We have received and are using the Heavy Duty Black and White GeoVISION Camera System that I purchased prior to the holidays for the Upper Stillwater Dam Project in Utah. We are using the camera to investigate and monitor the grouting of cracks within the Dam below the ice packed reservoir level. The unit is performing superbly. It is submerged in 36-degree water 2 to 6 hours a day during grouting activities to monitor cracks within the dam below the impoundment level. We are using a 30-foot long section of 1 1/2 inch PVC as the camera housing (pipe string) with feed to an igloo where the monitor is housed. Ambient temperatures are 10-20 degrees F without wind chill.  The performance and durability of the unit to date is outstanding.

I appreciate you prompt attention and the quality and performance of the unit. It is greatly facilitating or grouting program. The Bureau of Reclamation dam inspectors were quite impressed with the high quality of the picture.

Dear sirs:

We received our new borehole camera last week and have been using it to map boreholes we drilled through our sulphur block. The picture quality was great, it was easy to use, and the service we received was excellent. Thanks so much.  Gord
