Thread: Anyone use a dive watch?

If you're diving 15m regularly then yes, get a dive watch to time your surface intervals. Generally 1 minute is not going to be enough recovery time. I use a ratio 1:1 for shallow, easy drops then 2:1 for longer breath holds and 3:1 for long deep drops. Ratio is surface:bottom time. Eg 30 seconds down:30seconds up, 1:30 down:3:00 up, 2:00 down:6:00 up.
You will get a good starter model for that budget from any of the dive shops. If you hang around on trademe for long enough then you might get a good deal on a better brand like suunto or garmin.

You will be surprised when yiu start using a watch. I'll almost guarantee that your 15m float line marker is more like 9-11m and your current surface intervals will be either half or double what you actually need.
