Well not exactley I've hunted woods and blanked. But to answer you ? I use historicmapworks.com overlay is great! I usually pick places with water very close, start at woods shoreline and work my way out. Remember with wooded area that your target I'd is not accurate because getting coil flat and directly over target is difficult. Good luck, ohh I prefer larger coil first ( cover lots of ground) but I always pack 5 inch to cover tree shrubbs.
