the geotaggers n1 and pro only difference is data logging and pitch and roll? not sure on the pro what “Switches On/Off, Up, Down ” means compared to the n1 “Switches on/auto/off” is obvious. and the pro is strictly powered by its internal battery where the cheaper n1 is internal and camera? http://www.flickr.com/groups/geotagging/discuss/72157617589900045/

easytagger is the only one with alt. ooks like the camera battery actually recharges the internal battery, do the others do this and were just left off the feature list? can this be used on the strap? looks like its either on or off manually seperate from camera, and no remote socket.

So in a nutshell what you’re going to get is the position you’re in with decent accuracy recording to the metadata of your file. If you need more than that you’re going to be disappointed.

Also I haven’t seen one with pass through capabilities for a d90.

You should also look at the more recent review I’ve done here:
http://terrywhite.com/techblog/archives/786

with the di-pro (or any other unit) on the strap, i understand how all the rest of the data would be unaffected, but the heading, wouldnt the unit need to be facing the same direction as the camera?is that possible with the direction you put it in the strap?

at a minimum, i want heading on top of the lat/long, and use of my remote, easily replacable without a proprietary connector special to that gps. after that, all the extra data looks really intriguing if the price difference is negligable. altitude sounds really neat. recording city/state/country would be a huge time saver to me.

without knowing any more than ive read on this and a couple other pages, i’m entrusting you to help me with a large (to me) financial decision i’ve related everything i can think of that i’m looking for in a unit, and hoping you can overlay that on your existing in depth knowledge of each one. i guess from what i know it comes down to Solmeta Geotagger Pro, di-gps pro, and easytagger. could you elaborate more on why the di-gps pro is your favorite, and possibly compare what i’m lookig for plus the techincal things like sat aquisition time, etc, reliabilty over lifetime of the three, or even suggest other possibilities?

i started searching google shopping for d90 gps sorted by price and came up with all these different things… i really need help (including my above post) these are the order i found them in by price – Columbus nGPS, Phottix Geo One, yongnuo n-981/n-1, Promote Systems GPS-N-90, Promote GPS-D90, nikon gp-1… none of the other ones even showed up. i changed the search to nikon gps and got these in order lowest-highest (dont know how many will even work with the d90) – Macsense GNC-35 Geomet’r (no d90 support??), Columbus nGPS, Wolverine GEO, Phottix Geo One, Promote Systems Gps-n-1, GPS (Geotag) Receiver for Nikon (yongnuo n-981/n-1), Macsense Geomet’r GNC-35, Promote Systems GPS Receiver GPS-N-90, Promote GPS-D90, JOBO PHOTO GPS, nikon gp-1…… still none of these other units mentioned in this page.

also, besides lat/long will it add the city/state/location/country in metadata or leave it blank and you have to fill them in manually?

these models i see come with locking wired remotes, many seem to be other than the standard connector. do any units use the original connector for passthrough?

do any units show # of satellites its connected to?

Yes, my favorite is the di-GPS Pro model. I’ll be reviewing their latest ones in a few days.
Whether I put it in the hotshoe or neck strap, it hasn’t been a problem
Accuracy has been very good. I haven’t seen any that are more accurate.
It writes directly to the files and I shoot in RAW 99.9% of the time.
The di GPS Pro offers a 10 pin terminal pass through right on top of the unit. So you can use it and say a cable release at the same time.

The new models which I will be reviewing this week offer the feature of remembering where you are and therefore working inside of a building. Also the di-GPS pro can come on and shut off with the camera.

It is for the reasons above, that it is my favorite. Stay tuned to this blog for the new reviews.

i’m interested in finding out more about this Easytagger, but when i google it tons of crap come up. is there a model #? who makes it? can someone compare it to the Solmeta Geotagger Pro? why do they offer a car charger for their geotaggers? doesnt it run off the camera battery?

what about other models not mentioned in this page? it reads like terry white also liked Dawn Technologies di-GPS,

with all gps units, how does the heading data work with the unit put on the neck strap? i always have something else in the shoe – a flash, popup flash diffuser, bubble level, something thats not a gps. also, what happens when i want to use a wired remote? passthrough? y splitter? that splitter would add another cost to consider between models.

are there any models that come on automatically when the camera comes on?

is there ultimate comparison page with features/ accuracy/ amount of data / prices/ saving last position onto indoor shots/ record to raw/ etc? would someone care to put something like that together?

Interesting results, actually a little surprising. Based on my testing, I favor the Easytagger over the GP-1 for a few different reasons, mainly the Easytagger’s better functionality and value. There are a couple of watchouts to consider with the Easytagger as well, but these are things I can live with based on my shooting priorities and preferences. The Garmin Geko that I had so proudly rigged up a few years back really sucked, as it turns out. I thought it would have blown the doors off the others on a technical basis, and get knocked for its bulk and weight, but it didn’t even pass technical muster. Interesting results with lots of details.
I’m curious to hear what other people may have to say based on their experience with any of these GPS units or others. Take this for what it’s worth. I’m not a professional electronics tester and I’m certainly not a professional photographer. I was just really curious so I figured I’d at least experiment and share my results, and see if others found value in it.
Today I took my Easytagger out in the field to test it out on a long hike through the woods. The Easytagger did take a few minutes to acquire a good signal, but once it locked on, re-acquisition was nearly instantaneous over the next few hours, and the unit never failed to acquire. My photos were all successfully tagged after the unit had initially locked on. My exif data shows that I was locked onto 8 satellites for most of the day.

After I got home, I took the time to install the included Lockr GPS software, which enabled me to easily read the tracking data and plot my path on a map (using either the Lockr map or Google Earth). I’ve got to say the Easytagger tracker function is amazing, maybe even scary! I didn’t realize that it had been tracking my movements every moment it’s been turned onto the “All” position since I received the unit a week ago. Wow, it shows me driving to my daughter’s house for Thanksgiving dinner, then walking around her neighborhood to work off a big turkey dinner (brought my camera with me on that walk). Today’s hike through the woods was also recorded. It shows every trail my wife and I took, and even the deviations away from the trail where we saw some interesting things to photograph off the beaten path. It even shows the path I took right before I put the GPS in the car and turned it off. It shows how I walked to the trunk of the car, spotted an interesting peak on a building, walked up to the building to photograph it, then walked a few feet away to get it from a different angle, and then return to the car. Using the satellite view, it shows the exact parking space I had used (you can see the lines in the parking lot). The accuracy of the tracker feature is impressive. Sure, every now and then it shows a deviation of a few feet (3-6 feet?) off the actual path I took, but this is probably where the unit was extrapolating between data points.

The more I use the Easytagger, the more impressed I am with it. Anyone want to buy a brand new, hardly used Nikon GP-1?

It combines data logger and direct input together. Also built in 3 axis compass and level indicator.

Would love to hear back from anyone that knows about this or has tested the gps while in motion other than walking.

Thanks!
