Megalodon or Pelagian

rogeringebo · 3rd March 2008, 08:56

Hi Mike, Andy and the rest of you!
The cells are laying down (see picture). I have not had any problem with drops or moisture on the sensor faces. As the diluent is blown past the faces when the ADV is triggered you can actually dry off some of the condensation. As you can see the treads are taken off the cell so the gas can reach the face.
When it comes to WOB I can not feel any real difference as they both breath very well in my book.

Excellent post roger

The weight of the pelagian is a very strong positive, especially with airline weight restrictions going in one direction. As someone else said, proximity to manufacturer is really valuable thing, especially when you're based in asia.

oh and carl, someone did a great sales job on you matey.... the kiss is one of the few units that trims well.

I have also tried the Pelagian and I did not notice any difference in WOB compared to YBOD.

The trim was really good and the unit felt more like single tank than Rebreather... Really easy to swim with.

I would like to own one...

Pro and contra for the 2 rebreathers

One big con for the Pelagian is that it requires the owner to modify the unit to make it safe. 2 sensors just doesn't cut it. There are way too many dead divers to demonstrate this. Now, adding a 3rd sensor isn't that hard but expecting the diver to do it is just not good enough. I realise that the manufacturer thinks that 2 sensors is fine as we have been around and around on this before. It truly worried me that he didn't know sensors could fail high and low.

This is the thread in which it was discussed. http://www.rebreatherworld.com/pelag...agian-way.html

The rest of the points are great to read about but as an off the shelf product the pelagian is a non starter due to this deficiency IMO. Another thing to consider is. Which training agency will your C Card be from? Who will accept it? If I was shopping for a manual unit, I'd go the Classic KISS. Have fun making your choice.

I have never dived a Pelagian but when I was looking for an mCCR it was at the top of my list for quite a while. Then I saw one in the flesh and crossed it off. It looked and felt like it had been made on the cheap in a shed somewhere. It made sense when the guy on the stand told me that part of the design philosophy was to build a unit that could be maintained using commonly available parts in 3rd world countries.

I live in the UK and spend a fair amount of time in the USA so for me getting parts isn't a problem. What was important to me was the build quality of something on which my life would depend, the units resilience to flooding, WOB in any position, one handed operation, support from the manufacturer, ease of in field maintenance, lead time of the unit, stability of the manufacturer and the availability of a quality instructor.

I went with the COPIS Meg.

At the moment the choice is TDI, PSAI or IANTD.

Hi!
I never had any problems with the build quality of my Pelagian after about 300 hrs on the unit.
On the other hand my Meg had some major issues and the list of problems on my Classic KISS is too long to even get started.
The Inspo, Meg and Evo we have where I work have been back to the factory more then once so I do not think there is a lack of quality with the Pelagian.
Quite the opposite...

I started a course on the Pelagian today for one of our former students. Why did he pick the Pelagian? He spent a day diving each of the Vision, Meg and Pelagian. Whenn he had finished the Pelagian won hands down due to ease of breathing, comfort and transportability.
As Matt already said, try and dive both and then YOU can make a conscious decision on whats right for you.
