spnb8 well first off welcome to the forum when you get your units get online
go to HB support register your units then you can go to your account and
see the latest upgrades. you will need to download HB PC on your desktop
You can down load humviewer from this forum to your desktop.when you get your new HB"S go out on the lake take snapshots and take recordings
they will both go on your sd card.take your sd card out and put it in your pc
open the drive you will see matrix that will go to HBPC the snapshots can be opened by the pc viewer the recordings will need to be opened by humviewer or another 3rd party viewer.I use yellowfin and humviewer
good luck . Gary
