Included equipment — towed-system manual rev 9

System equipment: Towfish with cable, top-box, universal AC/DC adapter and international plugs, fused cigar-plug DC lead, cigar-socket/crocodile-clip lead, USB A/B cable, Scanline software/driver USB drive, guides, reusable cable tie and sundries.
Advanced system option: Waterproof rigid transit case, USB GPS receiver and pole-mount bracket.
Host requirement: Windows-compatible computer with a free USB port; a suitable DC battery or protected AC outlet is required.
Tow cable limits: Manual lists breaking strain greater than 150 kg and minimum bend radius 30 mm. Confirm selected cable assembly.
Mechanical drawing note: The operating manual swaps width/height labels relative to the current datasheet. Use the approved dimensional drawing for mounting.

Configuration options

Tow-cable lengthIntegration

20 m and 50 m tow-cable lengths are listed. Confirm cable assembly and mating connectors.

Advanced system packageOptional equipment

The towed-system manual describes an advanced package with transit case, USB GPS receiver and pole-mounting bracket. Confirm current package contents.

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.
