CHIRP Explained in 4 Minutes! Chirp Sonar EASILY UNDERSTOOD. 

I tried to make this video as simple as possible. Technically you can read pages and pages of what is really happening with CHIRP sonar. In this case, It’s technically a wide frequency range between 150khz and 250khz. (Not just 100 since they don’t come in nice neat 1khz chunks) I had such a hard time explaining the difference over the years that I found this gave guys a good “idea”. Instead of one, you get many. Thanks for watching!

i rarely comment on youtube, but man THANK YOU! been using a Lowerance hook4 for a year and it had me confused all this time. Played lots with the settings and it never was consistent. now thanks to your videos on here I finally understand! thank you again Mike!

Excellent tutorial. Please edit your audio with headphones. Your voice volume is considerably lower than the extra audio you add in Painful when wearing earphones.

Great video and appreciate the time you put into the flip chart explaining the frequencies and CHIRP! I'll tinker with my Helix 5 CHIRP G2 GPS some more but so far I think it is a POS. It was advertised/implied had DI and SI but after spending a day installing the transducer line and getting everything hooked up then into the water I found it does not have DI or SI which really sucks. Its too much trouble to take the boat back out, remove the transducer cabling and send it back. Humminbird bundles there manuals and specs together making it disillusioning as to which unit does what. So far the Helix 5 G2 GPS SUCKS

*I used it, I was amazed, **enjoyable.fishing** recommend The color screen really lights up. For such a small unit it is very easy to read.*

This is the best explanation of how the frequencies work on RU-vid mate well done. I'm going to give it a go and I might have a few questions if that's okay

Mike, you did a better explanation than the one I saw on (Kid Cochise?). It was your conical diagrams that did it. I might suggest that when you show chirp you draw multiple different color cones, each different color representing a different frequency covering different areas. Thanks for this though, Great video!

NIce job Mike. Need to get a mic! Keep up the good work.

Excellent again. Now I have a good idea of what folks are CHIRPing about.

Another way to explain frequency is the size of brush your using to paint a picture of what's under your boat. High Frequency small brush bounces off the first thing it sees, low frequency bigger brush bounces off the first thing it sees. Your cone diagram shows perfect example. but the display will only show 1 fish regardless to how many fish are in the cone.

In general, the TI units are faster in response to inputs. This is seen when quickly switching between sonar, downscan, chart, and split screens ru-vid.comUgkxeAxH15LxhjGlg5-CRYqjTGTEH0tbY4vk recommend The Hook units will show some lag on button pushes and screen switching. The big ticket item though is maps. If you install a mapping card such as Navionics or the free C-Map Genesis which has a lot of map detail, then moving around the map with the cursor or when running down the lake can lag significantly on the Hook units, but is seamless with the TI units.

Love these videos .So much more to sonar than the on/off button ..

Thank you for sharing your knowledge. Your video is very informative and has been a great help.

I'm new to this,...and I understood every word you said!

You are a artist. Bob Ross watch out

Seems like the one transducer needs adjusted. Regardless the chirp is better but the returns on the left could be improved by adjusting the transducer and also adjusting the settings on the head unit. Again chirp is still going to be better immage

Cool content and explained well. Looking forward to seeing you on the water.

These instructional videos are great! Thank you!

Yes , thanks for taking the time to do these videos, and me as well, learning a lot as we go, so thanks again....cept..the intro with earbuds bends my brain, way louder than vid volume, I cannot pull ear phones out fast enough, (sorry, that's my only complaint )

Great video Mike! Very good and simple explanation of CHIRP sonar. Thank you sir!

Wow this sonar vid has really helped me thanks !!

I have the TM165hw on my bass boat, love it!

Hey Mike, thanks for doing these videos. I really didn’t know too much about fish finders etc... enjoying the education.

This video is really good, thanks Mike!

Dude Sweet videos I really appreciate them appreciate you two love you mean it

I enjoyed watching you catch fish. The question remains, what is CHIRP.

Cone angle = 1/4 of frequency wave size in meters at distance of Time of flight : 2

Great info, thanks! You guys are having way too much fun......

Can't get any simpler than that. Great video

You have the LOW/MED/HIGH backwards, the cone is larger on the high and narrow on the low. Low is for deep water, high for shallower.

