user created custom maps for older versions of Garmin handheld GPS such as the GPSMAP 76 series
Cons
time consuming to use
poor quality of maps unless a great deal of manual effort is invested
Summary
anyone wanting to create custom maps for Garmin handhelds (Oregon, series 78, 62, etc.) should try OkMap that can be downloaded from this website
Excellent GPS mapping program and a good value.

Pros
Works well and relatively easy learning curve. Nice PDF owners manual.
Cons
Would be nice if more of the advanced features were available in the shareware version. The non-shareware versions are relatively expensive in my opinion. Don't know yet if the additional features are worth the added expense.
