Hopper3 Manual

Excellent! That $100 is money well spent. Many, many years ago I paid $100 for an upgrade to a 722 in place of of a 612 that they wanted to install. I never regretted that.
Isn’t the only difference between the 722 and 612 the fact that you can have a second TV connected? Or am I missing something? (Sling compatibility?)
 

Replace Joey with another H3

Max length of coax between Hopper3 and Joey3?
