Bro I’ve been a professional IT instructor for over 30 years. I can say, having taught hundreds of classes, that you are a fantastic instructor/presenter.
Excellent - I have a Helix 7 and have been confused about some of the issues you address. You did a great job without extra info I don't need, but want to dig deeper into Humminbird capabilities. Fish rivers as well as lakes in Western PA/Eastern Ohio and Erie. I will keep watching and move on to other videos. Thanks again!
Man I appreciate you and all the hard continuous work you put in for us knuckle heads trying to figure this out. Hands down you run the best channel on UA-cam! Thanks again!
I am a person that has felt I understood down image but I love to hear other Anglers points of view on how to use equipment rods and lures. Your videos are by far some of the most simplified yet spot on and informative videos on any platform
i am a complete novice and have watched a few vids in my quest to understand how these devices work and have to say that your's makes more sense than any others I've seen so far..thanks for helping it all make sense!!
That's the most clear explanation I've seen. Very well done! One thing I'll add. The relative movement of the fish and boat are key to understanding the image. If that fish decided to hang out in that spot, you would see a very long fish because the unit would keep seeing and plotting it. That's the only time when you can be pretty sure where the fish is: when the boat is not moving and there's a long streak, it's parked directly under the transducer. And just like circling with the boat, one fish might appear as many if it's swimming around under your stationary boat. You're seeing the same fish repeatedly. That's a good clue that it's interested in your bait.
By far the best explanation of down imaging I have seen. That explains why I find sonar more useful, because I am not getting the best image on my down imaging view. Since it is a series of pictures you must have the proper coordination between boat speed and scroll speed in order to get the best picture of what's below the boat. The question remains as to what the shape of the image field is. Sonar is a cone ( 3 dimensional). What about down imaging? In using a fish finder, you need to understand you are interpreting a 2 dimensional image on your screen in a 3 dimensional world. You have to have your mind right says the warden.
Great explanation. Try this. Match boat and gps speed. Use right angles. 30’ of depth @ 45 degrees = 30’ behind you. I used that until I heard you. Thanks.
FANTASTIC VIDEO!!! I just got my first fish finder and small boat this takes so much guess work out. This link to your video should come in the box of EVERY FISH FINDER!!!! FRUSTRATION ENDED!!!! THANKS AGAIN!!!!
You can also use a throwable buoy marker to check the accuracy of the graph. As soon as you're making your second pass with the boat and are lined up to drive over the brush pile. As soon as you begin to see the brush pile coming onto the screen throw the marker just behind the motor a few feet. I mark my brush piles and structure this way as I feel it's more accurate than scrolling the screen back and asking the GPS to do it. Just hit the waypoint button the instant you begin to see the brush or structure your wanting to save. I do this usually on my second pass to make sure I'm not off to one side or the other. Although sometimes it may take several passes to get the best centered picture on the screen before I hit waypoint save. The gps method can work for bigger piles or if I have more obvious features on land I use to get my boat situated.
Glad you said the area below and not the area around your boat my deeper fish finder has a icon that looks like a diameter in a circle so I thought that meant it was the area around so now I know it's just a width of the beam and not some diameter of a cylindrical cone.
Man thank you so much. just wish I had found you sooner....... Could you do a video of how to find bluegill beds with down imaging my finder is a Garmin vivid 5cv and I'm having a hard time finding the bluegill beds.. thank you sir..
Hi! I really love the way you instruct the whole video. A great explanation. Thank you for your time to share. I'm using a Helix 12 unit exclusively for object searching, not for fishing. On my unit I have the option to record to the SD card the sonar data and I can load it to an app on y PC. but the recording is recording 2D and down imaging data. Most of time when I'm watching in real time, I use SI. Now, I'm interested, what are the yellowish area under the "river bottom" line? I mean, the area between the river bottom line and the real bottom of the screen? Thank you for any explanation, or maybe you have a vid for my question too.
I think part of why it's confusing for many is because they don't really understand what they're looking at. The vertical scale IS a distance scale, but while the horizontal scale LOOKS like a distance scale it's not... it's a TIME scale, ie: what is under my boat now, what was under my boat five seconds ago, what was under my boat ten seconds ago, and so on. This is made more confusing because if you drive a straight line and a constant speed then the horizontal scale can be interpreted as a distance scale with the screen showing a "cross section" of the body of water, but relying on that to remain the case without accounting for variations in course and speed can lead to misinterpretation. Similarly your screen make show a bunch of fish across the horizontal, but if you're sitting still over a given point that could easily be the same one or two fish swimming around under your transducer repeatedly.
we used to sit over suspended deep fish and when they stayed under the boat which didnt always happen, it would echo streaks on the graph. We called it streaking. It was first done with a unit called a paper graph, maybe a Z15 or 16 model???? its been a while. I still like to DI with vertical fishing baits, I can get so entranced in it that you forget about the trolling motor and fishing line thing. The staring at screens all day didnt start with livescope by the way.
9:07 it can be described as a path alignment that creates an active profile. Your advice is to keep in mind any changes in your path. Of course, a linear path will be easier to read. Thanks for the tutorial. Cool stuff.
Question, once you create your waypoint am I correct in thinking that providing where your gps puck is on the boat, (mine is at the rear of the boat) using the casting ring feature and the length of the boat, mine is 18 feet long. setting the casting ring to 70 feet will put the brush pile roughly 50 away in front of the boat? Also my trolling motor is linked to the Humminbird
Great lesson Jonny ,, A marker would help explain also. I'll use this video next time I go out, I know these videos have to take a lot of effort. Much appritated !!
Great info Jonny ! On my Simrad GO5 touch screen unit it will tell you how far away from an object that you marked on the graph until you clear the cursor. On my Helix 9 if you put the cursor on an object it will tell you how far away you from the object. If you have a trolling motor linked to your graph you can easily go back to the waypoint or cursor position that you marked.
Just picked up a Nitro bass boat looking to update the electronics on a budget along with the trolling motor. Ultrex is my choice for motor but like to pair it up with something hummingbird suggestions.
How wide is the area under the boat being scanned? For example. If one of those brush piles was 10feet to the left of the boat and you didn’t drive directly over it, would it appear differently on the screen? Or would it not appear at all?
I have a home fishing kayak and am using a portable Hummingbird unit. If I mount the transducer with the suction cup on the side of the boat and the flat end of the transducer is facing down instead of horizontally, what happens to the imaging? Will it still work?
I honestly doubt it because the xducer emits the signal straight down and it reflects back up. Before I knew any better I had my xducer positioned wrong and it never gave accurate reasons. It showed I was in 1ft of water then 14ft. It kept giving me bad readings. Hope that answers your question.

