On www.kayakfishing.com (maybe yakfishing.com) I read that the transducer can he mounted using the scupper holes in your XT. Basically, one mounts the transducer to a block of rubber or whatever, then run a long bolt through the block, up the scupper hole, adding a big washer and topping it off with a wing nut. I didn't like it extending below the hull and hanging up on kelp. I went with the glued-inside-the-hull approach on my Scrambler and it works great but it is not portable.
