I have a Lake Systems Combo-C-Lector for sale. It reads pH, Temp, & Lure Color. It has a small crack in the probe cable that is sealed with silicon just as a precaution. It is in very good condition & works fine. Comes with a hard case and an extra pint of pH calibration solution. The directions are in rough shape (they got wet once). If anyone has a copy of the instructions I would appreciate it if you could E-mail or fax me a copy. As far as price I'll entertain any serious offer. Buyer to pay S&H and Insurance.
