Q: I just purchased your gps + remote for my Nikon camera. The manual talks about a mobile app. Looked for it on the Apple App Store to no avail. Does it exist? if so, how do I find it?
-
Thank you for your purchase. The page where you left this message is actually the app download page. You can download the Android APK directly from here https://prazisolutions.com/prazisnap/prazisnap.php . However, an iOS version is currently unavailable.
The app requires background execution permissions to continuously track your location and send it via Bluetooth Low Energy (BLE). Due to Apple's tightening restrictions on background permissions in recent iOS updates, maintaining this continuous connection is exceptionally difficult. In fact, our hardware was specifically designed and built to overcome this exact limitation.
Q: Yesterday, after an overnight charge (there was no red light), the unit worked fine for an hour then it stopped working. No lights or anything. I now have it charging but there is no indication that anything is happening - no lights at all.
+
Based on your description, it seems like the unit didn't charge successfully. Are you using your phone's PD charger? Please try switching to our included charging cable and connect it to a standard USB-A port, such as a computer's USB port, to see if that works. The red light must be on to indicate that it is charging.
Q: Hello I purchased an R-Type some time ago but cannot get it working properley on a D500，it will remote trigger but no GPS Exif Data, but it works properly on Z8 do you have any experience or ideas, my researches havent lead to any success？
+
Thank you for your support. Since it works well on the Z8, it means there is no problem with the product itself. May I ask where you purchased your D500? If it was bought in mainland China, or if it is a second-hand camera originally from mainland China, then this is not surprising. This is because Nikon cameras sold in mainland China after 2015 have their GPS functions blocked.
Q: When is IOS version of Photography Assistant coming out?
+
The Photography Assistant functions quite differently from standard apps, as it requires continuous background location tracking and persistent Bluetooth communication. Given Apple’s increasingly strict control over these background permissions, ensuring long-term stability for a third-party app across different iOS versions has become nearly impossible. This technical reality is exactly why we prioritized a hardware-based approach from the very beginning. By opting for a dedicated hardware solution instead of relying on an iOS app, we are able to provide the consistent and reliable GPS data collection that photographers require, which simply cannot be guaranteed through software alone. Currently, we have suspended any further development on the iOS version to focus on the reliability that only our hardware can offer.
Q: I’m in the UK; where can I buy the GPS unit for a Z8, please?
+
For all customers outside the U.S., please leave your contact details and shipping address via email or our online contact form (all messages are private). We will provide a quote based on your location and send a formal invoice with payment options (US Bank Transfer or PayPal).
Generally, our direct shipping is both faster and more cost-effective than international forwarding services through Amazon or eBay.
Q: Does the GPS unit work with the Bluetooth in the Nikon Z-50ii and Z-5ii without using your S-adaptor?
+
I'm afraid not. Nikon removed the accessory terminal on the Z50II and Z5II, （along with Zf,Z30 etc.）so there is no hardware port to plug in a GPS unit.
Q: I plan to go out into the wild with 4 Nikon D850s. If I put a receiver on all 4 cameras at the same time do I only need one transmitter to send the GPS coordinates? This will only work if all the receivers use the same frequency.
+
Regarding "One-to-Many" Customization
The "broadcast" solution (one transmitter for multiple cameras) is technically possible but would require chip-level firmware customization. Since standard Bluetooth is a point-to-point protocol, creating a dedicated "one-to-four" sync system would involve significant R&D costs and time. Currently, there is no off-the-shelf product on the market that supports this specific behavior.
The Major Disadvantage of Broadcast Protocols
One critical reason we have decided against a broadcast-only (One-to-Many) architecture is the lack of a "Handshake" mechanism. In a broadcast mode, there is no secure, exclusive pairing between the transmitter and the receivers. This means that in a professional shooting environment where other photographers may be using similar equipment, your signal could inadvertently be received by their devices, or vice versa. This lack of isolation creates significant potential for signal interference and data crosstalk, which is unacceptable for professional assignments.
The Most Reliable Field Solution
In practice, the most efficient approach is simply to equip each of your cameras with its own dedicated GPS set. This provides 100% redundancy and secure, paired communication for each body. You won't actually need to "manage" or "monitor" them throughout long shooting days. Once the adapters are installed and the units are switched on, they function independently. Unlike many wired solutions, our adapters draw negligible power from the camera body, and the GPS units run on their own dedicated batteries, so you can leave them running without any concern for your camera’s battery life.
