With a diameter of only 6.4mm / ¼”, it is particularly suitable for tracing blockages in fiber-optic microducting or for tracing other small non-conductive pipes. Locatable to 6.5' (2m) and measuring 0.25 x 3.5" (6.4 x 88mm). Supplied as a kit that includes sonde, flexible adaptor, 2 batteries and case.
