Congratulations on the new site. It is much improved. I realize the work that must have gone into this endeavor and know that it is still a work in progress, but I do have a few suggestions…
I noticed that the nomenclature under the speargun descriptions is very vague. For example it will give a shaft or sling part number but no dimensions. Listing the dimensions and specific features of the shaft, sling or gun will help people narrow down and decide what gun to get or what replacement parts to order from their supplier. Giving the part number to my supplier has resulted in the wrong shaft being delivered on several occasions.
I think that just adding a few columns to the table under the gun that list's shaft size, notch or sharkfin etc., band dimensions, wishbone type, etc would make a big difference. Same thing under your replacement shaft's and sling section; there are a few pictures but absolutely no descriptive information such as which correspond to which gun, part #'s, size/dimensions or individual pictures, etc.
Keep up the good work; you are definitely going in the right direction. I see a new and improved JBL brand emerging and the more recent innovations, such as the “elite” series are definitely getting noticed!
