Dawn di-GPS has just come out with their latest version, the Eco ProFessional 2. The biggest is the addition of a digital compass. What this does is provide you with a Heading, or the direction the camera was pointed when the photo was taken. It also has built-in flash remembering the last GPS coordinates in case you want to apply them to a different photo. For me, this replaces the Eco ProFessional because that Heading every so often would be really useful info. If you’re wondering, yes you can screw in the WR-R10 to the Eco Pro or Eco Pro 2 and it function. Pretty cool!
Note: I’ve had reports of the WR-R10 working and not working with this unit. The reason why it does or doesn’t work is not in my wheelhouse as I didn’t design, build or sell them. Sorry
