Hang on a moment - this is just not true.

I have had small amout of water ingress into prism secondary and it manifested itself in a very nasty manner (slowly increasing ppo2 display) if I had been running manually........

If you were scrolling between sensors you would have seen the needle sticking and therefore know you have some sort of enduction.

I have used the analog secondary (old style prism) on my MK15.5 for a while until it crapped out (water ingress) then I switched to a MK15 analog secondary...after going through 3, yes 3 displays in a year I finally swapped to a digital MK16 one and BOY am I happy now!

Not sure how you did that, diffrent wiring and diffrent mlv out put?

Quote:

The ONLY advantage of an analog over a digital is it uses no batterys

Big deal! Its no big deal to make sure the battery is good.

I used to think that too untill speaking with Peter.

Quote:

The disadvantage of the anaolog secondarys are they are hard to read, they fail if you drop them, and they can STICK!!!

I totaly agree, but feel the pros out way the cons

Quote:

I would take a digital over an analog any day - its just more reliable...in my experience.

I am knew with very little experience, and even less knoweldge(just look at my spelling

) the most disheartning thing about CCR diving is that so many very intelegent and experienced divers have such diffrent facts and information. So what I have deceided to do is still question but basicly listen to only one person otherwise you will lose your mind

I bought the PRISM because of its electronic and scrubber design, is it perfect NO, but I am comfortable with its design and Peters advice.

Quote:

Chris - one option could be to get hold of a MK16 digital secondary and join it to your Prism secondary cable in a DIY junction box

With so much diffrent advice I would call Peter direct and get his answer and then make a discesion.

Or

You could get Colin Wilcox to sell you one of his new digital MK15.5 secodarys which IIRC uses the same lumberg cable as your PRISM. He may be able to help ensure the pins match.

Does he have a web site or an email? Could you pm me if it is not public info?
