Solinst Model 103 [106172] Wireline Tag Line With  3/4" x 1 ft. (19 mm x 30 cm) Weight & Metric Increments, 100m. The Solinst Model 103 Wireline Tag Line uses a weight attached to a laser marked cable, and is principally designed for use during the installation of monitoring wells. The Tag Line also provides a simple method to measure the depth to the bottom of a well. It is also ideal as a multipurpose marked support cable. Markings are clearly and accurately laser etched every 1/4 foot or every 5 centimeters of the cable. The laser markings allow the cable to run smoothly over the Tape Guide. The Model 103 Wireline Tag Line uses durable polyethylene coated 1/16"" (1.6 mm) stranded stainless steel wireline with a minimum break strength of 270 lbs (122 kg). It comes in standard lengths of 100 ft. to 1000 ft. (30 m to 300 m). The cable is mounted on a sturdy free-standing reel with a carrying handle, weight holder and brake. The standard stainless steel tag weight is 1.5 lbs (0.68 kg) and measures 3/4" x 1 ft. (19 mm x 30 cm). A narrow tag weight, 1/2" x 1 ft. (13 mm x 30 cm), weighing 0.65 lbs (0.30 kg), is also an option. Tag weights have tapered ends to minimize hang-ups during deployment and return to surface, and can be clipped on and off the cable. This allows the use of the reel-mounted marked cable for other uses, such as bailer, or pump, and packer deployment.
