In my work I have a periodic need for exact locations for photos. Sometimes for licensing, documentary, follow up, legal, real estate.... Many photographers need exact location data to document where and when a photo was taken. Sometimes years can pass between the time a photo is taken and a follow up, or license agreement requires a return photo and precise location is needed. Prior to 2019 many cameras had built-in GPS which provided geotagging in the EXIF files. Now however, there are only a handful (Canon D5iv, Nikon Z9, X1D II 50C...) now have geolocation capability. I'll insert here that I have zero company affiliation with any of the GPS tagging products I will mention herein (or anywhere else).
Today camera manufacturers want us to use their apps to provide geotagging. I'm not sure whether that provides them with information on where we are shooting but........ The issue with many of these phone apps is that they work intermittently at best. The alternatives are make written notes which, for me doesn't work as I can be on the move and stopping to take notes can mean the difference between getting the shot and missing. A third method is to use one of the many tracking devices like Garmin tracking/hiking recorders that plot where you have been and can be synched to your photos during post production. The two faults I have with these is most of these recorders leave bread crumbs to identify your past positions, not continuous recording to save batteries. They also require you to upload everything to a computer after the shoot and hope that the data was recorded successfully and synchs to your photos. Even in the best of results you get an approximate location of where a photo was taken and not necessarily an exact location. That leaves a fourth option - third-party geotaggers like; di-GPS Geotagger Eco, Columbus NGPS, Nikon GP-N100... and a few others. The issue with many of these is that they were developed for older Nikon cameras and don't work on newer mirrorless cameras like Z bodies. Some are also the size of a remote flash transmitter sitting atop your camera any time you are logging data. Additionally many require being mounted on the multi-shoe and occupying that space and/or having to be tethered to the camera via obtrusive connection cables that run from the GPS receiver to the camera body.
After extensive research and trial of several of these units I stumbled upon the Prazi Solutions GPS Transmitter & receiver. The transmitter can be attached to your strap, worn around the neck or even "fobbed" to your belt or pack straps. The receiver plugs securely to your cameras 10-pin plug and locks into place. To operate, charge the transmitter, plug in the receiver, turn on the transmitter, allow a minute or two (cold start) for the transmitter to lock onto 3 satellites and connect to the receiver - and shoot. No in-camera adjustments or settings. Nothing on your camera changes except the small +/- 1in. receiver. It's on continuously and draws near zero from your in-camera battery. In usage I've found zero lost/missed logs and even if you go into a canyon, between buildings or anywhere the transmitter temporarily loses satellite connection you get a geotag from your last known position until connection is reestablished. To verify that you're getting your logs simply look at the blue-green flashing light on the transmitter to verify it is currently connected to satellites.
I've found that every different software Apple, LR.... shows the data differently so you will have to see how your software handles your EXIF data. I'll attach some photos of the product and contact information herein. I purchased mine from Ebay (prazisolutions) and you can search by title: GPS unit for Nikon Z8 D850 D6 D5 D4 D3 D810 D800 D700 etc. with wireless remote. You can look up the company at: Prazi Solutions LLC
