I think there could be an app for recording metal detecting tracks in a field etc.
Then user can add a photo and geotag for the find, with a brief description etc.
Similar to geocache but dedicated to Metal Detectors.
There are some phone based ones but something on the 750t would be great.
The tracking could then confirm where they have akleady searched in a field or beach.
Finds could be tagged with an unique ID e.g.yymmdd hhmmss 01 02 etc. For later references etc.
prefer to be able to store the database on device so no need to link via WiFi.
may need a desktop app to import finds etc and add more notes values etc.
new to Garmin and Metal Detecting level one noob!
