I own a mares cyrano 700 and am leaving on a trip to grenada at six in the morning. I lost my manual, how many times do i pump this to reload required pressure when i land????
for the guns above or just 90cm you could achieve 30atm with 550 pumps...

please confirm this because I found that data on a spearfishing mag. and its general for all pneu.
