GPS for divers



The GPS antenna for divers allows the use of all devices equipped with GPS, such as: cartographic devices, cameras, camcorders, mobile phones, tablets, etc. (of course all of them must be supplied with a special watertight diving protection, suitable for scuba diving).

For the connection between the GPS antenna and the machine body of the aforementioned devices, no type of electrical connection is required via cables or plugs, but simply through simple physical contact or through the approach between the device (e.g. the GoPro 5 equipped with GPS ) and our GPS Antenna for Divers (just bring the two units together to establish an induction connection). The operating scheme of the GPS antenna for scuba diving is as follows:

1) Receiving apparatus positioned on a buoy on the surface (see detail n.1)

2) Data transmission cable that connects the buoy to the submerged transducer (see detail n.2)

3) Submerged transducer, that transmits the signal which is received up to the device you are using (Gopro, mobile phone, GPS, tablet, etc.) by physical contact (see detail n.3)


The receiving apparatus (see detail n.1), must be positioned on a buoy on the surface, which must be kept almost on the vertical of the diver (the position indicated will be that of the buoy, and not that of the diver, for this reason it is necessary the verticality of the cable.

The small drift of the buoy, when greater precision is needed, can be calculated and compensated.

The submerged transducer (see detail n. 3), which is located on the camera’s supporting plate attached to the cable holder (see detail n.2), must be flanked and locked to the cover of the device that you are using (Gopro, mobile phone, GPS, tablet etc …) corresponding to its internal antenna.

Possible uses:

1) During the dive, the coordinates of a submerged object (wreck, remnant of war, lair, archaeological find, etc.) must be read on the GPS and marked on a slate.

2) Photograph the object (with a camera provided with Gopro 5/67/8 type GPS or iPhone 5/6/7 mobile phone, Android, etc …).

3) Videotape the path of the diver and of the submerged objects (wreck, war remnant, lair, archaeological find, etc …)

4) During the dive, view the preloaded cartography, by using tablets equipped with internal GPS such as Ipad, GPS cartographic equipment, etc. … (supplied with a special watertight diving protection and provided with watertight keys for use)

Photo mode:

In the case of photos, the coordinates of the submerged point are automatically stored under PROPERTIES (Exif) and the photo becomes geolocated.

Through a special software the submerged point will be automatically displayed on Google Earth.

With the same software, the coordinates of the submerged point are read and used for the intended use.

Video mode:

In the case of a video, the coordinates of the submerged route are automatically memorized and the video becomes georeferenced).

Using some special softwares, the georeferenced submerged path will be automatically displayed and the coordinates of the submerged points can be read using them for the intended use.


What does Exif mean?

Exif is an acronym for Exchangable Image File Data.

It contains information pertaining the data as regards to the taking of a photograph and those relevant to the image taken. At the time of the photo shoot, the Exif data is recorded on the same file as the image taken. If the camera is equipped with GPS, the coordinates will also be stored.

Thanks to the numerous software and applications available it is possible to read the coordinates of the point where the photo was taken.


Example of Geolocated Photographs, through the use of the GPS Antenna for Divers. Photos that you take during the dive with Gopro 7, inserted in the Google Earth map automatically through the use of a specific software
