It probably means there is no depth recorded in the sidescan channel, which the sonar viewer currently relies on. We are of this issue and working on a fix - it seems some recent Lowrance units/firmware revisions are recording sidescan in this way now, although that never used to be the case.
If possible it would be very useful to look at one of your SL2 files that exhibits this problem. If you are willing to share it, please zip it up and share to This email address is being protected from spambots.

sent through email while I look in to using WeTransfer
thank you

edit: ok, sent through WeTransfer

OK received, thanks. I will get back to you as soon as I have had a chance to take a look.

I'm having the same problem. I have a lowrance hook2 7. I'm glad to see that I was not doing something wrong. I'm very interested in your investigation of this issue and potential fix.

Hi Scott,
Sorry for the late reply. Is there any chance that you could share an example of a sonar log file that is not showing sidescan to This email address is being protected from spambots.

Hello,

I have the same problem. I'm using the Lowrance Hook reveal tripleshot and there seems to be no sidescan data.
I always abortet the convert to structuremap.

Matt,

sorry for the delay. I sent and email to the support address you provided with a link to download sample files from my sonar for you review.

Thanks,
Patrick

Has there been any movement on this issue? I have a Hook2 Tripleshot, and am also unable to view sidescan information in ReefMaster. As a new finder/rm user, I downloaded the trial, but won't be purchasing the product until/unless a resolution to this is published. Just looking for an update, what's the status on this?

Thanks for the file - all of these missing SS files are useful for our testing. There is movement here, and an update to come soon.

HI Matt,

any update on this issue?

It should be released for both RM and the Sonar Viewer by the end of this week.
