Shore fishing in different conditions – Piers and docks, river fishing
You can use your Deeper Sonar for fishing from the shore, from piers, docks and bridges (including in salt water), and on rivers. But you will need to adjust your set up and approach.
For casting from docks, piers and bridges
Make sure you attach your line to the middle attachment point of the 3 attachment points on your Deeper (this does not apply to the Deeper START, which only has one attachment point). Using one of the other attachment points will result in the sonar sitting in the water at an incorrect angle.
Deeper Sonars are suitable for use in salt water, so go ahead and use yours off a dock in calm conditions. If the sea is rough, this may affect connectivity to your smartphone.
For casting in rivers
Deeper Sonars are suitable for finding depth levels and features in rivers, provided they are not very fast flowing. Use the same attachment points you would use for lake fishing (bottom attachment point from the river bank, middle attachment point from a bridge or pier).
The most effective use of your Deeper Sonar when river fishing is for finding depth and features – when the currents are fast, accurately marking fish can be difficult. Using the current to drift your Deeper Sonar down the river is often an effective way to cover areas of your river. If you are using a Deeper PRO+, we recommend using the Onshore GPS mode (Settings > Onshore GPS), as this will give enable you to map the depth of the river as your sonar drifts.
If you are using the Deeper PRO or PRO+, it is recommended to use Narrow beam (290 kHz) for higher accuracy of the mapping. If you are using the Deepe CHIRP, we recommend using High CHIRP or Mid CHIRP for higher accuracy of mapping.
