Basics for Boat and Kayak fishing with Deeper
The Deeper PRO/PRO+/CHIRP are suitable for trolling from your kayak or boat using the Deeper Flexible Arm Mount. You can also cast these devices out from your vessel to scan hard-to-reach-spots or to avoid trolling over your target areas. The Deeper START is suitable for casting from your kayak or boat.
Once you have mounted your Deeper PRO/PRO+/CHIRP to your kayak or boat using the Deeper Flexible Arm Mount, you are ready to troll. Trolling at higher speeds (for example, 3.5 mph / 5 kmph) is suitable for getting general depth readings. Slow down to 2mph / 3kmph or slower for accurate fish finding and detailed scanning of underwater structure.
The FishDeeper app uses the GPS in your smartphone or tablet to create bathymetric (underwater contour) maps as you troll. For this function, select boat mode (Settings > Boat mode). You will get a split screen display showing both your mapping and your sonar readings.
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 CHIRP, we recommend using High CHIRP or Mid CHIRP for higher accuracy of mapping.
For scanning, you can continue in Boat Mode (the split screen display will show you scans as well, and you can adjust how much of the screen is taken up by the map) or switch to Standard Mode for full screen scanning display. Don’t forget there are 3 color palettes to choose from (Settings > Sonar > Screen Color Mode).
