Don't we all

Hi Cameron, the contours are the lines on maps and sounders that represent changes in elevation. This is where the fish like to hang out, along the ledges where the elevation plateaus.

@@AFNFishingOutdoors many thanks. Trying to picture a ledge where it plateaus on a contour map is hard for me to grasp. Would it be too much to ask if you make a new video to just focus on this concept alone? It would greatly help me (and others I suspect).. Thank you Cameron

Hi Cameron. The transducer was the new ActiveImaging HD 3-in-1 FishReveal Transducer. The transducer provides 2 types of sonar. The first is traditonal downward sonar which displays the bottom under the boat (and any fish in the water cloumn). This sonar is 2D and uses "High Chirp". This "traditional" 2D, downward-shooting sonar only reveals what is under the boat, therefor you need to actually drive over a wonky hole, or a reef etc before you can identify it, so naturally, this can be very time consuming. The transducer also has "sidescan" which sends a signal out on either side of the boat, so it catches the contours of the seabed from the side. So, much like shining a torch out to your side while walking in the dark, you can see so much more than if you shone the torch directly down at your feet. Fopr example, you could set the sidescan at 30 metres each side of the boat, so that gives you 60 metres of coverage when searching for reef or wonky holes. Note that the transducer sends out both types of sonar at the same time and you can display them both at the same time on a split screen, along with your GPS map.

@@AFNFishingOutdoors many thanks for this detailed response. I understand now.

Cool story bro
