Hi guys,

I have been a CCR diver and Instructor for many years now I am looking at moving on to the all new HH or the Meg. I have emailed KJ and obtained a few points but is anyone out there who can help?

I am after a quality made CCR, also long duration!

A have a few mates with the Meg and it looks a robust unit, but I also like the HH.......

If only I had the money for both!

What I need are good points and bad (If any).

I wait in anticipation

Both units are as tough as they get, you could hit both cantisters with a bat and then go diving. I have seen and played with a HH and have hours on the meg..

I believe the HH to be the better choice for the following reasons:

1) The HH is built by a company that will be around fas long as they want to be.

2) The unit is more versatiole, you have the option to go with back mount lungs and then switch back, and use a CMF device.

3) Better design.

4) Huge scrubber (if im not mistaken and instructor didnt have to change the sorb during an entire class)

5) The business that built it never stands still, they always look for better way to make there product better and improve what they have implemented previous products.

6) Upgrades are very reasonably priced you you won't feel you've been gouged.

7) All known complaints are being improved.


Hope this helps,

Jon

Hi Jon

I dived the Meg now for 1½ years, with a few modifications I found it to be the best rebreather for me, and I can recommend it 100% You will not find a more robust and no nonsense unit on the marked.

If you have time, also take time to read the following post:

Hope you make the right choice

Nick,

A few more items of interest on the HH CCR that Jon didn't mention:

1. BOV as standard equipment
2. Diva HUD is a real treat!
3. HH electronics come with deco software as standard
4. Radial Scrubber
5. Very flexible design - eCCR/mCCR/backmount etc.
6. 4th cell holder as standard
7. Extremely sexy looking!

Regards,
Randy

Hi Everybody
To Mixaddict's replay I would like to add also that in HH (in comparison to Meg) handsets do not switch off during the dive, and this can give mental comfort to divers.

Talking about 4 cells - I don't think they are really needed - in case of connecting VR3 (because I guess you see advantage of 4th cell in this case) you can use any from three defoult cells which are available.

Cheers,

Hi

I think this information is incorrect, but I could be wrong. I was told that the newest version of the meg software allows the user to choose whether or not he/she wants the displays to stay active or enter sleep mode.

On the latest software the powersave mode is on by default but can be disabled so that the displays dont automatically shut down.. I can't speak for the v2.5 hardware but all the 2.0x hardware uses a power hungry dispay (significantly higher than similiar displays) battery time will be reduced.. I have not opened up the handsets of 2.5 hardware but they VISUALLY look the same..

for example the typical current draw is 15ma on the 2.0x hardware without the backlight active.. for comparison the HH dispay is under 2ma..

ok, I've checked this information.. and some sources say you are right - it should be available in 2.5 version.
sorry for creating confusion

Oh come on Joe... you cannot compare the 100-200 hours you get on the meg with the 3 hours you get on the HH
I know the price is more for the Meg batteries, but i have changed them 3 times since 2005.

Would like to say as well about having the displays go off. It is not such a bad thing, and it is not difficult to get them back on again. Just a click. The only reason i would see this as an issue would be when you have limited freedom of hands.

johnny it wasnt a negative comment, just that if you leave them on you will get shorter battery life.. if you measure the system in use the meg draws alot more current than the HH electronics.. Duration depends on the batteries and how much the solenoid and backlight is used.. and we all know that most meg divers fly their units manually (because of training) while most HH electronics users don't..

come one.. 3 hours is a safety suggestion so that you always have power in reserve and to try and cover duff cells out of the box.. Normally in warm water you can expect 6 hours+ out of a single AA (more if you fly manually).. if you compared that to 5 aa cells for the meg thats over 30 hours... Alkaline cells on a meg are more resistant to cold water because the batteries are in the loop and will be warmer than ambient water temperature..

I use 3.6v cells and on my last set I had OVER 40 hours (4 full CCR classes plus pleasure dives) of dive time (it was a mix of automatic and manual).. I don;t know the exact time since it was spread out over 3 different heads.. before the monitor and if I didn't have a vm handy, I would replace the cell between 15-20 hours of dive time (not bad for a $5 battery).. if I could test them I used them longer..
