Upgrade to UHD/LVS34 for $200+ over
Upgrade to UHD2/LVS34 for about $700+ over
My opinion :
#1 ... from what I've read, no it's not $1K better (unless you need deeper & farther scanning ability.
#2 ... Unless you have use for the added features of the UHD2 ... no, it's not really worth the extra $$.
#3 ... My buddy upgraded to the 106sv, from the 93sv, in order to be able to see fish that were on the bottom better ... and he's been slightly disappointed in that regard. I've fished with him & haven't noticed any real difference in what the screen shows vs what his previous 93sv unit showed.
Also of note that I noticed when comparing the UHD vs UHD2 is that the UHD2 draws +/- twice the power ( Garmin | Product Compare ) That "may" require a more substantial battery to accommodate the increased power draw.
Thanks CrappiePappy, I appreciate your experience with the various products!
Interesting is the fact that the 93SV UHD2 is actually a couple hundred bucks more expensive than the 106SV. I need to pull up the specs to see if it's actually a better unit.
