With the beginner, the body is lower in the water causing SwimFin to be more submerged, hence giving the swimmer more uplift and support and the arms are not restricted.
Less Support / Buoyancy
As confidence grows, there’s a more improved body position.SwimFin appears more out of the water, now giving a little less support.SwimFin does it automatically, working with the swimmer’s natural ability but also giving the immediate support if required.
No Support / Buoyancy
In a horizontal position, SwimFin is virtually out of the water giving very little or no support so even the better swimmers can wear it all the time.Just remember, if it’s out of the water it’s no longer a buoyancy aid but a fun toy for the kids.
