Some sounder shots

G'day guys, I thought I'd throw up a couple of sounder shots for shits and giggles and see how you guys interpreted them. Im happy with the bottom two, being a school of bait and a couple of fish but I would like some opinions on the first one. I've come across this ground a few times and always in the same spots, so it would be interesting to see people's interpretations.

 I think your gain is set too high, try bottom lock and differentiate what's off the bottom. The last shot looks promising.


Love the West!

My 5 cents worth

Mon, 2017-03-27 12:21

My 5 cents worth:

1. Cave or overhang - the up/down pattern is a bit weird.  Was there a bit of chop that day causing the boat to rock? I'd fish this!

2. School of fish which i'd say would be over sand or light weed.  IMO - white line is too strong, dial it back a bit.  When i go over sand, there's no white line and no tail under the bottom echo (gain slightly too high).  As the ground gets harder, white line and tail appears.

3. Bit of ground - Personally, I don't think you're too far off with the gain because if you're over some harder ground, you'd expect to see some softer stuff on top (ie the weed), before your harder echo (the rock).  I reckon you're overcooking the white line, unless you're over granite.  I prefer the scroll speed you're using in this shot.

Water temps are pretty low. Where are you fishing?

Cheers or the replies.

It was an extremely calm day in the first photo and it was taken while drifting. I have been to this spot numerous times and I always get the same reading.

I usually do run my gain lower around 3 at this depth, but have been trialing it running it a bit higher. Same with running BL most of the time. I should of taken a photo with bottom lock on.

The second photo I caught plenty of bait but also picked up plenty of whiting and good size flathead under the bait school.

The third photo resulted in a triple hook up with two Dhufish landed.

What level are people running their white line at? My temp is reading about 2 degrees low at the moment, I'm fishing Perth waters, I just have to recalibrate it.

Once again thanks for your replies.
