USGS Sounding Reel, B-56, Metric, Extended, w/0.320 Dia. Cable, 60m

The extended length option for sounding reels was primarily intended to extend the B-56 Sounding Reel to allow it to be used with Tacoma Bank Operated Cableway (BOC) and extend the Tacoma BOC range to 290 feet (90 M). This is accomplished by building the reel with a longer drum.  The basic USGS sounding reel design philosophy has always been a single layer of sounding cable on the drum rather than multiple layers which can crush the outer sounding cable strands thru the insulator surrounding the inner copper conductor causing a short.  Two extended length B-56 models are available.  The Model 104-055 has 220 feet (68m) of .10" sounding cable or 175 feet (53m) of 0.125" sounding cable.  The Model 104-057 has 290 feet (90m) of .10" sounding cable or 230 feet (70M) of 0.125" sounding cable  The extended B-56 sounding reels are designed for the same sounding weight or sediment sampler operating loads up to 220 lbs (100kg). The extended reel will fit on existing Type A and E cranes also.
