I did my best to get Jach to buils the Odesey so I could use any size 
takn on it. We then compromised on 40's and the way they were set up 
the unit was 41/2 feet tall. Then he decide to put the four weenie 
bottles on it and for me he added to quick disconnects that allow me to 
use any tank(s) I wish to use. At this point I see the weenie bottles 
as deco and my dive gas in the bigger cylinders.

Also on Cis the MK5 as I told you ius not what you have seen in the 
field with Stone it is small and compact and weighs in at 55 pounds. It 
can be used with any type backplate you choose complete with stage d 
rings etc. It has the ability to switch two other stage tanks of any 
size onto the unit and a simple switch boz. The stages can be breathed 
thro the closed circuit or open circuit. It is reaaly a sharp unit. As 
you know I too had reservations about the 4 but these units are night 
and day different. Much of the changes have been due to field input 
exspecially from Rich open warer researc, and Kevin Gurr internal 
shipwreck (UK) and deep openwater diving. Kevin is a sharp and bull 
headed engineer who has been able to influence the unit quite a bit.

I hope to have a modified 4 soon to work with until the 5,s are 
produced in August. I do not know how many of the mods will be in it 
but I will let you take a peak. The 5 is also real streamlined and can 
be set up is any clean configuration that is applicable for a RB.
