Solinst 103 Tag Line (laser marked) 300ft comes with tape guide Part# 106142

The 103 Tag Line is used to measure backfill layers and total well depth during monitoring well construction. It uses laser marked cable or tape, with a stainless steel tag weight on the end. A narrow tag is also available.

The weight can be clipped off, allowing the reel mounted, cable or tape to be used as a support (i.e. for bailer, pump and packer deployment).