Exceptional Battery Performance & Redundancy
Our Main Units are built for long-haul assignments. A single charge provides over 36 hours of continuous operation. Even when the red light starts flashing, you still have 2–8 hours of buffer. By having multiple complete sets, you have a massive power reserve to rotate between cameras and chargers without any downtime. This independent architecture ensures that if one unit were to be damaged or lose power, your other camera bodies remain fully functional.
Pricing and Direct Invoicing
Due to the significant platform fees and tax collection policies on marketplaces like Amazon and eBay, it is challenging for us to offer our most competitive pricing there. However, if you are purchasing directly through our official website, we can provide more professional and flexible quotes for bulk or studio orders.
Please provide your email address via our contact form. Our team will generate a formal Bank Invoice and send it directly to your inbox for a secure and professional transaction via Bank Transfer (ACH or Wire).
Important Note on Communication
After we send an invoice or technical brief, please check your Spam/Junk folder. Automated business emails from our banking system can sometimes be filtered by aggressive mail servers. To ensure a smooth transaction, we recommend whitelisting our domain once you have initiated a direct request.
Q: I want to use this GPS with a Nikon D850. In addition to recording co-ordinates on each photo, can co-ordinates be quickly viewed while in the field?
+
Real-time Data Viewing: Once the GPS unit is connected, your camera will automatically embed the latitude, longitude, altitude, and UTC time into the EXIF metadata of every photo you take. You can quickly view these numerical coordinates directly on the D850’s LCD screen while in the field. To do this, simply enter Playback mode and press the "Up" multi-selector button twice to cycle through the photo information displays.
Map Visualization: While the numerical coordinates are viewable on the camera, displaying the actual shooting locations on a map requires importing the photos to a computer or a smartphone. Standard photo management software (such as Nikon NX Studio, Lightroom, or mobile apps) will recognize the embedded EXIF data and pinpoint the exact locations on a digital map.

Q: The Prazi GPS uses a lithium-ion battery; although I assume it has a long lifetime, I'd like to know how difficult it would be to replace the battery sometime in the future. I'm familiar with doing this kind of thing with various consumer products, including soldering if needed.
+
That is a great question. I completely understand wanting to ensure your gear stays functional for the long haul.
Why You Likely Won't Need to Replace It：
We designed the Wireless 2nd Gen with significant "performance redundancy." A major reason the unit is larger than the 1st Gen was specifically to accommodate a much higher-capacity battery.
Extreme Efficiency: We have optimized the circuitry to run on extremely low power. Even with high performance, the power draw is minimal.
User Feedback: According to feedback from our current users, many find they only need to charge the unit once every one or two months under normal use.
Runtime Specs: The unit provides over 36 hours of continuous operation on a single charge. Since typical use cases rarely exceed 6 hours at a time, even heavy users can expect 4–5 days of life easily.
The 5-Year Horizon: Given these low-cycle counts, you shouldn't have to worry about battery health for at least 5 years. Even as the lithium chemistry naturally ages, the device remains fully functional; it would simply require slightly more frequent charging rather than becoming obsolete.
If You Ever Decide to Replace It：If you eventually decide to swap the cell, it's quite manageable with your experience; there is actually no soldering required.
Difficulty: It is much simpler than a smartphone battery replacement.
The Trade-off: The main task involves prying the casing open. While the internal electronics are easy to work with, please note that re-gluing the housing might slightly affect the original "factory-perfect" look, though it won't impact functionality.
In short, we’ve built this to be a "set it and forget it" part of your workflow!
Q: I just learned about your GPS product. A question: I use an L-bracket on my Nikon Z6III. How can I determine if your Bluetooth BLE adapter will fit my camera with the L-bracket attached?
+
Thank you for your interest!
Our adapter plugs into the camera's "Remote-GPS" port. Since L-brackets vary significantly by brand—some leave ample room for accessories while others block the port covers—we cannot guarantee compatibility without more details.
To help us give you a definitive answer, could you please email us at info@prazisolutions.com with a few clear, close-up photos of your camera with the L-bracket attached? Specifically, a side view showing the port covers would be most helpful. Once we see the setup, we can determine if there is sufficient clearance for the adapter.
We look forward to hearing from you!
