New from ISC

technicall CAN-Bus
controlled area network-bus

used in cars to standardize the OBDII system and also in most industrial machinery. I think Bosch came out with it in the 80's sometime. Most people learn to hate it because the automotive industry has tied so many things into each other than the car won't start because the radio is unplugged, and think that's because of the CANBus, but that's a software issue not hardware.

What was said above is why I have avoided the meg during my hunt, analog is too dated and not reliable enough. The divecan is far more reliable than analog, but also allows the head to be upgraded just by plugging in new modules. They decide to add a temp stick or CO monitor and it just plugs into the bus and with a quick firmware update to the controller it will read it. Somehow a new O2 sensor comes out that is more reliable than the others and it outputs a different mV rating or has a different connector, you can replace that module separately without having to solder anything or get a new controller because it has 19 different wires coming into it. The advantage of not having the interference involved with low voltage analog signals is worth the upgrade alone.

The SW is hard wired (plugs in) and works as your deco computer but is not acting as your controller. So you have your SW technology.
The ISC controller will have deco software in it. The new one also has a compass, no longer requires lithium batteries (it's rechargable), is super easy to read for those of us who require readers.

I hope that ISC and SW will work out their differences to have the NERD available. I don't see the ISC controller going away.

I was not aware the ISC head could not be configured with a hardwired SW controller. If that's the case, I have no need of an ISC unit.

And unlike the Pathfinder, the micro revos are just fine at any depth/runtime - same scrubber capacity as the full size unit.

That is your choice of course! Since I dive both, I will tell you that MY personal choice for WOB is the Pathfinder (or a Meg) any day! The rEvo is possibly the best unit out there except that the negative static load of the counterlungs is not compatible for me in high work load environments. That is too bad of course because it is the best designed unit currently available (IMO of course).

I want to qualify the above by saying that a lot of people do not notice it. Breathing 0.8 Joules vs. 2.0 Joules makes very little difference in most diving operations. It's another example why there is not one single BEST unit out there and there is not one unit that suits all divers or dives.

Yeah, I don't require your acknowledgement of my right to choice and I didn't claim the revo was "best" or even "better" than a Meg (a Pathfinder...it's certainly more capable, but better is relative). If the WOB is conclusive for you, cool beans.

I'm mainly just surprised that ISC has failed to realize that however good a CCR they may make, they're not nearly as good as SW at making controllers.

What do you have against the Apecs? It's a good controller. The Vision is a good controller. The Shearwater is a good controller that came along after the vision and the Apecs. The Dream is a good controller. I don't know of any are better controllers.

 

[tbone1004]

The issue is they went through all the trouble of implementing the DiveCan, but then instead of using the controller it was designed for, went off and made their own which isn't nearly as fully featured as the Petrel. Try to wrap your head around the justification of "the company that designed the electronics for our head makes a damn good controller that the industry is in love with, so let's go and say **** that, and design our own that doesn't actually have any advantage over it and actually has less features. Yeah, that's a good idea, lets call it Apecs 4"

That's what happened, and it is utterly idiotic because the Petrel can do everything that Apecs controller can and more and probably for cheaper....

I think there is a bit of confusion here, especially from Wookie. The Dream is not a controller. The digital control for Meg and Pathfinder is ISCan, not the same CANBus used by rEvo. Each manufacturer has his own system, which is why a Petrel controller from a rEvo will not work on a Meg or JJ or any other. Standardization would be nice, but is probably a pipe dream.

And do I actually understand that Frank is going to cross over to the dark side after being so anti rebreather?


iPhone. iTypo. iApologize.

Anti rebreather? I'm only anti rebreather for me. Mel once told me I could have a rebreather if I: Hung up my wetsuit after every dive out of the rinse bin; took my first stage off to get a fill; and analyzed my cylinder and logged it in the nitrox log every day for a week.

Didn't even make it to the third day. She used this as an example of how I am not a careful diver.

I'm getting certified, I'm not buying a rebreather.

Did not mean to offend. Sorry you may have took it that way
