How to track kick cycles
the distance when both of your legs complete one fin stroke. To track kick cycles choose one leg and count each time that leg returns to the same postion.
F.e. 40 kick cycles to swin 30m = 0.75m with esch kick cycle
Effectet by gear, fins current etc.
How to measure with elapsed time?
Measuring the time it takes to swim a known distamce.
F.e it takes 30seconds to swim 30m
Disadvantage: you can’t use it when xou stop or pause
Possible in additional to kick cycles
How to measure distance with cylinder pressure?
A specific distance per bar is only accurate at a relatively constant depth and breathing rate.
Good for measure distance in a relative send ober changing depths though when following a course you plan to return on.
Natural navigation
water motion: direction of waves, currents and tides
Sun direction and angle
Offshore Objects and formation
Depth finder from a boat
What to remember about current, when the tide changes?
A current can help you for navigation but it is possible for a current to change during the dive especially when the tides changes
How are the samd ripples generally placed?
sand ripples generally lie parallel to shore
