I would look into buying lightly used LVS32 (get the single cord version) with an EchoMap93UHD (Scheels has a 93UHD2/LVS32 shuttle bundle for $1,800 brand new), that setup can get down to around 18 lbs and run all day on a 20AH battery. you should be able to find really good deals with all of the folks who just upgraded during the black Friday sales…
This gets you to about 80% of what the top of the line LVS34 FFS setups can deliver for a fraction of the price…if it turns out you like using FFS and want to upgrade, then you’ll be ready for when Garmin/Lowrance release their 2.0 versions in the future and you won’t take that big of hit when upgrading like the LVS34 owners will… or maybe you’ll be happy with the LVS 32 and just keep it…
if you end up not liking FFS, then you should be able to sell it for decent price to somebody else looking to get into the FFS game…
