    Given your location- get a JJ.

    Firstly its a more suitable rebreather for regular divers wanting to go diving rather than fiddle with buttons . Simple, rugged and adaptable.

    Secondly although historically more reliable you will be closer to the manufacturer if/when you need them.

    Thirdly- The waters are currently "muddy" regarding the Sentinels future, (do some searches online to see the sordid history)

    I Agree with Ben, the JJ would be a good choice in your area. I know there is already quite a few JJ divers in Norway already.

    Try contacting Jan Ødegaard from Nortechdiving in Kristiansand. He is a dealer and have the logistics and instructor contacts to give you the best possible course you can buy. As a bonus, Jan is a fantastic guy and you will feel welcome in his centre.

    Safe diving

    On paper the Sentinel looks great, in real life.... not so good! Just look at all second hand Sentinels that is priced ridiculous low.


    Where in Norway do you live?

    Defo the JJ

    Sentinal is too prone to breaking down, too big and too much of a hit on S/H resale value

    Of the two take the JJ unless you like wearing something the size of a bar fridge on your back!

    All i have reed say that the sentenil is a really good ccr, that it is big is ok.
    Is it a lot of problems with the sentenil?

    Is the jj suited for same type of divings as the sentenil.

    Yes


    Both are 100m rated units

    Both have been well past 100m

    The JJs not perfict but its the best of the present CCR available on the market (IMHO)

    I have owned a fair few of them and dived several others and the JJ ticks the boxes in terms of ease of diving reliabuility and transportation.

    It could be better at deeling with water ingress, it could be better at ease of cleaning and it is back to base if something goes wrong inside the potted head or controler unit, butr I can live with that because dispite my abuse it has kept on working.


    The rEvo is better in some respects, worse in others and it has the RMS system which is impressive

    The KISS expedition / sheerwater package is a big favorite of my own but it still needs a few bolt ons

    The Vision is a work horse and a bit of a lump to travel with

    The Meg is odd in some ways but a well built unit

    Thge Hammer head is a lump too but cleverly designed if only I could beleive its now reliable

    Sentinal is a big lump and aparently very prown to breaking down

    Optima is an odd one again Hammer Head electronics are debious

    All in all when I look arround at the competition I still think the JJ it right up there near or at the top.

    Saw my first JJ two months ago in NY and it looked awesome. If starting new I would get a JJ.
