Well got to try it out today with a back pack blower. It works quite well, especially damp sandy areas where it can dislodge partially imbedded brass. Also works in short to medium length grass, but not as well as sand dirt. Not surprisingly it doesn't work very well in wet dirt, and is not like blowing leaves around. Unfortunately to keep the any of the brass, it would need to be separated from sand/grass/small rocks. Do to time i just shoved it up and cast to side pile. Quite the winter, where the range is usually covered with several feet of snow and lucky to be in single digits.
