I just got a Livescope LVS34 and need to upgrade head units.

The choices I'm considering in the $1k range are:

  1. UHD2 93SV w/GT56($1,199)
  2. Ultra 106SV w/GT54 ($999) W/GT56, it's $1,819- a bit much.


Which is a better head unit, the UHV2 93SV or the 106SV Ultra? Anything in particular stand out?

I initially like the 106SV with both fresh and saltwater maps, since I fish both. Are the included maps decent, or will I end up buying upgraded maps?

Secondly, is the difference between the GT54 and the GT56 transducers a night and day difference?

I'm way behind in my knowledge, so I appreciate any help. Thanks in advance!
