Roy is right .... I'm in my Livescope system to the tune of about $2500

Livescope & Garmin 93sv UHD $2200 (no tdx for 93sv)
68AH AGM battery $200
Cumberland Crappie mount $100 (no longer made)

I already had a Hook 7 mounted at bow (tdx on TM), which I now use mostly for maps/waypoints. That's the reason I bought just the head unit for the 93sv, plus I wanted the whole screen dedicated to Livescope & not have to split the screen or constantly be switching screens. Plus I didn't want to have to move the Hook & its tdx.
The CC mount was added behind the Hook and can be raised up to almost 2' if needed.
The dedicated battery was purchased to run the 93sv & LS, because together they can pull 2-4 amps/hr.
