Lowrance LiveSight works without a module on HDS Live with the latest software.
Previously software 22.1-65.1.18 was the latest softwareversion for HDS Live that allowed the use of the LiveSight transducer without the PSI-1 module. From software 22.1-65.1.22 and onwards the module was required. But the latest softwareversion (23.3-67.3.33) will again allow HDS Live users to use LivSight without a module. (All HDS Lives made from September 2022 and onwards require a module for LiveSight regardless of software, as these units have a different chip for sonar versus the earlier units.)
