The price is primarily driven by material composition, such as High-Density Polyethylene (HDPE), Nylon (Polyamide), or Polyester. Buyers should verify the denier or twine thickness (e.g., 210D/9 to 210D/120) and mesh size (stretched or half-mesh) to ensure it meets specific fishing requirements. Additionally, knot type (knotted vs. knotless) significantly impacts durability and price; knotless nets are often preferred for reducing fish injury and maintaining consistent mesh geometry under tension.
