#1: settings look really good in this one. To me this looks like a big school of fish... not huge fish but not tiny bait either. I've seen big schools of sandbass and calicos mark like this. Also, over rocky reef areas, you will see ocean whitefish and blacksmith perch look like this. Blacksmith or whitefish would explain why you never got a bite. I've seen big schools of yt look kinda like this, but they would be harder marks with a lot more bright reds and yellows in there. #2: Sensitivity is way too high for that depth, need to dial it back a lot. Tough to tell what is there with all washed out like that, but I think I see your dropperloop or some bait down. And probably some baits and small fish checking it out. #3 setting looks great. here we have a big vertical strand of kelp in the middle, and a couple of good wads of mackerel feeding at about 20-25'. Also some scattered debris and probably rockfish on the bottom. here you should be working that sibiki shallow, they look like good greenbacks or big spanish. #4: shallow water again. Your sensitivity is a little hot, but much better than #2. The big worm in the middle is marking too soft to be a fish. With your gain up that high (bottom is super hot and top ten feet are washed out), a big fish or mammal would come back bright yellow in that shallow. However, in the bottom left of the shot, there looks like there was a good little wad of fish on the bottom. Could be some corvina, mackerel or small bass or something along those lines. |

My Dragonfly 7 pro is getting a soft install Friday and I'm so stoked. I'll be taking it out for a quick paddle on Sat for a final adjustment before final hard install with in-hull wiring and plastics painting.
I can't wait!!! ![]() |

Great info thanks. This is near the pipe in carlsbad. Your comment regarding the "big worm" in photo 4 is to soft to be a fish. That confuses me because this is what I would expect to see if there is a larger fish under the kayak. So you said that if it was a bigger fish in water that shallow that I would see bright yellow color in the mark? Also, Is there a way to understand a mark being on the left or right side of the kayak? Or where you should be casting when marks show up?

You really can't tell which side of you the fish is on for the most part. I should note that its not impossible to tell, but its a very advanced technique without sidescan. The technique must be done with dual frequency, and requires a sideways oriented drift. The two sonar cones are not identical, and you can infer information from the overlap of the two signals. So if you drifted directly over an object (assume it's stationary) it would show up on 83 kHz first, then it would show up identically hard on both frequencies, then disappear from 200 and only be on 83 again. At this point you would know the object was on the upwind side as you drifted directly over it. If you practice this technique often, you can start to predict when the object will take this path. So once you just barely start to get the return on 200kHz, you can infer that it is down-drift from you. Anyone follow that? You can also slowly zigzag across an area and make similar inferences. Like I said, it's an advanced technique and takes 100's of "sonar hours" to be effective. I had an idea for an invention which would have a dual spectrum return that could differentiate between port and starboard orientation. Anyone know an acoustic engineer? |

Photo 1, I would agree with. Photo 2, could be a YT, WSB or even a Sea Lion. I would go with what I caught or saw. Photo 3, I would not guess Halibut unless you have your colorline very high. They are a demersal fish with no swim bladder and generally don't mark in hard colors (like many sharks and rays). I would guess YT or WSB. Photo 4, By the thickness of the mark at that depth I would lean towards YT, but it could be a WSB. Photo 5, By the depth and thickness of marks I would guess good sized Macks, Bonito or small YT. Quote:
Photo 2, The mark on the bottom appears to be a large fish, but I would bet it is a tightly grouped school of smaller fish. The broken edges of the mark over the entire length indicate that. Quote:
Photo 2, You are on the wrong frequency and over gained in that depth of water. Photo 3, Mixed species school of bait, or could be some smaller predators among them. Photo 4, That mark looks like a fish to me. I would guess that it is either a fish with no swim bladder or it is staying just outside of your transducer cone angle, or both. Perfect example of cone angle. The arches that are Red and solid are moving directly through the cone angle. The ones that remain blue and broken are outside the cone angle. The thickness of the bars, in the cone, are just the right size for the depth of water to match YT. I can show you hours of video footage on fish not biting. Almost all of it can be attributed to a sluggish or oddly moving bait. |

I agree on #3, i happened to get a halibut at the time, however there were lots of YT around as well so you could be correct. #2, Looks very much like a dog. But I got crushed by a 30# yt on that mark. I actually got the gopro footage of the mark, as it was diving then the bite on video. Edit will be coming... ![]() #4, could be yellow but a little "wormy" for me. This was on a day when all three slam species were around. #5 agree... could be boney. But a nearby friend caught yt right after so that was the basis of my assumption. And you are correct about them being smaller grade... 15-20#s. Greg makes a great point here. The only time you know for sure what the mark was, is when you catch off the mark. The first time you do this, and watch the fish hit your bait, you will gain a profound sense of accomplishment and confidence! |

PREFACE: no disrespect intended SteveOOO. Thanks for posting! Purely my opinion and I could be completely full of it...
To me, these marks don't look like fish. Not sure that I know exactly where this is, but looks to me to be an outside rocky kelp ledge area. Bull kelp zone. Note the symmetry and length of the marks. See how they are vertically stacked and all similar length, thickness, and heat. I see how both the "head" and the "tail" of the marks are all very similar, and taper off to a pointy tip, without much change in depth. To me this is indicative of stationary objects, or something that is drifting passively in the current. Yellowtail seldom sit still, and are usually very erratic looking and asymmetrical. The marks will look all "tangled" as the fish change depth and react to each other. This looks like a deep kelp ledge with a good amount of current, and bait in the bull kelp pinned down to the bottom. No doubt prime YT feeding grounds and epic conditions. Cheers boys! ![]() ![]() ![]() ![]() |

That was LJ, out in the sandy squid grounds. We caught yoyo YT off it.
One sonar setting that is worth putting into the discussion is Sonar Scroll Speed. It doesn’t change what you see on the meter, but it does change how it appears on the meter. I find setting a faster scroll speed will give me more of a real time picture of what is under the boat. It also gives more defined, and longer individual fish arches. Our kayaks move relatively slow, and sometimes we are chasing fish that move relatively fast (YT). I think of the slower scroll speed as the history channel, or “old news”, where sometimes what is shown on the meter is long gone, but it just hasn’t left the screen yet. The best time to experiment with this setting is when making bait. With the new chirp units, adjusting scroll speed to a higher setting can make a bait ball go from looking like a cloud, to showing hundreds of individual tiny arches. IMO thats too much clutter for just making bait, but turning up the scroll speed also does the same for a school of YT, turning that mess of squiggly spaghetti hanging out under the kayak into more defined individual fish. Fast scroll speed is my preference when yoyo fishing. When its there, its there. When dropper loop fishing or fishing for structure oriented fish, I’ll turn scroll speed back to normal, so I don’t blink and miss anything or leave an area prematurely. Normal or slower scroll speed is also good for giving a little more history of what the fish is doing under the kayak, e.g. showing a YT dive bombing your bait. Its really a matter of preference of how you want the fish & screen to look. *disclaimer* I’ve caught many more fish through dumb luck than I have by using my sonar. Good thread ![]() |

Great thread idea Chris! I love how your naming your sonar marks too!
For the first two pictures I'd like to welcome everyone to the promised land. The third picture is a good example of how bait reacts to a school of yellowtail. Even if your not marking yt if you see bait behavingg this way you can tell if fosh are around. Lastly, the 4th pic shows a single yt swimming through a small school of red crab. Yes my settings suck! For yhe 4th pic. |
