Thought I'd post the following tidbit here as opposed to starting a new thread. It is a feature of DiveLogDT (and the phone app also) that was present before, but with only one option.
For each dive site (location), you can use a "Lookup" button to find the the GPS coordinates as long as you have the name of the site - including your location helps narrow it down - for example "Mitch Miller's, Grand Cayman." DiveLogDT uses either DIVEBOARD or Google to find the coordinates. DIVEBOARD coordinates, if available, are put in by other users of that app. You can also click on a link that takes you to the DIVEBOARD page that has info about the dive site. Before the Lookup feature, I was either putting coordinates in from what I could find or using a GPS map of some sort to guess where a site was.
Once the coordinates are in, you can click on (touch link on phone) to "Map It." This feature has been available for awhile. It will take you to a Google map showing the dive site. The DiveLog DT (and phone app) also have a link to a map that shows dive flag pins of all of the dive sites that you have GPS coordinates in for.
