What must be able to be done? I've found nothing to say that an integrated shearwater can be used as a controller on the meg; only stuff I've found refers to secondary handset replacement, to monitor ppo2 and track deco.
Technically a Shearwater could act as a Meg controller but Shearwater will not do it due to a contractual agreement and by extension it is my understanding that N@90 won't do anything that is prohibited under the same agreement.
I had a Shearwater on my Meg acting as a PPo2 display and doing online deco. From memory the cost was under $2k:
1 x Shearwater fully unlocked
1 x Shearwater Fischer cable
1 x sealing gland
Just used the secondary port on the Meg head and piggy backed onto the cells. Worked perfectly.
It's a little under £2k to upgrade a 2.06 head to the current 2.7 with a Shearwater. The primary handset is left alone and continues to control the solenoid. The electronics are replaced in the head so the hud runs from the primary and the Shearwater replaces the secondary.
I had a narked at 90 adaptor to connect a Shearwater through a Fischer cable before I upgraded the head - it worked very well but meant I had an extra handset to get in the way.
Dennis did my upgrade.
When I said to Dennis about doing this he said dont bother, just stick your computer on 1.2 ppo2...He said the deco wouldnt be to far out if I remember correctly
it's not necessary, but it is a really nice upgrade to use...
It really depends on what you want to get from the upgrade. I struggled to read the meg handsets - especially when deep & dark - I don't have that problem with the shearwater display. Of course, a nice oled upgrade to the handsets would have done the same thing but I haven't heard that it works reliably in cold water yet.
Most of all I just like having all the info in one place. I also carry a standalone Shearwater set on a slightly different gf that gives an identical profile to the integrated one - within a minute on a 2.5 hour dive.
I would also run out of arm space for two shearwaters and the primary handset - that's now clipped off to the lung as I only use it to change the set point.
Shearwater or scooter? I'd go for the shearwater as you'll get to use that on every dive
I want to do it because I struggle to see the handsets that come with the meg, checking ppo2 on them isn't effortless in the way it would be with a wired in OLED.
