No more iron sands! A revolutionary mechanical net releaser that does not use magnets. Ensures smooth and comfortable landing work on and off. No magnets are used, so it will not adhere to unpleasant iron sand when landing or shooting and will not affect any equipment that hates magnetic force. Unlike magnets, it is easy to notice dropping when you row, etc. There is a Velcro type that attaches to the frame of the landing net and a ring type that attaches to the grip ends, so you can choose the one you like. Each type has two spring strength varieties, so you can choose according to the size and weight of your net. Note: Please note that the net of the delicate frame may be damaged. Be sure to check the strength before using to remove the net to ensure it does not damage the frame. Please be careful of losing the net due to accidental dropping. Type: Ring, Velcro Spring Strength: 3kg(Gold), 4kg(Silver)
