I have always used the pole in the same way, as Gardiners promo videos teach you, add sections together and raise.
As for age of pole it’s as good condition today as when it left Gardiners workshops, not a mark on it, after all it’s done nothing compared with your every day pole. Carbon fibre does not age, it does not deteriorate, yes the outer lacquer coatings may deteriorate over time and allow carbon fibres to fail but this pole is still in good condition.
I didn’t know there was a Mk2 version? That’s very interesting because I think now this is the Mk.1 because when I had to replace section 5 when it snapped in the an exact same fashion, 8 inches from the top, the replacement I had to buy is certainly a lot stronger and far better manufactured as is the No.2 section that I had to replace after it frayed it’s self to death on both ends.
To me that says they knew these poles were weak and have upgraded them! Very interesting.
