Finally a very basic comprehensive explanation from a great teaching skilled angler. Thank you for the simple breakdown. Seriously!

[@scottankers6690]

This is the best explanation that I've seen.

[@terrymcguirk7863]

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 KZbin! Thanks again!

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

[@540fishing]

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

No, you need a cow to explain it like this for an Auburn fan to understand it..... Mooooo

[@tonyjones9057]

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?

[@nicholasmusikoyo7609]

You're such a good teacher, thank you.

[@alwaystinkering7710]

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.

[@Ripp1n]

Finally videos for the North. Being from WI Johnny, you should do more videos on northern lakes, WI and MN lakes would be awesome.

[@badatstuff3690]

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.

[@jimknowles5483]

So Johnny, of the three fish finders, which is the best at down imagining??

[@KG-xf9ew]

Great video and well explained. There are too many crappy videos out there. This was excellent.

[@bbboyz5521]

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!!

[@shogunn5065]

Incredible info! This is extremely helpful, but it still takes a trip to the water to really click in the brain. Thanks again

[@rowdybroomstick6394]

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.

[@prynceal6762]

Good idea but if your in a body of water that has current (predominantly in Florida) that trick will be inaccurate.

[@SandmannOZ]

Doesn't work in the ocean... currents, winds, etc... unless you have a long rope and a weight on your bouy.

[@JohnPunch-h3m]

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..

[@jimmymeatwhistle4988]

Very thorough explanation of down imaging. Thanks so much.

[@0shondre1]

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

[@HughButler-lb6zs]

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.

[@boomchang1]

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!!!!

[@christianrobertadzic9321]

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.

[@kymora6203]

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.

[@philliphatcher548]

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.

[@Brandywine-farm]

[@intexxi]

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?

[@felixsupreme22]

I have this question as well. Did you get an answer?

[@billtiritilli5271]

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.

[@gwo8th211]

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.

[@mahaze55]

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

Could you use a down imaging transducer for forward facing sonar on trolling motor

[@small-town-southern-man3573]

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 ?

[@jakeMTSU]

bait ball or cloud cover/reflection can do the same.

[@bobnero19]

Outstanding treatment of this subject

[@brianharrington5593]

How close do you run the distance on your mapping? 20'. 50' 100' 200' 500' as this will make a difference on exactly where your WP is set to go back over and relocate the brush pile.

[@kenestra123]

Dumb newby question here, so once I see fish on my graph I would want to throw out a lure to the front of the boat or anywhere around it? My buddy said he can see his crankbait enter the water when he cast it out and let it drop down to the level to where the fish are suspended.

[@jakeroberts7302]

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

[@WeedsePoentah]

So the sonar only looks to the center down or backwards then?

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?

[@alexkoski5158]

Can you use a fish finder for anchor boat fishing?

[@rudylallave4370]

How far can a transducer effectively take pictures at the bottom when not moving? From back to front and both sides, and how deep it can penetrate?

[@WhataBurgerrr_]

Ok I have a question though not concerning the bruh piles but currently I’m at 6:02 in the video so what I’m wondering what is all the stuff suspended in the water and the same goes for the side imaging I’ll constantly being seeing a bunch of stuff in the black area and im just not entirely sure what it is at all

[@daviddincler7494]

Can you use depth shading when your lake is below pool lake is 723 at pool and now it is -18ft don’t have the or can’t adjust lake level

[@brianswiger3374]

Just the video I needed. Thanks a million!

[@nickseguine393]

is there anyway to set the transducer to start taking pictures more to the right to see the image sooner?

[@twotoned2774]

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.

[@nickseguine393]

@@twotoned2774 yes thanks

[@jamieshay4995]

Do you think di would pick up an image of a boat motor laying on bottom of the lake at about 20 ft??some people lost a 15hp 4 stroke Johnson

[@MikaelWende]

Such a great presentation!

[@SandmannOZ]

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.

[@davelerner8461]

Thanks Johnny, that really makes sense and you presented it very clearly, great video!

[@danham3344]

Super cool video Jonny!

[@jgalicic]

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.

I thought the imaging transducers projected a cone rather than a straight line?

Johnny. Great video! Got a ? On 360. Does the depth under the boat subtract away from the range like you said on side imaging? If I have my 360 on 80’ but I’m sitting over 20’ of water Is my target range then 60’? Just trying to tell how far away my targets are more precisely. Thx James

[@emilianobanzi9432]

Great job Jonny!

[@sonnyfulkerson3824]

Thx - very informative. A bit of a beginner question. When graphing do you troll or use main engine - does the wake from props distort ? What’s best method for this ? Thx in advance

[@clashcontent5407]

I’m not really an expert but for me on my boat it seems that whenever I use my main engine and I take it above idle the finder is usually distorted so I find it best to either slowly drift without either motor or just use your trolling motor and the graph will not be distorted.

[@kidiraq8381]

You transducer is probably not installed right if your getting distortion while graphing. Other graphs pinging can cause interference as well. So turn others ping off while graphing or switch to maps on the one your not using for side/down imaging. Graphing is meant to be done with the main motor but can be done anyway. Graph at 3-5mph and for best picture, make sure your "chart speed" matches your boat speed. God Bless!

[@outdooraussie6355]

Fantastic mate. Thanks. Cheers 🍻

[@markstebelton5953]

My transducer is angeled down under my boat. The beam is hitting the bottom nearly straight down from where I sit when driving and viewing my screen.

[@jerrysteiner9645]

If you anchor over a brush pile, why doesn't the finder keep reporting the bush pile image rather than moving it down the screen from right to left?

[@Jfldhr]

Can you a video for how to find fish in the fall in deep water?

[@scottbarker30]

How are the brush piles the same if the contour of the land is different and you went around the same point in the same direction? Not saying your wrong, just not sure I understand. 😅

[@jeremyboudreaux9313]

The odds of your boat going over the brush pile in the same exact path within inches or even feet is highly unlikely so the contour will be different if the brush pile is on the end of a point or hump if you pass over it even 2 or 3 feet away from where you passed it the first time

[@FishtheMoment]

Jeremy is spot on. I didn’t drive over the brushpile at the exact same angle and was probably 3-5ft left or right of my original line. This made the contour look different.

[@scottbarker30]

Thanks for the info and it makes sense now that it was explained to me Barney style. 😂

[@PCAPastorTrav]

This was super helpful. Would have loved the final step, how do I judge distance accurately when I go to use the waypoint from the mapping function?

When you elect the waypoint you want to go to on your graph, it will show you the distance the waypoint is from your boat’s transducer.

Could you throw a marker buoy as soon as you see the image? Probably no one does this. If you threw it slightly behind and out to either side as to not throw it right on top of the object you"re going to fish. I realize that's not very modern but it would also give you a visual as to where to cast.
