Understanding Contour lines

[bam bam]

Hello fisherman

Im hoping someone can share their knowledge so I can better understand what to look for in contour lines when using a GPS/Sounder/Sonar.

I understand the basics of what the lines represent and the numbers associated with them, its more the fact I have no idea of what to look for when I'm trying to find a spot where fish might be hiding.

Maybe I'm right saying different species of fish choose to hang out in completely different spots ??

To narrow down any helpful response, say if I wanted to target snapper, kingfish, and flat head in and around Sydney Harbour and Northern Beaches, am I looking to drop my line where the ground is relatively flat ? or where the ground is quickly dropping away ? or not ?

Thanks fishos !

Best advice I can offer, find the bait and you find the fish! Most fish will tend to congregate around structure even of its a slight rise off the bottom. This time of year I would target snapper on the inshore reefs early morning and late arvo and deeper reefs during the day. Hope that helps!

Cheers scratchie!!!