The comparison result on Simrad is normal. Furuno Rezbost and Simrad chirp wonder the result of comparison :)

Mike, getting ready to put the TM275LH-W with CP570 on my cousins 3100SXL Northriver and would love to pick your brain on settings. We are running Axiom 12’s front and back and do all kinds of fishing from shallower Salmon to deep water Halibut in 800 feet of water to albacore offshore trolling and live bait and jigging. Never have had a really consistant picture. Love my Lowrances for the ease of use.

Mike, I am very thankful for all these instructional videos. I have been watching your videos all winter and yesterday I took my boat out for the first time since ice out here in Indiana. I was able to set up my sonar much more efficiently and WOW I could see so much more. It was great to be able to actually see and understand what I was seeing especially on my side scan. Thank you brother!

Awesome video Mike, just one advice . On the beginning of you video where you show single frequency cones 200hz is wider than 83hz and much wider than 50hz.

Hi Mike! Nice vid like always! Very well explained 👌👌 Wich transducer are you running on the real chirp? I own an Airmar TM275LH and I'm really really happy. Before this one I had the totalscan 3 in 1. Like you, I think that the sides an is worth the money, but in traditional sonar, the airmar is thousand times better than the totalscan. Thanks for all the great videos! Waiting for the next one. Best regards from Spain bro

Great info and a good refresher........👍

Hey I’m a little confused about the come shape the shadow at the bottom is not round right it’s longer to the sides than forward and back

Dude thanks for the video but u need to adjust your volume offset between commentary and the cutaway NOISE

Thank you. Been strugling as a newbie with this. Great explanation

Great job explaining this!

Thanks for the info!

Watch videos on metal detecting and you'll fully understand. Minelab perfected this. Glad I bass fish and metal detect.

Hey Mike. Hope things are going well for you. When you look at transducers like the Active Imaging 3-n-1 now. Which probably wasn't available back when you first made this video. How do they compare to the dedicated Chirp transducers like you were mentioning in this video?

Why does Lowrance say they have CHIRP on all the Hook2 when in fact its not true CHIRP at least all the lower end units are not, yet there website say they are. very confusing.

Great vid Mike, Thanks

I’m on the BC coast and wondering how chirp will work. Was told that the P 66 was the best.

Great video 👍

Very good explanation of chirp. Your voice audio was extremely low had volume on high wearing head phones to hear you speak and then got blasted with whatever that was added to your video, I subscribed to your channel but highly request you either wear a microphone and review your videos wearing headphones to avoid your listeners getting blasted to the point it was a little painful. Thank You for taking the time to explain chirp sonar, just please correct the audio for your listeners.....

when offshore along a shoal, i was using high chirp and it was reading good for depths under 25ft or so, however once i crossed over the shoal the high chirp was not reading, unitl i switched to low chirp it read the shallow water under 20ft. I thought high chirp was for shallow water is this not correct all the time?

Awesome explanation. Thanks.

Your technical description of chirp is wrong. 150KHz to 250KHz is the range. Short of having the detailed operational description from the manufacturer (proprietary information), the transducer could be using anything from two to an infinite number of frequencies between 150KHz and 250KHZ. Saying that there are 100 frequencies is like saying there are only 12 measurements that can be performed with a 12-inch ruler. The reality is probably more like the transducer outputs pulses that sweep between 150KHz and 250KHz with every pulse being a slightly different frequency. Yes this is a better technology but it is not using 100 different frequencies. Understand that 150KHz is a different frequency than 150.1 or, 150.12 or 150.04. The spec of 150KHz to 250KHz is simply the range of frequency employed and how they employ that range is generally not made clear in an owner’s manual. Its probably anything from 5 different frequencies to 25 from one end of the range to the other.

That was a great explanation. One thing I can’t wrap my head around is it a cone or a 2D triangle?

Now I get it, Thank You!

Low: you will see 3 fish..Med: you will see 2 fish...high: you will see 1 fish. Easy enough to understand..

Thanks for that Info!

Well done! 👍🏻

What transducer are you using for high chirp on the right-side unit? You said the left unit was a P66. My understanding is the Tm 150 is for medium chirp. Is Medium or High chirp best for 40 ft or less? Low Chirp is the best for deep water, so high? Thanks

So what does chirp mean?

What setting is best for estuaries?, depth between 1m-7m.

As a beginner which frequency should I choose in a freshwater lake

nice video, thx for good explanation

beautiful video, I wanted to ask you for advice, as regards trolling snapper on seabeds that in my part range from 40 to 90 meters on which frequencies should I stay low, medium or high?

Mike, do you know what is the difference between B265LM and B265CLM? and we do a lot of bottom fishing, do you recommend the B265LM or B275LHW. btw i am using RAYMARINE PRO 9 RVX

Excellente video. Merci.

