The new Lynx Air Flow sole design prevents dipping on the head on the downswing for exceptional swing consistency and accuracy.
Vane anemometers or heated head air meters may be used to measure air flow in ducts.
One houses the combustion chamber with a specially constructed air flow passage and burner head to eliminate combustion air turbulence and flame roar.
The wind speeds up significantly near the top of the hill and the air flow should be reasonably smooth and free from excessive turbulence.
If you do not have soffit vents, like me, only a minimal air flow will be felt.
