Thank you, young man, for helping an old guy understand this side imaging. These electronics are not as natural and easy for us to understand. You are a gifted fisherman and teacher.
Good video but a couple points to clarify. The center dark part is actually not just straight down, but a narrow cone (same as down imaging) which is why sometimes you will see items in the right dark area that aren't in the left part or at least not as bright in the left part. Second point is the side imaging doesn't ping straight to bottom and then shoot the right and left. It just aims the sensor at an angle, so it shoots from the transducer beam at a wide angle that ends up touching the entire bottom from below your boat to whatever range is specified. There is no technology that allows you to change the direction of sound waves once they leave the transducer. Also, even if they could shoot down and then to right, you wouldn't want that because you'd miss everything above the bottom to the left and right of the boat.
Actually; he is correct in a technical sense (Geometry and Science), Sound waves will hit and return from the closest point first, but due to the speed of the sound wave it makes no difference, as the screen will display it as it's algorithm is programed to interpret the returned signal. What does make a difference is in understanding what the image is representing with respect to the boats location, and he did a good job of illustrating the point.
Exactly. So his distance explanations are incorrect. Fishfinder doesn't measure surface distance to the object, but it measures the actual distance to the object (despite the depth).
Nice explanation. I just wanted to point out that the beam doesn't go to the bottom, and then kick out to the side. Sound waves don't move that way. It's actually using more than one beam, and combining the results.
I now understand more in your 15 minute video than I learned reading every article i could find in the past 5 days. Thank you for explaining this in the detail you did.
This guy deserves an oscar...can't believe he wud go through this much trouble just to show us how this hi-tech stuff works...thank u sir for showing us what the manufacturer doesn't care if we know or not long as they get our money....u should get 15% of every penny they make.
Sir, you are a natural teacher and this video has taught me more than any other I've watched. I am saving it and going to re watch it just in case I missed something.
I have a complete Humminbird setup with three Helix units, Ultrex, and 360 Imaging and while I agree that Johnny did a superb job explaining all this (I did have a one-on-one Google Hangout session with him), I have to say that Humminbird has a loooong list of videos on various topics. I'm not sure about the others, but thought I should mention this out of fairness to HB. They also have phenomenal support.
Don’t tell them that... cause if they start making their own vids... they’ll charge more for products. Besides... I like watching this guys videos! Awesome job, sir! Did well explaining what I needed to learn!
I hope you get paid by one of the manufacturers to do these videos. Either now or in the future. Your clear, concise and show real examples that help us all enjoy fishing more
I have to say I am an avid fisherman and spend hours watching fishing RU-vid videos, you do the best job at teaching and making some complicated information easy to understand! You have a very bright future keep up the good work I love your videos!!
This is a fantastic explanation and illustration, exactly what I needed! This explains why my side imagining wasn't picking up known structure very well to the side while salmon fishing in 120 feet of water when my SI setting was at 100' left and right. I never knew that. Glad I watched this.
I’ve been using Lowrance electronics for years now. I thought I completely understood side imaging. But I have to say that in all my years I never picked up on the fact that you have to subtract the depth of the water column from the distance that you have the side imaging going out on the side. Head slap! Thanks so much and I’m a subscriber for life!
You still have total range, just the nadir region or water column will grow/shrink based on depth or altitude of transducer relative to the bottom. A easier understanding is to basically say that the first return (colored area) range is going to be equal to the water depth or altitude of the transducer relative to the bottom. With that said, the object of interest is still going to be the actual distance shown on the display. People also need to keep in mind when taking or marking waypoints/locating objects by waypoint or coordinate, the actual position is skewed if using the internal GPS due to the offset/lever-arm of the transducer to the GPS sensor. This is why I like to have an external puck mounted near the transducer. Great video! 👍
I am about to purchase my first side imaging fish finder. This video definitely is a must watch for anyone who is in the market for one. The manufacturers websites are full of useless information with specs and numbers. No user guide or anything actually helpful. I was very apprehensive about getting one due to the myriad of mixed reviews for all of them online. So many 1 star and 5 star reviews. I think it is just misunderstanding the equipment now that causes the poor feedback. Now I can't wait to get the new finder. Great video.
You have so much information in your brain it is unbelievable. There's a big difference between you and me. I LOVE to fish...You LOVE to fish and KNOW how to do it!! Great Job!
