Lowrance guys quick question

Going to be upgrading my electronics this week and was wondering how you tell the difference in Gen1/gen2 and lss1 transducer and lss2?

I have a HDS 8 and HDS-7 with structure scan module and they are all linked up that I will be selling just want to be sure I label it correctly

Regards,

Gen1: not touch has buttons to scroll through programs
Gen2 touch, no buttons to scroll

Lss1 takes module mounted in boat
Lss2 is buit in

Hds 7 or 8 Gen 1-- HDS and Lowrance letters on front of graph will be blue or gray.
HDS 7 or 8 Gen 2-- HDS and Lowrance letters on front of graph will be white.
LSS 1 module will say Structurescan
LSS 2 module will say Structurescan HD
LSS 2 transducer is 10" long
LSS 1 transducer is shorter

Some Gen 2 is touch and some Gen 2 is buttons.

Gen 2 Touch does not require module to run structure scan.
