debrief

Visibility was shit and current strong and valve on tank was leaking so not all skills were done.
30 m -> 19 kicks/16 secs w/current
Natural navigation was way off, but we did fine this afternoon on previous pleasure dive. Feel confident w/compass, but would like to do the square sometime.
