Rickie can you explain the other advantages the helix 9 SI have over the helix 7 SI beside networking?
HELIX 9 ...:

*Networkable
*Bigger screen
*Autochart Live built in
*Capable of utilizing the added 800kHz frequency of the XHS 9 HDSI 180 T
*2 full size SD Card slots
*3 preset buttons

HELIX 7 ...:

*Stand alone unit
*No AutoChart live
*Cannot utilize the added 800kHz frequency of the XHS 9 HDSI 180 T
*1 micro SD Card slot
*No preset buttons
