So my little Powershot n tragically died because I rode my luck a few times too many with off-shore winds. The lesson to learn is to stick as much as possible to nice clean on-shore winds.
Why? Because off-shore wind usually is traveling over buildings, trees, sand-dunes etc. which all affect the flow and make for more swirly and inconsistent flow. Whereas, on-shore wind flow is generally much cleaner and less prone to looping or dragging the kite sideways and then into the ground.
if you can get up high enough, sometimes the off-shore wind is fine, but the danger zone, and risk, is always closer to the ground when you are reeling out or in.
