Water definitely improves the conductivity of the soil to an extent...If the ground is overly saturated (water seeps out and rises above your shoes), then it can cause false signals to be produced in your detector...right now, in most of the frozen USA, the ground is still frozen below about 4 inches...As long as you can dig, you can hunt...I went out last week, and the ground was still hard as a rock below 3 inches...It was tough going, and I finally gave up after digging my 8th hole...I did find a nickel, and 5 pennies (3 copper/2 zinc). So it depends on how hard your soil is...In the meantime, I have gone to the malls and searched the snowbanks...The plows do us a favor and drag all that loose change into nice neat piles for us...search the snow banks with your detector, then dig with a metal trowel, or entrenching tool...
