better, but that's a separate rant

    NLP stands for Neuro-Linguistic Programming
    The Map is Not the Territory. As human beings, we can never know reality. We can only know our perceptions of reality. We experience and respond to the world around us primarily through our sensory representational systems. It is our 'neuro-linguistic' maps of reality that determine how we behave and that give those behaviors meaning, not reality itself. It is generally not reality that limits us or empowers us, but rather our map of reality.
