First Two dives on the Hammer Head

Mdemon

Hear bloody hear!

When you spend huge amounts of cash on life support equipment, it should just work! All you should need to do is then check it is doing so every now and then.

Yes, remaining cynical is fine and probably healthy when it comes to these things, but as a customer, I expect the equipment to live up to expectations.

My relationship with my Inspo is that it just works. I just make sure it keeps doing so. Mark has every right to want his HH/HUD etc to do what it should.

By the way, Mark, there are two Inspo heads for sale I hear... HH's always do well on ebay...

[quote=decoweenie]Mark,

True, but the question is why not. I paid £23,000 for my car and it has a system on it that monitors the rotational speed of each wheel and the direction of the steering wheel the chosen gear, the throttle position and the slip ratio of the diff. It then applies power to the wheel with the most grip and breaks each wheel individually to prevent spin whilst adjusting throttle position remote from the driver input and selects the slip ratio of the diff to give you the best punch out of the corner.

And you get a free car with it with a radio and air con and everything

I never turn of the DSC and drive it "manually"

My £6000 CCR has to monitor the ppo2 of the gas in the unit and inject a bit more to bring it up to set point.

I really don't think its too much to ask that it does this properly without any input from me. If I didn't want / trust the electronics to do their job I'd have got a £2500 kiss and just run it manually. Getting a £6000 eccr and running it in parachute mode all the time seems a total waste of money to me, but others have said the same for VR3's and my HUD so each to their own.



Before I even loaded the car I knew my gas I knew my SAC and I knew my depth. I could tell you what my gas was based on my calculated 15lpm sac at any point in the dive without looking at the gage. My actual sac of around 12 would put a pretty good safety margin on it. The only thing that could spoil the day is a large gas leak. Which I would notice or my buddy would. The gage only came useful if something went wrong. I didn't even bother using a gage on my shallow deco mix.

I wonder how many CCR divers regularly check their dill and 02 contents gages through the course of a dive?

Hmmmmm now now... let's not go HH bashing... a simple scan of this list show the number of Inspo heads both Classic and Vision that have had their own issues.....

As a former US President said wisely said... "Trust but verify..."

Dive Safe...

Yes an lets remember WHY I got a HH in the first place. Because, I had a non functional Insp head, thats why. And why haven't I got a Vision? because i am still waiting for them to get all the bugs out of that as well. And why not a Meg? they haven't got the Apex III head on the market yet let alone dealt with any bugs, and so the story goes on unit to unit. Do the KISS hand sets still leak like sieves?

All the CCRs on the market are flawed. There just isn't the financial potential to support detailed R&D so we are the Guinea pigs.

Hi,

Not just bashing the HH, I assure you. ALL CCR equipment should be fit for purpose. As an Inspo owner myself, I have had a few of those "issues"...

Wow, I never expected this to become such a controversial thread. All I can say is that I have in fact allowed the controller to handle the set point in the past. I also occasionally let it fire a few times during the dive as a means of verifying that it is working properly. Of course, I also do this prior to every dive when running my pre-dive checks.

Why I prefer setting it at the lower end of the range, controlling the gas injection manually, I can't say. I just do. I like having the precision control based upon my anticipated moves, and I find doing it this way is more efficient for me. So, I set it like this, and I add gas as needed.

My instructor, Tom Mount, also mentioned that he does the same thing. However, I don't do this just because he does it. In fact, the only reason I even found out that he does it this way came up quite casually. It was only after I mentioned to him that I prefer it this way (somewhere during the end of our training) that he responded that he does, too.

As far as cross checking goes, in my training, I was told that I would have to write "I will check my hand sets not less than every four minutes" 100 times if I did not check at least that often. I believe in my training. So, I continue to follow it even without having my instructor on top of me about it now that I am out in the real world.

When on open circuit, the frequency of check was based on depth. So, I could see checking infrequently on shallow recreational dives while on a large set of doubles. However, on a deeper dive, I would give a quick check every five minutes or so. I would check more frequently as I neared turn pressure.

Yes, I even check my gas gauges on my CCR even though I know I have way more than enough gas for a given dive. I do this because I am trying to internalize just how much gas I use with my new toy. Second, this is a great way to monitor for gas leaks and such. Usually, I only check a few times during the dive since the consumption is so little.

I am a big believer on following the same protocol for all dives so that I can do the same thing on the more challenging runs by habit rather than having to concentrate on remembering to do them. If you always do the same thing in the same way, I think that it reduces the chances of forgetting to do something when it really counts.

I am just a . However, I am trying to learn good habits at the early stage. So, it is entirely possible that you more experienced users know something that I don't know yet. I am listening to everything that you say, and watching everything that you do. Thanks for your help during the learning curve.

I don't understand what does "keeping schtum" mean, so will assume "keeping quiet" ?

Regardless, I don't remember saying too much of anything about CCR cave since I haven't cave dive for the last 3 years after moved from Belgium.

As you have mentioned on PM that I sounded arrogant lately, I apologize to everyone offended as it was honestly unintentional.

It was probably a poor attempt to add some weight to my opinion since I see a lot of cases where people either regurgitate info read elsewhere or offer unfounded opinions from not having the experience.

Anyway, I have no problem keeping my opinions to myself in the future if they offend people... I will sit back and enjoy the show...

Arse. I thought I'd deleted that post......

In the use of the new HH I have noticed that the changes of Set point or mixture sometimes do not come accepted. If in depth I change the set poit from 0.7 to 1.4, as an example, I have noticed that the machine makes the change with a delay of some second (on the display remains 0,7 also after that I confirm the change). I have the impression that is not therefore advisable to act fastly with the push-buttons, but to wait for some second. But sometimes I have had to repeat the procedure for having the change. The same thing with the mixture change. I attend clarifications from more expert persons.
Thanks

Mine will change pretty much right away. Hmmm. Better talk to Joe Radomski about something like that.