Does the cruise have skimmer transducer have chirp frequency

Thanks so much for the info! I use Garmon on my boat and recently went out to 1800’ of water and my units quit working in 600’. I want to be able to fish in those waters and fish in 70’ what in your opinion would be my best option? Thanks for your help.

ok one thing I cant understand: how the hell can you get the signature of your lures on the scope while obviously your lures are way behind your transducer, arent they?

where are you fishing in the ideo

You say 16-11 is high frequency, but my Tm185M makes the same cone angles and is medium frequency. Each manufacturer has its own criteria I guess.

Great video! Thanks for sharing. I bought a used boat with an Elite7 Ti with what appears to be the active imaging transduce with side scan. From previous comments, it seems that you are saying that this is "real" CHIRP. correct? I also have a Hook2 7 with the Triple Shot transducer and the unit lists CHIRP as an option...I think in the frequency tab. Is this "real" CHIRP or not?

Thanks!

Using the Go9 XSE, what is the best transducer you recommend? Thanks for the help!!!

Hi are You able to translate your settings and show what settings your using on the sounder eg auto , low , medium or how on the menus 😎thanks I liked the 4 minute video 😎😎😎

Super simple

Hey Mike awesome video thank you.. questions I have is I am upgrading to a garmin with the HD technology.. which transducer would we need for the chirp ? Most units including my current lowrance says it’s all in one and we do not need to purchase a separate one. If we chose to do so and upgrade performance,I cannot find a transducer thatspecifies it’s better for the chirp settings. Thanks for your time

Hi Mike thanks for all the amazing info. I am adding the active imaging to my transom. I currently have a thru-hull b-60 on my sportsman 207 masters would you leave the b-60 or do you recommend another thru-hull to compliment the active imaging 3-1? At the moment I bay fish mostly so 15-50 ft of water but plan on going a little offshore probably 50-200 ft. This is the first time I have had a boat rigged up with thru-hull to get sonar on plane how do you recommend getting use to marking fish going 15-20 knots?

How much energy do you need for the chirp signal only and could it be made solar or wind for a liferaft

Awesome Awesome Awesome

Can fish detect or feel chirp via the lateral line or swim bladder?

Thanks, could you explain what settings I would use to fish in 150' or more saltwater

Great now i have an idea what CHIRP is. thank you. i would have liked to see that on an actual instrument ..the differences i mean. Also that transition noise made me cringe .. a totally unpleasant sound..

How do I see all your fish finder videos, I like the way you teach..im new to them, and I have the lowrance 5x pr,and 4x dsi on dads old fishin boat I know nothing..

It should be the other way round. 50Khz for low frequency transducer = deep water, over 100yrds, narrow cone. 200KHZ transducer = shallow water, up to 100yrds, wide cone.

Each curved return is one fish?

Unfair though with the transducer on the left sonar being in an incorrect angle under the boat

Thanks for vid Why is the 50khz the widest cone?

So the marks your showing on the screen you never say is that structure or fish your marking

What about water depth?

Hallo Mike from Greece!!!! i use Airmar TM185 watching the very nice video i try to understand what happened to my transducer when i use a custom frequency lets say 90 khz and then changed to 125 khz i believe i send 1 frequency at the time?if so it works as a none chirp transducer as it uses only that one specific frequency at each time is pingig?how these 2 frequncies are related to the angle of the cone?since the the TM185 has 50 frequncies(85-135)and an angle of cone 11 to 16 deg.Thank you!!!

Nice

Now i understand this i can change my settings

Is not suppossed Chirp performs much better than single frequency? You didn't explain why single frequency performs better to you.

Is it hard to change a transducer?

chirp explained in 4 minutes... 12 minute video lol

Thanks for the info. But your intro is super loud then the voice not so much.

why does mine go from 55 to 200khz what cone size would i have?

Mike - What’s the best fish finder setup in the $600 range?

Hey buddy, thanks for confusing me even more than I was. I think you have your frequencies messed up in your video. You’re mistaking high with low. Low is for deep water and high is for shallow. You have it the other way around. The drawing you have with the cones are wrong. Low should be high frequency and vice verca.

Good thing I tig weld and thsts what welding arc looks like depends on kHz so it was easy to understand 😂

Did not watch the video, just came to comment, I found it funny, CHIRP explained in 4 minutes, and the video is 12 minutes long, Hahahahaha, just funny.
