Side-by-side buyer comparison of Waygate DMS Go+ against direct-competitor ultrasonic thickness gauges (Waygate DMS 2, Krautkramer 27MG, Olympus 45MG / 27MG, Dakota MMX-6 DL+, Mitech MT160, Sonatest T-Gage+, Cygnus 4+ Multi Mode) for marine hull inspection and process-piping corrosion mapping. Range, resolution, mode, screen and shortlist rules by job.

Ultrasonic Thickness Gauge Buyer Comparison — DMS Go+ Class

The GE / Waygate DMS Go+ is the reference ultrasonic thickness gauge for marine hull inspection and process-piping corrosion mapping. It has a 5-inch sunlight-readable colour display, dual-crystal probes for through-paint measurement, A/B-scan storage and 0.01 mm resolution over a 0.6–635 mm range. Every gauge in the same buyer class shares the same core capability (dual-crystal pulse-echo with a coating-echo mode) — they differ in probe library, IP rating, data-logging model and shipboard survivability.

Model	OEM	Range	Res.	Mode	Screen	Notes
DMS Go+	Waygate / GE	0.6–635 mm	0.01 mm	PE + PECT + A/B-scan	5 in colour, sunlight-readable	Marine hull + process piping standard. B-scan storage.
DMS 2	Waygate / GE	0.6–508 mm	0.01 mm	PE + PECT	5 in mono LCD	Predecessor — still in service, no A/B-scan.
Krautkramer 27MG	Baker Hughes / GE	0.15–508 mm	0.001 mm	PE (through-paint)	5 in mono LCD	Coating + metal thickness in one shot; superseded by DMS Go+.
Olympus 45MG	Olympus (Evident)	0.08–635 mm	0.001 mm	PE + PECT + A/B-scan	5 in colour, EL backlit	Direct competitor. Broader probe library.
Olympus 27MG	Olympus (Evident)	0.15–508 mm	0.001 mm	PE (through-paint)	3.5 in mono	Coating-thickness (echo-echo). Compact, hull-side popular.
Dakota MMX-6 DL+	Dakota Ultrasonics	0.6–500 mm	0.01 mm	PE + A/B-scan	4.3 in colour	Cost-effective competitor; ATEX version available.
Mitech MT160	Mitech	0.75–300 mm	0.01 mm	PE	3 in mono	Handheld low-cost. General hull spot-checks only.
Sonatest T-Gage+	Sonatest	0.5–508 mm	0.01 mm	PE + PECT	4.3 in colour	UK-made. Popular offshore inspection.
Cygnus 4+ Multi Mode	Cygnus	0.5–250 mm	0.05 mm	Multiple-echo	3.5 in colour	IP66 splash-proof, marine hull inspection standard next to DMS Go+.

Shortlisting by job

Class survey (LR / ABS / DNV) — DMS Go+ or Olympus 45MG. Both accepted without further calibration paperwork.
Bulk hull thickness spot-check — Cygnus 4+ or DMS Go+ (through-paint dual-crystal probe). IP66 splash resistance matters on deck.
Corrosion mapping with data logging — DMS Go+ B-scan and thickness-grid storage or Olympus 45MG with GageView Pro.
Cost-controlled routine survey — Dakota MMX-6 DL+ or Sonatest T-Gage+ give 90 % of the DMS Go+ capability at 60 % of the price.
ATEX-rated tanker deck — Cygnus 4+ Multi Mode (marine ATEX) or Dakota MMX-6 ATEX. The DMS Go+ is not intrinsically safe.
