I drove my wife to work this morning. It was well before sunrise, and on the way home, I hunted a couple of hills. The first hour was spent in almost complete darkness, except for the luminous snow partially lit up from the 1/2 moon that was shining under an otherwise clear sky. It was quite cold, with the ambient temperature showing -18, however with the wind factor, it was more like -25. I ended up with some icicles on my mustache and beard directly below my nose.
The AT Pro is starting to convey it's subtle messages. I can tell a shallow coin from a deep one just by the tone. The depth readout is very accurate, as 2-4 centimeters is shallow, and based on the tone audio is almost always a coin. Our dimes give off that low iron grunt, and if you raise the coil another 5-6 inches and play with the signal, you start to get some belltone sounds. Our quarters, if lying at or near horizontal, give a nice belltone and give a numerical digital readout of about 74 to 78 with a stable audio signal. If they are not lying horizontal, you get a mixed belltone with an iron grunt. I tend to dig most of my signals anyways, as it costs my nothing but about 30 seconds of my time. The more junk I dig....the more I learn about the audio on this machine. And I should mention, that for snow hunting, I hunt in the standard mode. It just works better with our common coins.
Below is a find from this morning. It was buried about 4 inches, and after it warmed up in my pocket, I got it to work.
Nice hunt!!!!
