It’s been a while since I’ve done a review of a GPS device for Nikon DSLR cameras. The main reason is that I haven’t seen much movement or innovation in this space. The second reason is that I had kinda moved on to using my iPhone 5 as my GPS and creating .GPX log files that can be read by Lightroom 4/5. Since I always have my iPhone with me I could always just fire up the Geotag Photos Pro App and start recording my movements to a log file. With that said, there are some definite advantages to having a physical GPS device on the camera itself. First of all a physical GPS device will be more accurate. Logging apps only update based on a predefined interval. The next advantage is that a physical GPS just needs to be turned on. In a matter of seconds it locks on to satellites and away you go. Lastly, the logging apps on your smartphone will drain your smartphone’s battery sooner. Not to mention that there is no post-processing with a physical GPS. The longitude and latitude are written to the metadata of the images as you capture them. Yet, I was still using my iPhone more than the physical GPS devices I had. I think the biggest reason for this was the design of the GPS units I’ve used to date. Nikon DSLRs have direct support for external GPS units. On the more recent models like my D600 there’s a dedicated GPS port. Almost all of the GPS units I’ve used to date attached via a cable. This short cable plugs into the Nikon DSLR and the other end attaches to the GPS itself. This is what I never really liked. You either had to attach the GPS to your hotshoe or to your camera strap. The cable was always in my way. I was either constantly knocking the GPS out of the hotshoe or putting stress on the port that the cable was plugged into.
The Eco ProSumer GPS (pro-s)
The Eco ProSumer GPS is one of the latest models from Dawn Technology. First off the thing that attracted me to this model was the fact that there is NO CABLE. It’s small and plugs right into the side of my camera. It’s not in the way! Like the previous Dawn models it allows you to use it in auto mode or always on. In auto mode it will turn on/off with the camera. So then what else is new besides the design? It’s lightweight at only 16g. It’s very power efficient at 19mA (1/3rd of the aging Nikon GP1). It’s also faster at acquiring a GPS lock. Basically it’s better in every way. There is a port on it that allows you to connect a cable release, and of course Dawn Technology sells those too.
