James:

Do you plan on using it for land navigation purposes, for geo-tagging photos, or both? I have a JOBO photoGPS that sits in the hot shoe and works extremely well for geo-tagging images, but that is all it is good for.

The biggest positives are:

1. It is extremely fast and accurate in the field.

2. The software is very fast and easy to use.

The biggest negatives are;

1. You need an internet connection to geo-tag images rather than having the mapping data on a file on your own computer. The unit will store at least 2,000 or 4,000 locations depending on the model and you can save its contents to a file on your computer/laptop for later use when you do have an internet connection.

2. It only writes the gps data into the EXIF data for jpeg's. It creates a sidecar file for RAW files.
