My experience too. Not sure what the other two systems add to it. As far as cell towers much of the time there is no cell coverage. If I’m accurate to 100 yards that is plenty good

The 5D IV GPS was more than adequate when I used a bunch of them from the souths of Patagoniads to the norths of Svalbard, and Africa and Central America in between. Not only could it tag the RAW files, but it could create a track log that could be used to sync files from other cameras. Surely 10 years later they could provide a better module with GPS/Gallileo/GLASNOST, etc.

Yep, this "track log" feature is why I think 5D4 basically has a smaller GP-E2 inside. Because GP-E2 also stores a track log into its internal memory.

It's me again, has anybody been successful to connect the GP-E2 to some other camera than 7D using the supplied cable?

I would like to have free hotshoe (of course, I'd need another cable convertor for USB-C RF port), so I tried the only camera that had correct mini USB. i.e. EOS SL2, just for tests, but the camera says the GPS tracker isn't connected, even if it is (and the cable is correctly plugged in camera-camera end tracker-tracker end).

Anybody a success?

Okay. I looked again at my remaining 6D and googled that its A/V OUT Digital connector is in fact also USB, so I tried connect the tracker there and this connection worked.

So it looks like Canon simply doesn't support the tracker on SL2 except the hot-shoe connection. Now I wonder what happens when I get a correct cable and try to connect to R6/2.

Yes, for all R cameras where the GP-E2 is supported, it's only supported via the hot shoeYes and USB won't work. In typical Canon fashion, one has to look hard to find that info: https://cam.start.canon/en/H002/accessory_0120.html

Note: the info in that table about the supposed requirement of the AD-E1 adapter on modern R cameras is only partially true. The AD-E1 is required if the rubber gasket on the hot-shoe mounted equipment is in place - which is required for weather sealing. Removing the rubber gasket lets it mount easily on the newer R's. It's possible to mount it with the gasket in place, however it will require a lot more force to lock the GP-E2 and the stress that creates on the hot-shoe could damage the hot shoe mount over time.
I'm using the GP-E2 on my R5 Mark II without the gasket, since I don't work even in light rain and thus don't need the weather sealing on the hot shoe.

I've used the GP-E2 on the R7 and R5 II. I think they want you to use the adapter for weather sealing. It seems to fit ok without the adapter.

Ah thank you. You saved me couple of bucks as I prepared to buy a rare USB-C to miniUSB cable to try (and fail ).

That's not nice, it looks like the only way to combine the geotagger and flash if need be is the smartphonificated way that works on a good day.

I did make some experiments, because I have this AD-E1 thingy (from the times I tried to love R50 and bought R10 later), the 600EX-RT flash first version, and the GP-E2.

I also have the older 580EX2 flash, which I could not mount before on RF camera until someone suggested what you did exactly and after I removed the rubber gasket the flash mounted easily.

With gaskets, AD-E1 mounts easily (who would not expect that, eh), GP-E2 mounts with some force, but the 600EX-RT also mounts as easily as AD-E1. So that got me thinking about switching the gaskets between the GP-E2 and 600EX-RT. Well, the result is, that apparently the gaskets are identical, but there's something in the dimensions of the foot that prevents GP-E2 to mount easily with the gasket.

Then I took a look at AD-E1 gasket... and swapped it on GP-E2. Unfortunately, it's too big, but only from the foot of the device forwards, the rear part is identical. And of course, with this, the GP-E2 fit well. So that got me thinking, that if I can get a holt of a replacement gasket for RF hot shoe, I could perhaps fit it on GP-E2 and fill the unsealed space of the gasket with some flowable silicone or something to get the weather sealing... Why can't we have it easy.

Easy, but somewhat unwieldy way out would be just to use the AD-E1, but that thing is so damn high for its sole purpose IMO...
