You can download (export) raw bathymetric map data in .csv format. This feature is available for all Deeper sonar models except Deeper START.
There are 2 ways to download bathymetric map data:
1. Via Fish Deeper Web. In Fish Deeper Web, select the map that you wish to download, and access the menu of the map (click on 3 little dots). Then, select "Download"
2. Via the Fish Deeper app. Click on 3 dots near the name of the scan, and then select "Export scan data as CSV"
Exported data appear in .CSV format that will contain such values as latitude, longitude, depth and a timestamp. Timestamp will appear as the number of milliseconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970. (UNIX Time). Coordinates are in WSG84 standard.
GPS records latitude and longitude values approximately every second, thus you may see those data values indicated as 0 - which happens if the depth was recorded, but the coordinates were not. The sonar itself scans about 15 times per second, this is why most data lines are without coordinates.
It is only possible to export bathymetric data created in Boat, Bait boat or Shore modes of the sonar. Recordings made in Standard and Ice Fishing modes will contain only the sonar data, which cannot be exported.
Note: There are multiple ways you can convert timestamp to normal time. If you're using Microsoft Excel, you can use the following formula:
=(D1/86400000)+DATE(1970;1;1)+(X/24)
X= required time offset from GMT time. For example, if you're based in Lithuania and it's winter time (GMT+2), the formula would look like (2/24)
Then, format Cell to "Custom", in "Type" yyyy-mm-dd hh:mm:ss