30 years deep and still says bro
@@YourDadsCawk that’s what I said

Finally a very basic comprehensive explanation from a great teaching skilled angler. Thank you for the simple breakdown. Seriously!
This is the best explanation that I've seen.

Breaking it down so much that even an Auburn fan can understand it

I resemble that remark
You spelling Oklahoma wrong
No, you need a cow to explain it like this for an Auburn fan to understand it.....
Mooooo
i am a complete novice and have watched a few vids in my quest to understand how these devices work and have to say that your's makes more sense than any others I've seen so far..thanks for helping it all make sense!!
By far the best explanation video for this topic. All the others I watched the person explaining assumed too much about how much I already knew.

Never used a finder, and step dad just bought a new boat that came with one. This will help us learn so much! Thank you!
Finally videos for the North. Being from WI Johnny, you should do more videos on northern lakes, WI and MN lakes would be awesome.
Amazing tutorial! I already knew most of the information but still great to see it how you explained it!
Great video and well explained. There are too many crappy videos out there. This was excellent.
As usual, you did a top notch job explaining Down Imaging. I have that on my Garmin and I never use it, I will now. Thanks.
This is one of the best explanations I have found. I am brand new to fish finders, thank you very much you now have a new subscriber.
Excellent demo. Thanks for this really clearly stated simple overview of down imaging. cheers

I do salmon fishing with my Dad on west coast Canada. This has helped me a lot solidify my understanding. Your video is greatly appreciated!
Incredible info! This is extremely helpful, but it still takes a trip to the water to really click in the brain. Thanks again
Very thorough explanation of down imaging. Thanks so much.
I needed to see this because I buy stuff for the boat just because lol so thanks now I have a better understanding of how to use these fish finders
This was the best explanation on how Down Imaging I've seen!!👊🏻Great job Johnny!!!💪🏻 Stay Safe & God Bless!!!
Best Explanation yet!

