Hey all hope everyone is well. I am just curious to learn how easy is it to set up a sentinal for diving, and also how complicated is it to use?
 
Don`t own a Sentinel and have never dive one, but think you have to do the pre dive check`s like on all rebreathers (more or less depends on the unit) and then dive, like on all the other rebreathers...........

Not the most useful post since the OP was in effect asking about the "(more or less depends on the unit)" by asking how the sentinel compares.
 
I don't find the Sentinel any more difficult to set up, prep and do pre-dive procedures on than any other CCR Unit. IMHO, those who complain about the tedious nature of the Sentinel, are more than likely to skip the procedures that they should be doing anyway on their other non-Sentinel units. In other words, the Sentinel will not allow you to take short cuts. Some people don't like that fact, and move on to other units that allow them to bypass important safety protocols that should be followed for virtually all CCR units. I see the required pre-dive steps of the Sentinel as a positive thing.

+ 1 on that for set up ,
As for use and diving ? It all comes down to the training and commitment to practice as any unit ,

As many I would imagine did , I felt in my first dive on mine " holy shit ,what have I taken on " but after training and many hours of practice you realise how much choice the unit gives to help get you out of a situation , the reason why it was classified as LSS ,

Now I love diving mine and it has never missed a beat and I've got the new wireless hp upgrade which works perfect :)
 
Is this a VR upgrade? I mean, I just got my head back from them a few weeks ago, had the new O2 module, OLED primary upgrade, new HUDs, the works. They didn't say anything about replacing the optical HP senders. Where are the receivers located?

The new HP transmitters directly replace the optocon sensors.
They're supplied by VR with miflex HP hoses, a long one for the Dil side, so that you can place the transmitter on the O2 side of the box.
I assume the wireless receiver is located where the FO cables used to connect to the head.

Yeh it's using the oceanic senders and receiver upgrade and software to the head ,, gets rid of the fibre optics that people seem to have trouble not breaking :) ,,, tidy too ,and yes VR upgrade just been released .

I've even been able to pair up my vrx so cylinder contents read on Back up too :)

Exactly right ,,, I've put quite a few hours in with it now and been spot on reliable , well worth the upgrade .
 
Yeh they need just the head , as for cost I'm not to sure what they are putting it out for at the mo but I think they have been doing an offer for existing owners for the first while ? ,,best to contact Tim at vr
 
OK, I'm in...

As an ex Sentinel user of the 'old school', i.e. bog standard, hard wired, Poseiden BOV'd I found the unit OK to prep. The drills were appropriate, orderly and well thought. In fact, I'd go so far as to say that the obigatory prep of a Sentinel has stood me in good stead for subsequent units like the JJ CCR which I am currently diving. There's much about the Sentinel which didn't suit my style of diving but the pre dive stuff was just fine.

HTH, Tim

The Sentinel is (in my opinion) a great bit of kit, however it gets a hell of a lot of negative comments on the forums...

Yes comments of people who propably never dives the unit. I'm quite new to Sentinel, but the rig is a pleasure to dive. Easy to set up and IMHO the safetiest unit currently on the market. Negativ is just the quite heavy weight especially on airway travelling. And due to this huge electronic kit, failure will occur like in a car full of electronics. This is the price for maximum safety I guess...
Cheers,
