Who knows the JW Fisher Pulse 8x?

[Anonymous]

I just bought a used JW Fisher Pulse 8x - my first Pulse detector. Seems in real good shape though the bottom of the coil shows alot of wear and the rubber boot for the cable at the control box is pulling away (was caulked not so well). Still the cable electrical connection itself seems real tight, though maybe just not leakproof.
My problem is I cannot test it in the field being only 13 degrees F, while air testing is having horrible results!
Indoor testing in "low" required a wheat penny to be within 1 inch of the coil to get any signal (audio). "Medium" got maybe 2-3 inches and "High" got only 4 or so inches in depth. "Battery check" yields a needle deflection all the way over to 9.
I have no operators manual yet.
Is something wrong with this unit? I thought Pulse machines had killer depth?
HELP!

Mr. Bill,
Thanks for your help once again! I was thinking too simplistically as I had heard from more than one source that PI technology cut through minerals to go deeper, and that the 8x was the best pulse unit at ignoring minerals, so I made assumptions.
I will say it suffers no interference problems or chatter whatsoever in my house, but it isn't trying to discriminate either.
I did call JW Fisher and speak to technical assistance. They had me set the needle on 1-2 rather than zero, and then it appeared to work properly with better depth results.
However, the Fishers literature claim that this unit detects a penny at 9" is to be taken with a big grain of salt. He said that the needle will deflect slightly on a 9" penny, but I found no accompanying audio. So I guess if you want to walk around staring at the meter looking for slight deflections but no audio, this is your unit! I think I will be putting it on Ebay and looking for something for shallow water and land.
