Sounders








Welcome to Gold Coast Fishing
How to read your sounder

On this page you will find some sounder screen shots and general information about sounders.

I suggest that anyone wanting to get to know their sounder better should read the following tutorial on Sonar, found on Lowrances website. HERE

 

In this screen shot, you will notice that the water depth is 33 meters. The bottom is shown clearly, with excellent holdings of fish down deep. In this case they were Tailor. It is very common for Tailor to hold near the bottom. If the soundings were in more mid water they are often bait fish. In this instance we caught several mac tuna that were feeding on the Tailor and Yellow Tail that was mixed in with them.
This is a typical screen shot of a live bait ground. Tailor & Yakkas, congregated over a reef. It makes getting livies easy when they school like this.
Again these are livies congregated over reef. On this occasion, the speckles mid water are Slimy Mackerel. Usually when livies school up like this, Tailor & Yakkas down deep, with Slimy Mackerel up top as seen here. We were able to decide which live baits we wanted by the depth of our baits.
This is a Garmin FF240 Blue. Using 200khz transducer, and 240x240 pixel resolution, you can easily see the fish holding over the reef bottom and Wireweed.

Note the reflection under the gray line. This is Wireweed.

My Lowrance X88DF showing a nice piece of reef with some fish hugging the drop off. The fish in question are snapper. You can notice from the grayline that the bottom is reef and that there is some coral and spounge growth as depected by the spectalled appearance underneath the grey line
Also on my X88DF, this shows the difference between sand and reef. On the left is sand, notice how thin the greyline is, then see how it changes as you come up onto the reef, with a thicker greyline and specals underneath showing growth. Also don't forget the great showing of fish. Once again these were snapper.

Very busy screen this one. Clearly showing a baitball being hammered by larger predators. You can see arches all around the ball. The clear bit in the actual baitball is where a predator has scattered the bait. The bottom show reef with some sponge & soft coral growth. The 2 parallel lines on the left of the screen at roughly 17m, is my live bait. deliberatly set so it was in the strike zone.

About 30sec after this pic was taken the livie was hammered by a Cobia.

Dual transducer at work on a split screen. Excellent shows of fish down deep. These were kingfish, amberjack, samsonfish, pearl perch, squire, Cobia... I could go on. A good lot of surface clutter on the screen up top is normal, as I had the gain set fairly high so I could get a good view of the bottom. On the left we have th 50khz transducer & the 200khz on the right. Notice the bottom, is once again reef, but see how the under side of the grey line is very fuzzy. This is wireweed.
Bait schooling at its finest. Wall to wall bait & the Marlin were on the chew. Bottom is hard reef, with some growth.
Same bait school. You can see the larger fish hanging around above the school