Man Nobody does it thorough and as Splendidly Perfect like you....Period! You are a GOD-send amonst men good sir and THANK YOU for ALL you do for the Angling and good kind human being Community!
You have cut my learning curve down so much. Always been a shore-beater. But with these videos I'll be setting up offshore and gaining confidence in my overall ability. Other youtubers give info but don't teach. You understand that info is nothing without practical application. Your approach is by FAR the best I've seen. Thanks!
Wow, You are the first person to explain the distance right or left =depth plus range right or left. I could not understand why I was getting mirror images on right and left at the edge of the black center. I thought side imaging just could not see straight down. You make perfect sense. Ooooooo there's going to be a better brain in my boat. You just took the gap out of my image. I have been working on some giant crappie in a lake I have only fished a few times. Truly big crappie. Over three pounds. I lost a four-ish pounder at the net yesterday. I keep trying to locate the school with the side imaging but I am only actually finding them when I use the down imaging. That black strip down the center was throwing me off by exactly the water depth. I have been catching some, but the school I have been seeing on the side imaging was 21 feet away from where I was casting! ( 21 feet deep) This information is fantastic. Now I can make sense of the missing structure and fish I have been chasing between side scan and down imaging. Thank you so very much. Smiling, George.
Anyone else think this young man is an excellent teacher? Never loose your enthusiasm Fish The Moment! :-) Great job and Thank You! Keep up the great work!
This is the explanation I’ve been looking for. Everyone else want to show you the features and don’t explain how to read them in real time. As a newby to using a Lowrance, I thank you!
Very good explanation. After 2 years of using my Humminbird I didn't know the details of side imaging. I'm glad you continued "beating the dead horse" I needed the repetiton. Thank you!
This Incredible,your giving me information I've never understood before,I've already saved this and all your videos to my favorites, I'm kinda upset that companies don't explain "FINE DETAILS " like this to help fisherman to understand COMPLETELY what were looking at, thank you Jonny 👊👊👍
Think of it this way: The manufactures aren't in the business of education. It is the same with Chevrolet - they don't teach the buyer of a new truck how to operate ALL those features from one bumper to the other.
You really should have gotten a reward for this video.... It is so mis understood to guys with sidescan and structurescan .... that the range feet left and right are not considering the down depth. Great job.... 3 years later but still i go to this twice a year
Thanks for making this video. I sent it out to all the guys who bought units and didnt like them because they didnt fully understand them. This helped a lot.
I just found your channel by chance….LUCKY FOR ME!! Great vid brother. Very well described. I was about to purchase my first unit, and now I am informed. Thank you, my brother.
FINALLY! A video that concisely and in non-technical language, explains the side-scan sonar! I’d love to see one of actual fish... Seriously, the more of your videos I watch, the more I learn. Great job- you’ve got a natural talent for teaching and relating this information! This new subscriber is “hooked”!!!
Yeah I agree with the last writer who proclaims to be of the old buzzards club, of which I am chief and I teach as well. Your a great teacher and it helps for you to say something three times. It get the point across. You are helping me well. Thank you.
If you are right this is the best video i have ever seen about how this works. I feel you know what you are talking about so i want to say thank you very much. Great job
I cannot give you enough kudos for this video. You have a rare ability to make your subject understanable through your common sense examples. You are the best teacher I have seen after watching many videos. One from a factory representative who was clear as mud!
Excellent. Reiterating points over and over is what old guys like me need. No shame in that as its uber helpful. Getting excited about trying my 3 year old fish finder out for real for the 1st time!
Just got my first boat and learning to understand what the Garmin Striker 7 is showing is by far the hardest part but you just made it a whole lot easier! Thank you!
This is a very well put together video. Better than the videos put out by lowrance. It was helpful. My son and wife got me a lowrance HDS9 and it can be somewhat confusing. Thank you very much for this. I sincerely appreciate it. Don
Searched for exactly this type of content when I bought my side imaging a few months ago and there was nothing out there. Thanks for your passion and clarity. Keep it up!
As old as this video is, I just got a garmin echomap uhd 94sv, and this will effectively be my first sidescanning/chart plotting fishginder. This video just taught me a LOT
Thanks again for doing this video. I watched both tis one and the Jan 6, 2018 one today. I'm fairly new to using the SideScan and DownScan and you cleared up a ton of questions for me. Especially the part about the Water Column on the SideScan. It all makes since now. I'm looking forward to getting on the water once Montana Winter is finished.
