The 103 Tag Line is used to measure the depth to the top of backfill sand or bentonite layers during the completion of a well and to measure the depth to the bottom of a well.

The Tag Line uses polyethylene coated, permanently marked, stainless steel wireline and a 3/4" stainless steel weight, mounted on a Solinst reel. Other sizes and weights are available. Cable markings are accurately laser etched every 1/4 ft or 5 cm. Ideal for use when installing Solinst 403 CMT Multilevel Systems or 401 Waterloo Multilevel Systems.

The weights can be clipped on and off the cable. This allows for the reel mounted, marked cable to be used as a support line (i.e. for bailer, pump and packer deployment).
