Depth statement given as a real number in metres for a <waypoint>.
Normally, every <waypoint> must contain one <depth> statement. The only exception from this rule is the calculation of an ascent profile (see <calculateprofile>>) — because in this case the profile is to be calculated, i.e. time/depth values.
(see also <waypoint>)
<!-- a dive depth of 18,4 metres --> <depth>18.4</depth>
