It’s dangerous, since hyperventilating removes co2 from your blood, and raised co2 level is primary trigger for the urge to breathe reflex. It may feel better to hyperventilate and dive longer but you’re risking suddenly blacking out. I’m a free diver and this is one of the first things you are trained not to do, as well as never to dive alone, for safety reasons.

If your problem occurs because of accidental zooming with two fingers, then there’s a solution for you.

You can zoom map with just one finger (I use thumb) – do almost a double click but instead of releasing the second click, hold it pressed. Now as you hold it, just move thumb up and down to zoom in and out.

It’s a feature I discovered accidentally a few years ago, and in my experience pretty much no one knows about it, but once shown, everyone finds it extremely useful.
