This unit offers many unique features. It can be purchased in three variations and two different heights for maximum flexibility. The height of this unit allows for the rod tips to be right next to the boat (in the water) while musky fishing. Keeps the rod handle waist height when laid flat out to the side trolling divers, fish disks or flat lining. Will keep the butt of the rod closer (out of the way) to your gunwale if pointing the rod tips toward the sky while using with planer boards. The oval base provides 45 degrees of side to side rotation All aluminum heavy duty construction.
