Info Experience report: Scubapro Aladin Sport Matrix – a great computer, but…

I don't think you can do this.

The manual shows a 6m stop because the deco stop obligation's ceiling will be, depending on the dive profile, along the classical 12m, 9m, 6m, 3m range (this still based on Haldane's original 10ft increments, even though the dive computer is on a Bühlmann algorithm).

That said, for a 3m stop (which is going to be the most common, along with the 6m stop), you would be in the deco range starting 1.5m / 5ft below the stop (page 20 in the user manual), meaning you can do your stop at 4.5m if it's too uncomfortable to do the stop at 3m (and similarly 7.5m for the 6m stop).

Thank you. This helped a lot