Always learn something new from this channel
Outstanding treatment of this subject
So in general, when you locate a brush pile or some structure you wish to fish, you have to circle back to fish on that spot?
You can also use a throwable buoy marker to check the accuracy of the graph. As soon as you're making your second pass with the boat and are lined up to drive over the brush pile. As soon as you begin to see the brush pile coming onto the screen throw the marker just behind the motor a few feet. I mark my brush piles and structure this way as I feel it's more accurate than scrolling the screen back and asking the GPS to do it. Just hit the waypoint button the instant you begin to see the brush or structure your wanting to save. I do this usually on my second pass to make sure I'm not off to one side or the other. Although sometimes it may take several passes to get the best centered picture on the screen before I hit waypoint save. The gps method can work for bigger piles or if I have more obvious features on land I use to get my boat situated.
Good idea but if your in a body of water that has current (predominantly in Florida) that trick will be inaccurate.
Doesn't work in the ocean... currents, winds, etc... unless you have a long rope and a weight on your bouy.
thank you sooo much. I bought one of these and I was so confused about all of it.
Glad you said the area below and not the area around your boat my deeper fish finder has a icon that looks like a diameter in a circle so I thought that meant it was the area around so now I know it's just a width of the beam and not some diameter of a cylindrical cone.
Thanks a lot , as a guy who has not even been in the water yet that was great. Thanks for sharing RayK. UK. YNWA.
Very helpful! Thank you on behalf of us new to reading fish finders!
Such a great presentation!
So Johnny, of the three fish finders, which is the best at down imagining??
Subscribed to bass fishing declassified
Excellent video Jonny. Thanks!
Another great video! Thanks FTM
🔥video
My son and I are learning together
New to this stuff
Valuable content plus I subscribe to the new channel I’m in ND
Just the video I needed. Thanks a million!
Good simple explanation
Super cool video Jonny!
This made is so easy to understand thank you
Thank you for making this video it was extremely helpful
Awesome video
Thanks I have a clear understanding now
GREAT VIDEO TO WATCH THANKS,
Great format for helping people understand. Thanks heaps.
Great job Jonny!
This is a good video. Thanks for explaining this. It makes sense now 😊

We need more of these basic sonar videos Johnny! Thank you young man

I gotta read these for some big cats or pay a guide put me on them but yes get this for my boat

Thank you for this! Much needed explanations for me here!
How wide is the area under the boat being scanned? For example. If one of those brush piles was 10feet to the left of the boat and you didn’t drive directly over it, would it appear differently on the screen? Or would it not appear at all?
I have this question as well. Did you get an answer?
Great video! Question: While you’re doing the slow-mo around the three minute mark, what is the large yellow blob suspended in the water ?
bait ball or cloud cover/reflection can do the same.
All you need to know is that *the current boat position is always on the right hand side of the screen.*
FtM: heres how to use down imaging
Randy Blaukat: down imaging sucks and heres why!!
Thanks so much
Helix high frequency along with chirp has increased the resolution to such a high degree
Dial in Chart speed and boat speed
Yes Johnny hello. Question. Why do I lose all my a-rigs on the same wp? I don't like brush, its expensive to fish there
So the sonar only looks to the center down or backwards then?
Could you use a down imaging transducer for forward facing sonar on trolling motor
Helpful. Thank You
I have a home fishing kayak and am using a portable Hummingbird unit. If I mount the transducer with the suction cup on the side of the boat and the flat end of the transducer is facing down instead of horizontally, what happens to the imaging? Will it still work?
great content! I'll come back to this comment if I can a fish using what I learned here about down image.
is there anyway to set the transducer to start taking pictures more to the right to see the image sooner?
I honestly doubt it because the xducer emits the signal straight down and it reflects back up. Before I knew any better I had my xducer positioned wrong and it never gave accurate reasons. It showed I was in 1ft of water then 14ft. It kept giving me bad readings. Hope that answers your question.
@@twotoned2774 yes thanks

you should check out some of Tom Boleys Walleye Snap jigging videos. Amazing jigging right under the transducer. Mind blowing stuff
