Getting ready to buy and SD card for my HDS7.  Are there any specifics I should be aware of?  Size?  Speed?

Manufacture?

    I think the max hds units can take is 32gb. I have a 32gb in my hds gen 2 8 and it shows I can record 4.5 days worth of sonar logs with all channels recording. As far as type I don't see a difference between the high end sd cards and just the regular ones.

    I would go ahead and get a 10 speed card. It allows for fastest transfer rate. I don't know for sure that it needs it, but it won't hurt.
