Periscope Pinpointer

I currently use the periscope pinpointer. I purchased it in 2000 when I owned the white's XLT. I wonder if anyone has bought or plans on buying the patent on it. It was made by Ott Technologies located in Akron Ohio. It is the most durable probe I have ever owned if used properly. I know it is bulky but I have long since gotten used to it and believe me it really works quite well. If someone could buy the patent and modify it into something more compact that would be great. There was a field test done and written in an issue of Lost Treasure Magazine. Just go to their site and look up the test or just simply google the term periscope pinpointer to find the report.
