Dear Reefmaster and Forum: I would like to ask for some information on .sl2 files and on exporting to a .csv file. In particular, under Track Properties the Sonar channel information shows, for a 54 minute recording made with a Lowrance HDS9 sounder to which a 3 in 1 transducer and a TM260 6 degree 200 KHz transducer is connected, 5 channels, Secondary, Primary, Downscan, Sidescan Port and Sidescan Starboard. The ping rate is shown at 16 per second for all 5 channels and about 52118 as the number of pings for each channel. Exporting the track to a .csv file results in 13,289 lines which is about 1/4 of 52118. Which of the channels is exported or is the export a combination of some or all of the channels? Does Reefmaster combine and average the raw ping data before it is exported? Is one able to select which channel should be exported? Thanks.
