Shopper looking to buy one of the Cressi-sub SL, what is the difference in performance between 24'' and 28''? also, does it come with the line or i need to buy it separate? and what kind of a gun pump? is it electrical?
LeisurePro S Gun is pneumatic and will come with the line. The 28" will be accurate for a distance of one foot more than the 24". A gun will be accurate three time the length of the shaft.
