Difference in Props?

Carlos - I recently purchased two Gyre xf 150's off the market place. They are both brand new in the box and have receipts with date of purchase 4-5-16. I cannot locate a manufacture or packaging date. My question is how can I tell if I have the rugged props or the standard props? When I check the coralvue website and look at pictures of the rugged props the pictures and the descriptions do not match up. For example, the description for the product says "Four larger blades compared to the 8 small blades on the old propeller" but if you look at the picture for the rugged props for the xf150 it does not show 4 blades it shows 12 blades. Its very confusing how do I ID which props I have?
