Changing the gradient factor will show you the need of a compulsory stop, no more a safety stop. Isn't it?
As said, for a safety stop, just count 3 min at 20ft.

Agree with Wayne. I wanted a wrist computer that had all the options for rec and tech including up to trimix but didn't have air integration, or silly stuff like a heart monitor. The Petrel is on my wishlist to compliment my Predator. Unless all these guys buying Petrels decide to sell their Predators. Then I have no problem getting another one of them if the price is right. I also like the amount of control I have and that Shearwater treats me like an adult when it comes to planning and executing dives.
"It's way more computer than is needed for that level."
As for this statement so are most of the computers out there. For recreational dives a computer is really not needed at all. A simple bottom timer and tables will work. Yet we have vacation divers sporting Luna's, Sol's, ProPlus 2's, Cobalts, D9's, D6's, D4's, Icon's, etc.. All of these are way more than needed. To me these are more of a waste of money for purely recreational divers.
You guys got me thinking ... i have the preditor. i thought it had the 3 min stop in it. also a setting for the min depth for stops in general. i have mine set at 20 ft. now i have to go home and look. try the planning mode, it is very easy adn see what it says.
wow a simple question turns into a flame thread, really? The reason I asked about the Sunnto/Shearwater comparison is that most of the divers I dive with use Sunnto so it makes sense to run something similar, I also like that it's quite conservative as I have used one for years. I have done a fair bit of research so please don't imply that I bought this computer for any of the reasons you stated above, my plan is to grow into the functions of this computer as I progress. I'm also quite confident I could count down 3 minutes at 20ft I was just asking if it was built in as I did not see it in the manual I have read multiple times.
After doing my first 2 dives 30/80 seems pretty close to what i'm looking for, for the people who offered advice thank you very much!
The only problem I see in diving is the divers who think they are better than everyone else and like to point it out, most people learn from reading/asking questions(even dumb ones)and experience. Putting all the reading I have done with a few dives today and seeing how things work made it all come together(at least where I'm at now) Yes I may have burdened a few tech divers with dumb questions along the way but no one is obligated to reply. The LDS I bought the Petrel from were not even dealers until I asked them to get it so it's not like I saw the pretty lights and bought it. This has been a 3 month process for me and taking recommendations from people who dive recreational and tech, quality/workmanship and customer service were key factors in the Petrel vs another computer, some tech divers recommended it as a great computer to advance my diving with but I guess I should have checked with those who "have been around a while" first.
