Just thought I would relate a happening on my past hunt.
In water about 30 inches deep I got a hit. I set my machine on the bank, control box lower than the coil and started moving some cobble. I grabbed the detector to do an iron check before committing to the dig. WOW! I'm glad I made that decision!
I had carefully searched in the river and watched the depth but forgot about the adjustment holes in the upper shaft. The shaft filled with water (apparently) and when I laid it down the water rolled back and was draining down thru the iron test trigger. Can't be good!
I am wondering if drilling a hole in the bottom carbon fiber shaft is a good idea?
I still have my old White's Goldmaster V-Sat. It's the same one I used when we hunted together at Crow Creek. I have two coils for it, the original coil it came with and the very small one that is used for tight places and bedrock. This is the coil that White's first put out when we lived in Alaska, small and black with no markings on it. Steve Houston introduced it when he came to Alaska on his promotional trips.
I don't use the original one because I find it impossible to ground balance with that coil, so I am limited to just using the small one. That's ok by me since most of my limited and sporadic nugget hunting is in bedrock areas.
The problem I am having is that I constantly get false signals and lots of other noise whenever the coil comes in contact with anything. If I bump rocks or brush, or if I even brush it up against wet grass it will false signal. this makes it impossible to "scrub" the ground as you advise people.
I am wondering if this problem might be in the settings on my control box, perhaps I am choosing the wrong settings? I have tried just about everything I can think of, but it does this all the time and is very annoying. Is there anything that you can think of that I may be doing wrong?
After reading a quote from Steve that older VLF Detectors will perform much the same as newer ones (just without some bells and whistles), I jumped and got a Goldmaster 4B for $250.
I know the adjustable frequency control is there for the detector to play nice with other White's Detectors in the area. Has anybody ever (to y'alls knowledge) ever modded one for a lower frequency range so that it would (conceivably) go deeper?
One of the popular mods for a Minelab SD2000 was to add extra frequencies so it would perform better on smaller nuggets. I would be interested in going the opposite way on my Goldmaster.
Any information is greatly appreciated.
Thanks - Mike
