Hi @nfored,
The new specifications will be available at release, but I can say the range will be increasing. The transducer beam is narrower, which reduces the area covered by a given ping, but means the transmission spreads out less as it travels, so more of it gets back at a detectable level from reflections that occur further away.
Note that the usual physical caveats still apply - if the target surface/object does not reflect much of the pulse back towards the sonar then it will not be detectable.
