GPS connection and use
Smartphone / tablet GPS
The Deeper App uses your smartphone or tablet’s GPS for a variety of mapping functions, including bathymetric mapping as you troll, saving the location of your scans, and GPS Ice Hole Marking. For these functions your smartphone / tablet needs to be within 3ft / 1m of your Deeper sonar. If the devices are far apart, the location information for your sonar readings will be incorrect.
Inbuilt GPS (Deeper PRO+)
The Deeper PRO+ has an inbuilt GPS receiver. This means that these models do not need to be in the same location as your smartphone in order to create maps, so you can map by casting it out.
When you have selected Onshore GPS mode, look for the satellite icon in the top right corner of the map. The color of the satellite icon indicates if a GPS connection has been established:
- GPS found means your Deeper GPS location has been fixed, and you are ready to start mapping.
- Looking for GPS means your Deeper is processing satellite information and currently the location of your device is either unknown or not precise enough for mapping. If it does not change, please follow the troubleshooting instructions.
- If the “Looking for GPS” status doesn’t change to “GPS found” for a long time, this could be because your Deeper is indoors or under the roof of a boat, because the device is submerged, or because the surroundings are blocking the GPS signal (for example, in a gorge or a mountainous area). If nothing is blocking the GPS signal, please follow the troubleshooting instructions.
Maximizing GPS connectivity for Onshore GPS mode
There are some steps you can follow to improve the GPS connection when using Onshore GPS mode:
-Give your Deeper time to establish a strong GPS connection. The GPS receiver in your Deeper has to connect with satellites orbiting the earth, and this connection may not be instant. Furthermore, the availability of these satellites can vary on different days, which means establishing a strong GPS connection can be fast one day and slow the next. We recommend putting your Deeper in the water, enabling Onshore GPS mode, then waiting for 5-10 min before casting it out.
-Check if the status of GPS is green. Once your Deeper has established a good GPS connection, the GPS status will be shown as “GPS found”. After casting out your Deeper, please double check the GPS status. If it has turned back “Looking for GPS”, wait a few moments for the GPS connection to be re-established.
-Check the conditions and surroundings. GPS signals can be affected by weather conditions and obstacles. The signal may be weaker if there are heavy clouds or rain. It can also be blocked by overhead obstacles like branches and power lines.
