MEDIDOR DE DISTANCIAS A HILO PERDIDO WALKTAX DE CINTURA
Se trata de un medidor a hilo perdido donde un contador registra la longitud del hilo que sale del aparato a medida que uno se aleja del punto donde ha atado el inicio del hilo. Una vez terminada la medida se corta el hilo y se deja ya que es rapidamente biodegradado. Se puede contar cualquier distancia de 0 a 2.500 m .
