You can also mount one of these to the rod. Fuji plate Reel seat. These mount on the rod flush to the deckhand grip. They are secured via top, bottom and middle of the seat with thread or cord wrapped around the rod ( Corktape or Shrinktube) and seat. You then epoxy over the threads/cord to seal it and secure it to the deckhand grip . Works really well. If you decide to sell your rod, you can remove it.
Tiburon best bet.
I have a 800m graphiter with tuna cord handle.
Puts it at the right location for casting and fish fighting.
Thicker handle will require longer screws so be sure to check fit before you buy it.
