INDEPENDENCE PARAGLIDING RESERVE, TANDEM SIZE!
Normally, this would be a reason to get very excited - used tandem PG reserves do not grow on trees! However, this one is about 22 years old I think - I am checking up on it. As such it, isn't a brilliant purchase, given the way manufacturers have decided to reduce their recommendations of reserve life. Being, old, this reserve was built to a much higher weight and (perhaps?) strength than many modern canopies.
Do you want to use it? It would save you a fortune over a new one, but it may not be as good at saving your life. I'm a dinosaur, so I'd use it, but you should make up your own mind.
The price is a guesstimate. make me an offer, but not too silly.
