No AUDIBLE alarms on Shearwater computers. The flashing warnings are pretty damn obvious, though.
Like the big red letters that say Deco Stop when one stays just a fraction to long, too deep? In 146 dives, my Peregrine has given me that warning once. Fortunately, once I hit 40', it went back to a 5 min safety stop. I did not panic when it 1st showed me that though, as I pack a 30cu pony and thought to myself, OK, I should have enough air with me to cover that.
My Ratio DC, iX3M Tech+, allows me to customize the alarms and set some off while keeping others on, vibrate or audio or a combination of on/off for some scenarios not others.
The good news about those is they don't 'lock up' like some dive computers as if it's having a "scweem and scweem and scweem until it is sick" hissy fit.
I am sure the Zoop Novo in my console was not happy.
Know the tool that you are using.
DC lock up on me? NOT a chance. Give me any RGBM computers and I can use it without any issue over multi dives/days.
I have to travel to dive, do not dive in our local water, and I could not remember if I ever saw even one foreign diver using a Shearwater! There are so many alternatives at much lower cost. Just to remember: no DC have ever declared that DCS is thing of the past.
I assume you did not read the posts that explained things correctly before you posted this. Here is a quick summary for those who also skipped the informative posts.
1. Required limits are for instructional dives only.
2. PADI and SSI have instructional limits down to 40m for the appropriate dive classes
3. No agency has any authority to limit your depths when you are diving outside of instruction.
4. Local dive operations and governments have the authority to set diving limits.
5. The supposed limits of PADI and and SSI (and all others) are recommendations to guide divers as they gain experience. PADI and SSI recommendations extend to 40m.
6. Nearly all agencies limit recreational dive depths to 40m. After that, mandatory decompression stops are involved with most algorithms.
