Current Cost?

Anyone know the current price of the Pelagian, and what the cost would be to have a 3 PPO2 monitor included as opposed to just 2?

Thanks

Hi there Marc,

The Pelagian DCCCR is USD 5800 and current lead time is 30 - 60 days.
Like many have suggested the main reason for not using a 3 cell display is that I belive it is a strong point having a second display that is completely isolated from the Pelagian display. If the Pelagian display would have 3 cell readouts you could of course connect only 2 cells and connect a Shearwater, VR3 or HS to the third cell and achine the same amount of redundancy. But you would then pay for a 3rd and unused 3rd cell read out.

I talked with Bruce from Shearwater. The Pursuit can be used with one or three cells, but the HUD currently needs three cells. He said that he might consider changning this so that the HUD can also operate with only one cell given enough interest.

If you are happy with the level of redundancy found on most rebreathers, i.e. two displays reading the same three cells and thus sharing signal and ground you could order the Pelagian with out any display and then ad a Pursuit and HUD reading the same 3 cells or any other similar solution.

My next project is taking the opposite approach: A single cell display to be added to the basic Pelagian. This will give the same resolution (three decimals) and fast update speed as the standard display and of course be hard wired all the way.

The reason for this is that the pelagians Instant Cell Validation needs fast update to make sense. Most dive computers only show two decimals and the update is not fast enough to validate cells on half a breath.

All the best,

Sorry for a bit of newbee question..

Is it possible to have both a HUD and a Shearwater Pursuit or VR3/HS-Explorer hooked up to a cell in the pelagian while keeping two cells reserved for the original controler. Doesn't one need four cells for a setup like this? Is there some type of cell splitter/amplifier or is the current of one cell strong enough to produce readings for two diffrent devices?

Cheers

The shearwater HUD should be fine running in parallel with the standard electronics, if for some reason the pelagion electronics didn't like hta I'd guess that you could hook all three inputs of the HUD to one cell - best check with Bruce first though

This is the standard intended use and this would also preserve electrical isolation between the Pelagian display and the added displays. Also the intended use of the Pursuit and Shearwater HUD is to share cell(s).
According to Bruce he will modify the HUD so it accepts running of one cell if you order it that way. Otherwise you could use the VR3 and Delta P HUD to run off one cell.
