For Sale Shearwater Petrel secondary for ISC Meg15 & Pathfinder

[Geo7]

Hi all, some handsets and HUDs came with my new to me Pathfinder, but I am having it converted to Shearwater, so this is up for sale:

It's the Shearwater CANBUS secondary that goes with the ISC Meg15 or Pathfinder. Is this a Petrel 2? They did not have air integration at the time.

Condition seems great, and I was assured it is fine (100 dives), but I can't test it. If there are problems, I promise to take it back.

$ 600 shipped to CONUS, or best offer (PayPal Friends only).

So is this one runs on DiveCAN (SW) or the IS-CAN bus (trying to see if I can hack it onto a DiveCAN system like JJ or rEvo — I’m assuming DiveCAN and ISCAN are not compatible interfaces)?

(Maybe @211ratsbud or @mr_v have some insight on this)

It's Canbus, but ISCAN as you pointed out. I am not aware of ISCAN being fully compatible with Shearwaters DiveCan. Except of course they were developed together and this Shearwater handset is made for the Meg15 and Pathfinder.

I think ratsbud does know A LOT more about this than me....

Yeah they’ve put me on track for that „hack“ I got in mind (modding mCCRs with CAN) — let’s see what works

@Mobulai,

Meg 15 has two networks. The secondary network supports only monitoring and is compatible with DiveCan in that regard:

Therefore, the computer in this case is only a monitor. I highly doubt that Shearwater creates individual software packages for each rebreather. More likely than not, you can probably hack the monitor by unlocking additional, non-ISC specific features, perhaps even the controller option. But I don't know how to do that yet.

More than I can bargin for anyway — for now I plan to replicate a diy solo board implementation of a DiveCAN head (the monitor side) — essentially trying to pack a revo in a sidewinder, so DiveCAN compatibility is the 1st hurdle. „Hacking“ (maybe the right firmware just needs the correct HW ver no) the SW itself to unlock is something I haven’t seriously entertained and might be out of my depth.

I was considering finding a DiveCAN controller (maybe from a JJ) to run with it for that project (I found a badshape cheap rEVO nerd1 with an occasionally whitening-out screen to mess around with but I’m not so sure it would work, and definitely don’t wanna take it into the water) but maybe a monitor is a good 1st step since I’m starting out with an mCCR — solenoid selection and eccr functions come later

I should stop hijacking @Geo7 s thread and start another one maybe; but seems likely that this IS petrel can serve my purpose— lemme think about it and and will reach out on DM soon (I „just“ bought an AK P3 from ratsbud so it might be superfluous)
