I have Humminbird Helix 5 SI GPS sonar.
I have bought the Reefmaster Sonarviewer program yesterday.
In the Program can i not see the Downscan Pictures,/Chanell . It is on the Screen : “Not available” .???
Then i send same Sonar .DAT files to Reefmaster Ltd.
Here is the Answer of Reefmaster Ltd:
Your recordings do not contain the downscan channel, which is present in the B004.SON file. Your recordings contain B000-3, which includes primary, secondary and Sidescan port/starboard.
Some Humminbird units "fake" downscan display by rotating and superimposing both sidescan channels, and this is probably the case for your unit. They do not run or record a separate sonar channel, and consequently we do not display it within the Sonar Viewer.
All of the "downscan" information that your see on your unit is present in the sidescan display.

I thought that the Humminbird Helix 5 save all frequencies (Including 80 , 200 Hz , Downscan and Sidescan).
I can switch between screens on sonar, it does not affect backups.
In HumViewer can i see downscan too. !?! (Not nice...)
What's the problem? It's in my Humminbird Unit or in Reefmaster?
This deception of customers ???! ???
HELIX 5 SI GPS have not a real Downscan only Sofware trick.
Therefore, a low cost of HELIX 5 SI ?
What do you think about this?
