The DR-3 is often referred to as ‘the short DR-4’.
The DR-3 is suitable for pipe ID range 65mm to 115mm (2.6″ to 4.5″).
The DR-3 has proven to be the tool of choice for mapping electricity cable conduits which combine a mid-range diameter with tight factory bends.
The compact design and choice of materials has kept the weight of the probe down to just 1.5kg/3lb, making handling and operations very efficient and simple.
