Trying to understand the difference between these two transducers?

Am I correct in assuming they provide the same function just that the LVS32 requires the blackbox to work and the LVS12 doesn't and will work directly connected to a unit that can support it? Are they both the same quality?

The reason I'm asking is with the recent announcement of the new ECHOMAP Ultra units I'm considering going to that screen and the LVS12 to eliminate the blackbox in my setup. Would I lose anything by going that route (quality, processing, etc)?

Thanks,

Robert
