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..

I usually get all week long on my HH. I do run manual but wont swear i never get "caught" by the solenoid. My dives are 2.5 to 3.5 of bottom time plus deco and sometimes, but not often twice a day.

I'm trained on the HH and Meg and would take the HH EVERY DAY over the meg.

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..

I don't think anyone could argue the displays aren't power hungry. Rather than faff around giving people the option to have the displays on all the time, it would have made more sense just to upgrade the handsets. Still, changing the batteries is hardly a big deal, and if you check the voltage before splashing it's hardly a safety issue. I've adjusted my Meg to take 9v alkaline dry cells from any convenience store, so even if I'm tinkering with kit at midnight I can pop over to the cornershop and get a new stash of batteries. Ultimately, I neet to get 2x 9v cells in parallel, but I haven't got round to it. It would really help if ISC put together a battery module that helps people load generally available batteries without the need for soldering. The present situation where people are paying international freight for custom battery packs is plain silly.

I don't understand the comment about 'peace of mind' from having the handsets on all the time. I instincively hit the Confirm button as I pull the handset towards my face, thus waking it up. If you're doing that every couple of minutes through every dive it soon gets into muscle memory.

I would not say its peace of mind, more convenience, the first trip to song Hong cave last year i was running the 2.01 software and with busy hands I found it a pain to keep pushing the activate button, to check the primary, and yes thats when you see the full benefit of the HUD.

On the second expedition I had the new software 2.05 and having the backlight on all the time was a great function when using scooters, with multiple tools, lights, reels etc that needed may hand all the time. It was nice just glance at the display.

Hey Nick:

You already know from our PMs which way I lean, having had both. Again, both are excellent units and you're not going to go wrong which ever way you end up going.

I did want to say don't worry about battery life when making your decision, though. The rumors I'm hearing are that both Leon and Kevin are about to announce solar panels on their handsets, for out-of-water operations, and "self-charging" handsets -- working much like "automatic" self-winding watches or those "self-charging" flashlights -- for under-water operations. It seems that these improvements are being driven by the increased energy consumption needs installing the IPOD into their handsets requires. And we already know by now that Kevin will give you the handsets in any color you want, so...

Wonderful times we live in. Now, if we could just get them to make the displays larger for us "have-to-wear-glasses" folk.

Nick - it's time to buy one of these excellent RBs and do that serious stuff you've been talking about. I'm going to see if I can talk my wife in to a trip to your part of the world and do some diving with you.

Regards,

Bill

Bill,

I wounder if a floating solar panel will be in order :-)

As for the diving down under anytime just let me know when you want to come. You could even come stay with Mrs T and myself?

Nick as I have said to you before within ECCR's their are now two generations of units,

Gen One ... Inspo Classics, Megs, Prisms etc, units with no smarts and

Gen Two ... Vision, Optima, Sentinal and HH .... Don't know were to put the MKVI just yet (gen two or three ??).

Go the HH mate far better unit. Gen two is the future the rest have been out dated.

regards Baz

Hi Nick ... as I said to you before, in

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

Nick

One consideration which is largely overlooked is the training. The quality and the availability.

You can buy the same unit just about anywhere and for around the same money but not the training.

Something to think about before parting with your money.

Regards,

Lance

Hi Nick ... as I said to you before, in

Without being to rude A MEG first gen what a load of rubbish!!!!!

Thought i better add to my first post,

The meg has very solid reliable electronic, great modular design, plenty of scrubber options, fantastic trim, and no thank you to built in deco, bells and whistles for serious diving.

That being said vibrating HUD would be nice.

It isn't if you go by electronic features as Bazza did.
Like it or not, the Meg has a setpoint controller and an independent, separate pO2 monitor.
The CCR1000 had that back in '69 ... better even, the 2ndary didn't need a power supply.
Oh yes, the HUD ... the MK16 had that back in the 80s ... that's 1st gen.

I doubt the current generation Hammerhead electronics are any less reliable than the current generation APECS electronics. They've been used for years to replace 1st gen electronics on the MK series, Inspirations etc.

The Hammerhead has the same, great modular design, as do many other rebreathers that have a stack in the center and tanks attached to it.

plenty of scrubber options

Axial and radial, in two sizes, right?
Who needs a choice of axial or radial? We already know how well radials perform since Steam Machines released their PRISM scrubbers and outperformed axials of the same size.

The Hammerhead offers two sizes radial, too. The larger one, we already know, last longer than the Meg's, no matter how Leon words it ... which seems to be the point of the large scrubber. On the smaller scrubbers, we don't know either Mini Meg's or Hobo's duration yet because neither test results have been published.

That has been said about the Hammerhead CCR, too.

Why? The Hammerhead offers deco on both primary and secondary display, so you have the data calculated by the actual loop pO2, without any extra gear to haul around.

Plus the option to add another cell for yet another deco computer for added redundancy, choice of o-t-s or rear-mounted counterlungs, choice of HUD display modes, choice of gas injection modes, etc.

It got that, too, as well as a BOV.

Stephan,

While I am very aware of all the Hammerheads features and copycat meg style, I am interested to know if you have owned and dived either and the above post is not based on marketing spec sheets,

I would also be interested to here from people with say over 100hrs on the hammerhead CCR without any electronic issues, as I have read quite a few post about issues on the HH electronic and not to many about Apecs problems

How many HH are now out in the field?

When I brought my first vision it was full of bugs Im now on my fourth electronic.

I have over 700 hrs on my meg and its only been to the factory once in 3 years for software upgrade, thats good going

I think I was more upset last night when I wrote the post that Bazza had categorized the MEG with a classic inspiration now based on bells and whistles and built in deco it may be true but absolutely not on the whole product, I currently own a few of these units and the best is bar far my Apecs meg.
