SD Chip Type

[ibmack]

need a SD chip for my new hds7 gen 2 touch, but can't find anywhere in the Lowrance manual where it tells you which one. there are several types and I need to make sure I get one that is compatible.

can anyone steer me?

Are you talking about a mapping chip like from Navionics or just a blank chip? If a blank chip, any SD chip around 4 to 8 Gig will work. I have the Navionics Platinum in my HDS7 touch, but you need to buy one based on your geographic area. They are divided into sections of the US.

just a blank chip so I can back up, save screen shots foe examination later, etc. so just any sd chip will work ok on the lowrance. thanks.

hmmm, actually that was my real question. I know some types work for certain apps and systems on readers I use on my computer.
