Mike Adams Posted June 27, 2021 Report Share Posted June 27, 2021 I've had one for a few years now and it is very good and even works when the boat is in the water. Use plenty of coupling gel. One of the best value gadgets in my opinion. Link to comment Share on other sites More sharing options...

TheBiscuits Posted June 28, 2021 Report Share Posted June 28, 2021 (edited) My favoured professional surveyor thinks they are only any use as a hammer. His ultrasound kit cost quite a few thousand.

I was led to believe that it is not just about the 'machine' is showing but having the knowledge to interpret what the machine is showing. Link to comment Share on other sites More sharing options...

I was wondering that, If it gives good numbers when its about to fail or it gives poor numbers and you spend a grand plating good steel Link to comment Share on other sites More sharing options...
crosser Posted June 28, 2021 Author Report Share Posted June 28, 2021 i was thinking of testing it on a few different bits of steal etc first to get accuracy before trusting it.. Link to comment Share on other sites More sharing options...

It's worth mentioning that all the insurance companies and all the professional surveyors insist the hull thickness testing is done out of the water.

Mike Adams Posted June 28, 2021 Report Share Posted June 28, 2021 I can only speak as I find. Mine has proved very accurate. With a surveyor you are only buying some kind of insurance. They never do a very thorough job and often don't inspect internally and come with so many disclaimers anyway. Better off doing yourself and if in doubt get a very large hammer. 1 Link to comment Share on other sites More sharing options...
