Features: Made of lightweight and high-strength reinforced aluminum, the wavy arm improves ease of rod placement. Features Stability: Features an "inverted taper shape" where the legs are thinner at the top and thicker at the bottom, providing a low center of gravity and stability. Leg Length Adjustment: Easily adjust leg length with a one-touch lever. Movable Arm: The angle of the arm where the rod is placed can be changed, allowing you to adjust the rod's angle according to fishing conditions. Maintainability: Designed so that sandy legs are on the outside when stored, preventing sand from entering the pipes. Thank you for looking.
