Kayak Sonar Discussion

Hey Gang,

I feel like a lot of people have the same kinds of questions when it comes to sonar... Especially from those folks who have just recently got their first fish finder, or have upgraded or switched brands. In internet forums, you typically want to avoid having a bunch of different threads about the same topic. It makes it hard for people to go back and search for the info they need.

Some of you who have followed me for a while know that I like to offer sonar tips to fellow kayakers when I can. So I thought I would start my own sonar thread, and try to make it more of a centralized location for some of this info.

The format I envision is that people can ask some of their sonar questions here. I'll do my best to check in often, and answer the best I can. Other more experienced members should chime in and address whatever they want, or tear my theories to shreds if you want... I can take it don't worry (;

What the thread is NOT for: Put-downs or trolling others, arguing with others about which brand or product is better than another, online deals or people trying to sell their stuff. I use Lowrance, but I will not try to sell their stuff or try to convince you that it is better than another product. This should be the place for technical discussion and sonar theory.

I'll kick it off with a few sonar tips for beginners, and a few screen shots from my IG archives


1. Try to mount the transducer in the water. Yes, shooting through the hull works, especially if installed by experts like the guys at OEX. I've done it both ways with the same FF and trust me you are losing sensitivity and signal strength. I would go with a RAM boom arm over a through-hull install every time.

2. Use separate power supply for FF and bait tank. This is for obvious reasons, if one system goes down you don't lose the other device. An entry level sonar like an Elite 4x for example uses very little amperage without GPS. The pump will drain batteries fast, especially 12V. Learn how much juice you need for your setup, and size your batteries appropriately.

3. Stuff will corrode, and need to be repaired. Next time you're at OEX or west marine, buy a bunch of extra terminal connectors, heat shrink butt connectors, and wire. Have all that stuff with you at the launch so when your sonar doesn't turn on, you can repair it right then. Make your wiring easily accessible and give yourself extra slack in case you have to cut and reconnect.

Now the "plotter porn"

Great info. Thanks. I'm still a noob when it comes to reading an FF.

Feel free to ask whatever you want. Even if you feel like a noob, I'm sure many others have the same questions and will appreciate you asking.

Can someone say sticky...

Chris,

First off, thanks. This type of input and support has made this forum a wealth of knowledge for many.

I can't speak for others, but I have no problem saying that using a fish finder has been one of the more challenging aspects in my fishing, as I spent my entire life fishing without one, until the last couple years.

I know many may like to know more info about this question:

"So I've gotten a ff and hooked it up, now how do I optimize the settings for fishing Inshore Saltwater?"

Cheers,

Todd

What is the difference on FF and sonar?
Or why do we need the two of them.

60' or less: you can play around with all different frequencies and see all kinds of cool structure and fish. low frequencies, you will see tons of huge boomerangs, and get a lot of non-sense returns of grass and smelt and ribbon kelp and all kinds of noise and weird stuff. use 200 kHz plus for shallow waters, and use downscan if you have it.

~60' deep or more: you want to be using your lowest frequency mainly. if you have a big enough screen, you can run dual frequency on one screen. But still the lower kHz the better. If you are just getting started, use only your low frequency. lower kHz has better penetration of depth, and seeing beneath hard marks like macks or crabs. it also typically will have a wider beam, which means you can see out to the side around you more. higher frequencies see better resolution of smaller or softer objects. so if you want to look at individual greenbacks, higher kHz is better. Low frequencies will give you the boomerangs and worms of big fish. turn up your sensitivity or gain until the bottom looks like a very "hot" or "hard" color (ie, the bottom looks like my pics above, in whatever color spectum you have)

Oh yea, did I mention that having color is pretty important?

EDIT: I should also add that you want to use the highest ping speed possible for fishing the deeper waters of LJ and inshore socal.

If you get that far, then take some screen shots and post them here. I will give you some feedback from there.

FF is a type of sonar. I use the two words interchangeably so as not to be so repetitive. I will also call it a "meter" or "sounder" sometimes... but its all the same essentially.

Tagging along to read. I previously had my transducer installed through hull with goop until I used my brother's yak w/FF (in water). The difference in clarity was AMAZING so I immediately changed mine. I haven't gotten to try it yet but excited to check out the difference.

Thanks for the opening this sonar thread.
I am still figuring out my HDS gen3. and looking for more hints.
What is the model of your FF and what kind of transducer do you have?
Is there any other settings that you recommend beside low frequency for 200'/300' of water to find the structure?

I have the Elite 7ti. Transducer is 83/200/455/800, not the total scan. If you are fishing deep structure over 200'+, you have to be using 83 or 50 kHz, or MID/LOW chirp. To see the bottom well you should turn up the gain. Then the top half of the water column will be "washed out" and have a bunch of feedback and noise.Either turn up the noise rejection and surface clarity, or zoom in on the bottom using the + and - keys. See how that works for you.

You never ask me questions! Relying on me to interpret my FF all the time. Sheesh!

Can you see fish in REALLY thick kelp the extends from the bottom to surface?

I normally have to adjust the sensitivity to where it almost shows nothing in thick kelp. Then I am not sure if I see fist or not. Lol

Yes for sure you can. Sometimes the key with that is the color line. Play around with colorline until you get the kelp to mark really soft, then the fish or bait will stand out more. I also like downscan 455 kHz for this application, because you can see the individual kelp strands and a fish really sticks out.

If you can get the DS dialed in, then you can overlay it on top of your mid/high chirp... for a more advanced configuration.

Definitely gratuitous sonar shots are welcome

Just be careful giving out your coordinates!

Thanks for the thread. I have a few images I would like to share and get your opinion on what you see. I didn't catch any fish during these meter reads.

That's a tough question without a bunch of other info... but I'm going to assume you mean for targeting yt in LJ or similar area. Also assuming your transducer is mounted in the water.

Splitscreen mid/hi chirp, ping on fastest setting, auto bottom lock on, sensitivity auto +1 or 2, colorline about 60%, scroll speed 2x, clarity and noise filters +1.

Start there, take a picture, post it here. Cheers!

This thread is awesome! I always wasn't sure what I was looking at..I kind of figured out baitball but still not 100%
I have HDS gen2 with 50/200 transducer and I can't really get tuned in..
Any suggestions?
Thank you!
