Any news?

Are you going to sell these in the supermarkets to get the volumes up with such tight margins?

Will points vouchers gained on the unit purchase be exchangable for consumables? Can't wait for low season BOGOF's on EAD's and Cells!

We collaborate to get better functionality and efficiency. Nothing sinister. On the advise costing half the unit: we look to instructors to give advice. They charge a fee for training, and need to provide that training. It will not have nice long customer chats on the phone: it is a product described with a datasheet, and the only advice is a list of trainers. This training element is the bottleneck for the shipments, so is getting a lot of attention.

A few people have emailed me on the combined ADV and BOV, with auto loop shut off. We did think long and hard about this, and also sponsored another company who were trying to do this for quite a while (they packed it, so we did our own). Here is the philosophy behind it:

If a diver needs 10/50 when below 60msw, then he should not plug 10/50 into his ADV on the surface. Doing this is a factor in more than one fatal accident.

Safe diving demands that the ADV gas be breathable at the depth the diver is, so he can perform a flush safely, and preferably with enough oxygen that if the O2 injection fails, he can ascend in SCR mode. This means that for dives where hypoxic gases are need, then the diver should use a gas switching manifold, or gas connectors.

Many divers are going well beyond their experience with rebreathers deep, and the lack of gas switching is one of the signs of that. Putting a hypoxic gas into an ADV is a hazardous practice: ADVs also free-flow, and there are various points where the diver reduces the loop PPO2. For example, on water entry most divers trigger the ADV, when stepping off the boat they often go off the loop to say something and breathe a lung full of air into the loop when they come back on reducing the PPO2. All it takes is the O2 to fail or be off, and the diver is going to be out quickly if the ADV dilutes the PPO2 even further and the rebreather fails to deliver O2 at the same time (it is not unknown for divers to run out of O2 ).

By putting the ADV and bail out as one in front of the diver's mouth, the intent is to make it obvious how hazardous using a gas in the ADV that is not breathable actually is.

On the original Inspo, there was no ADV and trimix divers had two buttons for gas addition. This was nice and safe, for divers at that level. The wider user base needs an ADV, but when ADVs replace those buttons, the buttons have to migrate to a gas switching block. We don't see any extra hazard from putting the ADV on the diver's mouthpiece: it might avoid divers using hypoxic gases without a switch block.

Hi Alex.Did I get it wrong or where you not going to post some pictures this weekend - as in no later than yesterday. I've been online more or less the whole weekend waiting and waiting.

Where are the buttons for manual O2 and diluent placed?

Cheers
Soren

I added the scrubber pic to the original post. I will post some further pics tonight. Sorry, I did not know you were on the edge of your seat waiting for these.

The manual O2: for the eCCR there is no button, for the mCCR the button is on a hose (2 hoses from right tank). The manual dil button is the ADV which will be on the mouthpiece (on the shoulder in the picture I posted).

On prices, the mCCR figure you quoted is correct, but the monitor is going to be that in Euro at least at the beginning.
Cheers,
Alex

DEMA 2008 is the launch.

Factory service is replacement of 4 O2 cells, calibrate the CO2 sensor, and will cost similar to other company's head services. Sending the monitor assembly is a nice small shipment, and we will set up local servicing once the main release is out of the way.

silent running

Hi Alex, how often does the diver hear the voice alarms? Does the voice tell you if your PO2 spikes, say on descent? Or when your NDL is approaching?

I'm concerned that the voice alarms will spook wildlife as I have seen buzzers on Inspos do. I certainly wouldn't mind hearing it if it was something really life threatening like a hypoxia alarm, but the thought of spending lots of time and money putting myself in a situation where I can get close to skittish wildlife only to drive them away with a alarm voice telling me that my PO2 is .1 over SP, is unacceptable. Thanks, -Andy

Pawel Szopinski

yup!

The voice alarms can be set up for several different levels via the USB port.



The Stealth level is the most useful, in that displays only come on when there is an issue, and voice comes on if something is outside the control range. It does not tell you that PP02 is .1 over SP (it warns if it has lost control in which case it will report 0.2 PPO2 error, but takes into account the effect of increasing depth, so a spike on descent has to be over 2.1 to give an alarm. It uses the tank contents, so flushes do not cause an alarm unless it results in the PPO2 being outside the safe range).

Alarm matrices are something we are still tweaking though. What a commercial diver wants is very different from what a sports diver wants.
