Calibration question

[dricha21]

I calibrated my 93sv when I first received my unit. I seen the little boat with the cone angle extended out from it on the forward view figuring this would help with figuring which direction my transducer was pointed. I found it to be incredibly inaccurate. Sometimes the cone will just rotate in circles around the boat while I am sitting still and other times it just doesn't come close to where it is pointed. AHRS is on LS is calibrated. Does everyone have this issue? Also do I have to calibrate every time I get to the water? I only had to do this once with my Humminbird so I figured I should only have to do this once on my Garmin. But every time I go out I have to calibrate if I want to see the Little boat symbol. Although I stopped calibrating because it is so inaccurate. Does calibrating help with any other features that I should do it at the start of each trip?

I never calibrate because of same probs you had. Where my trolling motor arrow is pointing works for me.
I heard you must re-calibrate for different lakes. Not sure tho
You definitely must recal after switching views each time.
Maybe stowing trolling motor up and down messes it up?
I turn AHRS off and manually select the view I want (always forward anyway)

Mine acted like yours so now I do not use that feature- I'd rather not see that damn icon on the screen and it is not required.

you can make the icon go off the screen by starting a calibration but cancel out of it.

I think for it to work correctly you need an auxiliary heading sensor on the boat as if it is using the head units gps to tell orientation compared to transducer, this is where it gets wild.

if everything is setup correctly you do not need to calibrate every day. Only when you go from forward/down to perspective modes, I would never bother with calibration unless you are trying to drop waypoints on livescope screen. I do not use garmin for mapping it is only a stand alone unit to me.

Yeah, I think you need a heading sensor. Mine was acting up the other day, doing what your describing. Figured out I forgot the turn power back on for the NMEA2000 network. I think I re-calibrated it 3 times before I figured it out, Lol. Must have looked funny to other fishermen as I was going in circles!

What do you mean forgot to turn the power back on? When you have the directional cone showing up like it is supposed to, is it accurate?

[Fishysam]

Without power to his heading sensor if the boat is drifting left 90* that is now what the unit thinks is forward, so the tm pointing straight will display the icon at 90* right, so this is how we get bogus readings

I am a bit confused. I do not have a heading sensor. Just the 93sv and the GLS 10. My LS transducer is mounted to a separate shaft. Does the boat have to be moving to give a accurate cone direction. I thought it could detect magnetic direction and that is what it gave the direction of cone from. I would like to see cone direction accurately because my setup is hard to see the direction the cone is pointed.

Maybe sitting on a ice hole where nothing is moving, I'm yet to see that icon function all day without a heading sensor, someone else may have more input but that's what I have seen over and over

your stick for the transducer, why not make a L handle for it and align it with the transducer. This would be easy to know direction then.

I have transducer mounted to low pro rod rack mounting system that has cable steering to move the shaft in circles but it is hard to see direction it is pointed at times.

I have a switch to turn power off to nmea200, so didn't have power to steady cast. It's accurate when steady cast is enabled

This last update with the compass heading was added to the direction icon. The icon for the live scope worked right before but now you can't rely on the icon to show you where the transducer is pointing. We have 2 Garmin units one on the bow and one on the console and are networked together. I fish out of the back seat and did rely on the icon to show me where the fish are to be able to cast to them. So with out the icon being accurate I am asking my son what direction is the transducer is pointing due to not being to see the pointer. Where as before all I had to do was to look at the icon on the console unit. I hope that Garmin will fix the software to correct the problem.. That's one of the reasons we chose to replace the Lowrance with another Garmin unit...

As several stated above, the solution to having an accurate LiveScope view cone icon is to add a heading sensor via NMEA2000, either the SteadyCast or the 24xd.

I have no heading sensor and same issue with my 94sv. I just don’t worry about location of the icon anymore.
fishysam you said you have to calibrate when switching between perspective vs forward/down? So I’m in forward mode and switch to perspective I have to stop fishing and spin in a circle to calibrate and then back to fishing? I just installed perspective mode mount to trolling motor and haven’t got out to test.

When changed to Perspective Mode, to best enable this view shift the AHRS system is reset. As such, yes the compass calibration is wiped out. Keep in mind the compass calibration is really only needed if you are going to drop waypoints in front of you from the LiveScope return.

Have to move for arrow to work I believe

[dricha21]

I have a heading sensor puck installed for my ultrex. Is there a way to use that to tie in to my garmin or are they not compatible to help with the cone on my boat icon?

[Gaskincrew]

Heading sensor still does fix it !! Wasted 200$
