Pond float with hollow bearing antenna and spiral wire loop. A groove has been made on the body of the float which houses the wire to avoid any damage and also favors the use of larger wire diameters. The clip-on wire passing ring is of the closed type to avoid damage to the wire. Very stable thanks to the fiberglass stem. Available in weights of 0.10, 0.20, 0.30, 0.50, 0.75 and 1g.
