Jay when printing TOPO 4.0 maps the file will normally be a bitmap. To print a good map, select the map area you want on screen and go to print+lock scale+ set the scale to the size corresponding of your county map. Most of those are 1:125,000 which will print out on 4 sheets in a map about 15.5 x 20 inches. With TOPO your not likely to get just one county only on the map. Depending on the size and shape of the county you will get parts of other counties too.

If you really want to digitize and use your old county maps so you can set waypoints, draw lines, and measure distances on the computer, you will need another mapping program. We use FAGAWI, which allows you to scan in any map in any scale and by setting three known GPS locations in a triangle the scale will be recorded in the program and from then on will put waypoints on the scanned map accurately.

This works great on old 19th century maps that have few man made landmarks, like in AZ, NM, and other wide open spaces. With TOPO 4.0 you can get the exact GPS location of any mountaintop or landmark that is on both the new and old maps and type it in FAGAWI and your scanned map will be nearly as accurate as TOPO.

I can see no point of using just a county map unless it is a USGS topo map. Most of the run of the mill maps printed by county officials are just line maps with place names streams, roads etc. In treasure hunting one must have true topographical maps. In most cases the signs and symbols found carved on trees or rocks in treasure areas contain topographical information. Don't get caught up in the Spanish treasure trap, most treasures are not Spanish and were buried using actual topographical maps of the period the loot was stashed. You must have the identical map used by the guy that buried the treasure to use as your pattern. Its pretty complicated and I doubt anyone could understand our methods of reading symbols and applying them to maps but it can be done. In fact, it must be done and done correctly if one expects to find the loot.
Hope this is of some help..
