Dawntech of Hong Kong has renamed their product from N2-diGPS, which I also bought about a year ago, to Dawntech Basic which by the way has no on-off switch like the old N2-diGPS and Pro which is waterproof and has a ten pin input.
My Dawntech N2-diGPS.
The other version is named USB for Canon camera.
Check out the Dawntech website.
Solmeta of China has introduced the new DP-GPS N2 which is able to geotag the last known coordinates if the signal is lost or when you’re indoors. Priced at US$288.
