Bullseye Quickload Review

I must say that everything you see and read about this product on this web site is accurate. I am extremely happy I ordered them and would order them again.
  I purchased a 4 pack for my Lund 1625 Fury XL Sport. I had an issue of not having enough clearance between the top of the trailer frame and the bottom of the boat to fit the 1 1/2" x 2" tubing for the rear guides. This issue is the same for Lund 1650 Rebel owners.
  Do they work? Yes they do. The ramp at the lake I normally go slopes towards the Starboard side. As you can imagine, it was difficult for this old disabled vet to get my boat centered. More difficult if there is a cross wind. This is no longer a problem after installing BullsEye Quick Load. When installing the load guides, I left 1/8" clearance between the boat and the guides. Thus making the boat centered every time with ease, even on windy days. My boat is loaded correctly every time the first time. No more backing up and reattempting to load my boat.
  These guides has made loading my a simple task.

First use today, couldn't have gone better!  My son doesn't like to drive the boat onto the trailer and he was thrilled at how easy it was. Lined up perfectly on the Drotto, too. 

Feel free to use me as a reference. 

Thanks again,
