Compatibility and naming

The current support page links a Hull-Mounted System Manual whose internal specification names the older 450H. It is retained as a clearly labelled mounting/operation reference; its 450 kHz specification is not applied to the current 1 MHz 992H. Request a 992H-specific manual and resolve the 5 m / 20 m cable discrepancy before integration.

Acoustic performance notice

Range is specified per channel; total swath is twice the per-channel range. The transducer depth rating does not apply to the topside box, whose IP50 enclosure provides no water-ingress protection. Maximum range and resolution depend on survey conditions and setup.