Thank you for a simple visual explanation for what is a very abstract thing in my mind. I have asked many people to explain what I am looking at on a fish finder and have gotten wrong or little explanation. I look forward to learning more.
So very explanatory!! I was not aware that the water depth was part of the right/left distance. Learn something new every time I watch Johnny!! Thanks Man
Great explanation! I have debated with so many on this and they think if their graph is set to 60 feet on each side, it is scanning 60 feet left and right but they don't understand that the depth of the water is also included in that and they aren't subtracting the depth of the water. I hope many others come across this video to better understand how this works!
Fish the moment.....you have one of the best sonar explanation YT channels out there! So thank you for this and showing all this stuff to us. Really appreciate it!
Thank you for confirming what I thought about side distance. Most people just look at an object, compare to the scale, and say that's the distance, without taking into consideration the water depth that needs to be subtracted.
Thank you, I have had my side imaging hummingbird for over a year now and never could understand it. Now I will be going out and trying it this week with some much valuable information. As Steven said earlier, it does not come as easy to us older guys. Thanks Again
Seriously great information. I have all new electronics going in my center console this year for inshore/offshore fishing. A pair of garmin xsv’s and a gt56. I’ve watched so many videos and yours is the first that I’ve seen that clearly explains how the depth and width are configured. 80 foot setting don’t mean 80 feet to the side. Thanks again. Learned something new today. 👍🏼
Awesome video Johnny. Definitely helped me. I’ve always had trouble understanding side imagining. Looking forward to seeing what fish look like on side imagining. Keep those electronic videos coming.
Spot on man!!! This is probably the best in point video of how to understand side imaging. I'm impressed you did in less than 20 mins. As much as I like the tactical bassin guys their interpretation on side imaging is way off. They should apologize to the community for misleading them, take down the vid and redo it correctly
Finally i freakn can understand this fishing electronic stuff. I bought a really expensive garmin unit with the live scope, I had it for about 6months+ now and always trying to figure this out till now. FN thank you. Please keep uploading these kind of vidz. Thank you so very much.👍🙏🤩🕺
I think I read you were studying for your Business Degree. I really feel your major strength is in teaching. Consider “Academia”. We need more educators like you. You totally clarify so many muddy subjects. Fabulous video...as usual. Also...headed to Ouachita April 1st. Any fishing tips????
Excellent video. Well done. I appreciate the fact you teach realizing people like me don't know the basics and need to be spoon-fed. I agree that Lowrance, Garmin and the like should include this video with every unit sold. Thank you!!
I’ve had SI for several years and and I always suspected that you subtract water column from total range but no one until I saw this video had confirmed that. Thanks for confirming this for me.
I was beginning to think I wasted my money adding sidevu to my Garmin system because I had no idea how to use it. I can hardly wait to get out on the water again and apply what you’ve shown in this video. Thank you!
Great video. I didn't think about figuring in the depth down in with the distance out for my total length. We are having trouble setting sensitivity and contrast at different distances to look under docks. I would appreciate you touching on that in your next video if possible. I understand that is different for different lakes, but I would assume there is a go to setting that everyone starts with besides factory settings based on some of the videos I have watched on RU-vid so far.
Very good information very helpful as I just got a Garmin UHD 94sv with side imaging and your video gave me more confidence in using this feature. Thank You!
Very eloquent example of of explaining side angle sonar imaging. Appreciate that you realized that a single long video on this subject, albeit very informative, would have been too much overload. Nice job of editing your video to match your tutorial. You show some professional promise. I'll be keeping my eye on you and your upcoming topics. 😃
CrappiElite Outdoors neither does most of the hummingbird staff and I would guess the Garmin staff also. My buddy called hummingbird and he had to be transferred to a lead engineer because no one else could confirm what this video is stating. Turns out the video is absolutely correct.
Great instruction! I just ordered a new Lowrance Hook2 7 Tripleshot for my Kayak and am new to DS and SS but feel this has definitely helped get me started at understanding and having less frustration when I cant seem to cast on the fish. Thanks
Thank You! This is the best video out there! You are an excellent teacher! I WILL be watching more of your videos. Thanks again for sharing your knowledge on this subject.
