Frozen Ground

Decided to take the F-75, with the small coil, to my relatives house knowing that the ground is still frozen. House built in the 40s with a couple of acres. My plans are to really give this place a good going over when the ground thaws but thought I'd see what kind of targets the machine would identify. Lots of classic (high 4H) tone targets of the sharp response type but ground was too hard. Decided to try along the edge of the long blacktop driveway and discovered that a couple of feet either side of the driveway was not frozen. Apparently, the black asphalt absorbs the sun rays and radiates the heat into the nearby ground. Thought I might pass this along to some of the other frozen North folks so maybe they can get out for a while. Right along the edge of the road can be a real productive area. As soon as I started working the edge of the asphalt, I picked up a Rosey dime. Had to go inside but I'm going to hit it again tomorrow.

It pains me to admit this but most of my time was spent using a detector that was unmanageable. Found no solid targets and whatever I did find seemed to move around! GB was 50 and the machine was generally quiet. DE, Sens 70, 4F and Disc. 5. Really had me baffled until I looked at the toggle switch on the FX-1. Yep, it was in the probe position. So if you have the FX-1 and your F-75 starts acting goofy, check the toggle switch.

I had a DX-1 on my DFX and more times than I can remember, I walked away from a hole with the switch in the probe position. After a while, I would check it when the machine ran silent. I hate to think of the missed targets.! Glad you were able to get out. Ron
 
Dontcha wish Sunray had put a little red LED in the left corner of that box that would light when the switch was in the "probe" position? I just added one to my F-75 and I can see having the handle/shaft block the switch from sight is going to lead to the situation you describe frequently.
 
Considering attaching a small floppy spring, using a hose clamp, to the F-75 handle just forward of where the front of the FX-1 probe sits when it's in the mounting clips. Either the spring or maybe attaching a small coin to the spring would bob back and forth in front of the probe constantly whether the F-75 is searching the ground or held above the ground. If you forget to switch back to coil, I'm thinking all that racket should get your attention.

Sunray needs to put a auto feature on the probes like my Fisher 6x. You lay the detector down and it turns the probe on, pickup to hunt and it switched to the main coil. I wonder if Fisher sitll owns the patent on this idea?
