Taking Snapshot on Humminbird Helix 10

It is suppose to be easy to take a snapshot on a Helix. Put a SD Card in the slot. Just go to "Accessories" om main menu and scroll down to waypoints (can't recall exact name). Then when you see the screenshot you want, press "mark" Just like a waypoint. In fact, it does record a new waypoint. NOW, here is my problem. I didn't know my card (ScanDisk) had to be formatted. So after first failed attempt at a scrteenshot I formatted the disk. The next day I tried again. When i put the disk in my computer. I got a message that said the card was "locked." So I finally learned how to unlock the card (push the slider on left side of card up). The next time I go out I'll try again. I have read a lot about these micro-cards which makes me wonder if my next attempt at a screenshot will be successful. My disk is only 128 MB, I don't know if that is big enough or not. Also I read something about having a speed rating of 10. I don't see any such rating on my card. I'd appreciate any advice.

Check out amazon. you can find samsung 32 gb cards for about 8 bucks. 128mb is pretty small if you plan to save pictures

That card is way too small capacity. The new Sandisk come already formatted FAT32, I never format them. When you see something on screen you want to take a screen shot of, just hold down the "Mark" button, and it will take a shot without any menu rigamarole.

Just to clarify ...:

Press and hold the Mark button for 3 seconds until you get a popup that says .PNG successfully saved ...

The only Menu option for waypoints is “if” you also want to create a waypoint at the exact point where you created the ScreenShot - this has to be enabled under the Accessories tab in “Create waypoint with ScreenShot” ...

SD Cards must be 32gb or less ...

Slower write SD Cards can be used - they just create a “lag” between the time that ScreenShot is initiated and the time that the unit returns to live sonar imaging (simply because the slower write SD Card needs more time to write the ScreenShot data to the SD Card) ...
