I can swear I have posted this several times....oh well..here we go again...

BSB Hooked and coming up.

Black sea bass checking out my squid jig gangion, note the 7 green lines, they represent the 6 individual squid jigs and a sinker on the bottom.

Little bit of squid on the bottom. (represented by the green)

Heres an interesting shot, broadband, dsi, and sidescan side by side of a small school of baitfish at cabrillo.

Just so you know that, seeing what things look like in pictures is no substitute for being on your kayak and in the water and studying your FF. You will learn alot more being on the water putting the time in than to have me or someone else explaining it to you.

Hell, Tony can tell you what the baitfish had for dinner last night by the color of their fart bubbles with that contraption of his

Thanks for the pics!
Ok real dumb question here.. So I mounted the transducer on the ram mount on the side of my kayak (wet mount) and the image on my HDS is the straight below my kayak, right?
So if I see fish/bait fish on my screen that means the fish are Right below, correct?
Thanks again,

I have a customer that is running a Raymarine Dragonfly, it has split capability, the regular sonar screen is on top, and the dsi screen on the bottom, so you can see that, what looks like a bump on the ground appears to be on sonar, actually is a truck tire with some weeds growing around it...then a nice flat area all around that..."bump"...set the hook!

Oh, Thanks for sharing Tony, very cool screen shots...

Not really. Your screen is not showing you an image, but a whole bunch of slices of information over time. Each new vertical line drawn is what the FF picks up in the last interval. Tony's explanation of the BSB checking out his Squid jig might be confusing you. What you are really seeing is him sitting over his squid jig for a while then over a BSB. Also, while your transducer generally sends a cone shaped signal in one direction, it is not necessarily straight down. It can also encompass a much larger area than you might think.

Thanks for all of the great info. My fish finder came with my yak and is not the technological wonder that you guys use... but someday, when I can get one that doesn't cost more than my yak, I will put this info to work.

You may have...I don't open up all of your posts...

Fishfinders scroll from right to left. What you see on the very right is what is under the boat/kayak right now, what's to the left of that, is what was. Like greg said what your metering may or may not be directly under your kayak but just in the sonar cone, the object/s could be off to the left or right, forward or back. 200khz is narrow beam and 50khz is a wide beam, 200 is generally used for shallow water and 50 is used for deeper water.

Confused yet?

Thank you!

@Fulrac you have a structure scan? I have a PA and was thinking of getting a Structure scan but just dont know where to put the transducer for it, I already have the transducer in the mount underneath for my ff, does that mean i have to mount the transducer for Structure scan in the hull?

ful-rac · 04-19-2013, 11:27 AM

Yes I do have structure scan, if you mount it it should be on an arm over the side, about a foot or 2 down.

Deamon · 04-19-2013, 11:51 AM

Great info! If you're not moving/drifting and a fish remains under your transducer, you'll get the prolonged squiggly line...

If you are drifing along and/or the fish just passes through, you'll get the upside down V...
