GPS (Deeper PRO+)
GPS is an essential component for creating accurate bathymetric maps. GPS accuracy and reception quality can be affected by the conditions.
Heavy, cloudy weather can affect the strength of the signal, while branches, pylons and other obstacles like electricity lines can also affect connectivity, as can the availability of satellites.
These factors can cause the following issues:
- Your Deeper failing to connect with satellites – the satellite icon is flashing red or orange
- Your bathymetric mapping (the depth colors) appear to be drawn on land, instead of on water
The GPS in your Deeper PRO+ connects directly to satellites. So, to ensure rock solid connectivity, we recommend putting your Deeper in the water for around 10 minutes prior to usage to enable it to establish a strong connection. When you are using your Deeper PRO+ for bathymetric mapping, make sure the satellite icon is green, showing that your Deeper has established a strong GPS connection.
Only when the satellite icon turns green can you start creating bathymetric maps. The time it takes for the unit to establish a strong GPS fix depends on the number of obstacles nearby as well as the weather conditions.
If you are using the Deeper PRO+ in Onshore GPS Mode but the GPS connection is never established, please contact the Deeper Support team.
