Geotagging photos is a fantastic feature that allows you to see the location where each photo was taken. This is particularly useful for organizing your photo albums and reminiscing about your travels.

When browsing your photo album on an iPhone, you can easily view the location where each photo was taken. This feature helps you find photos based on their shooting location.

The ability to display the shooting location is thanks to the EXIF (Exchangeable Image File Format) data embedded in the photo. This data includes the GPS coordinates where the photo was captured.

However, most cameras do not record the photo's location, because of battery consumption. The camera can enter sleep mode when there is no operation, but the GPS module needs to continuously lock onto satellite signals when working, it will consume battery power continuously.

In fact, many cameras, especially Nikon's DSLRs and Mirrorless models, support geotagging through external GPS receivers. These devices provide accurate and responsive location data, but they come with some downsides:
---They are bulky and require an external connection.
---They occupy the camera's hot shoe.
---They consume the camera's battery power.

Newer Nikon cameras can obtain geolocation data via a smartphone app. This requires a constant wireless connection, significantly increasing battery consumption for both the camera and the smartphone. Additionally, only the latest models support this feature.

Prazi has been developing GPS unit for Nikon digital cameras for 18 years, with multiple product upgrades. The latest product is the second generation of the wireless version, offering an excellent balance of functionality, performance, and power efficiency:

• It supports almost all Nikon DSLRs and Mirrorless cameras.
• The camera only requires a low-power Bluetooth adapter, which hardly drains the camera's battery.
• The GPS receiver comes with a large-capacity lithium battery, providing over 36 hours of continuous operation on a single charge.
• It offers high positioning accuracy and timely updates.
• It can also function as a wireless shutter release.
