The Shearwater can be set for 3,4 or 5 minute safety stops or you can set it for adaptive safety stops. They will change to a five minute safety stop if the dive exceeds 100' or if NDL reaches 5 minutes or less. At the safety stop you can indicate by sign language to your buddies that you have 2 more minutes remaining and when it clears give them the signal for all clear which is by sweeping your hand back and forth across your forearm.
 
Safety stops can be fun. We were on one last week in Cozumel and @northernone and I saw a Marlin in blue water while on our extended safety stop. That's a rare sight in Cozumel.
 
I believe @boulderjohn has a good story about why you should understand your dive computer. Something about an "experienced" student that thought their computer's AI sensor was analyzing NITROX for them.

"It's perfect 32% every time".
 
Shearwater has released a major firmware update for many models including the Perdix. This update changes many of the behaviors previously discussed in this thread and makes much of it moot or incorrect. The release notes with a description of these changes can be found here.
