Found out this the hard way when I used a Mos as my backup timer, set my main Stinger to Gauge and the Mos to Free. The Stinger was cool, but the Mos started beeping at me and would display "Er".theskull once bubbled...
The only thing it won't do is go into Gauge mode (bottom timer with depth, but no NDL calculations). This should only be a concern for those who plan to do decompression diving.
So think about what type of diving you may wish to do in the future? If you have no plans to go tec then it should be fine. Personally I like the look of the stinger as I can wear it on weekends and even during the week, as it looks quite smart and functions very well as a day to day watch.
