Looking for suggestions for digging frozen ground. I hunt farm fields mainly. We recently had a cold spell when a new record was set at below zero for 78 hours straight. Some of that was close to -30 degrees. There is no snow on the ground but it is rock hard. We do get above freezing often so I can go detecting. I am checking to see what people are using for picks. I see Apex makes several picks. Will the hickory handles hold up. Thanks.
