Couplant Free Transducers (2 - 5 Mhz)

Would like to hear about anyone's experience applying "Couplant Free Transducers". Specifically “wheeled transducers in the 2 – 5 Mhz range. We are currently considering using this technology and want to hear pro's and con's. Would be grateful for any feedback, positive or negative.
Regards, Rich Roberts

Re: Couplant Free Transducers (2 - 5 Mhz)
Silverwing makes an extremely rugged and HIGH PERFORMANCE wheeled transducer which is available in several versions of products made by both Silverwing and NDT Automation. These includes both manual B-Scan and C-Scan systems as well as fully AUTOMATED, high-speed C-Scan systems.

There are technical differences between conventional pulse-echo transducers and wheel transducers - which are essentially dual-element designs - which can be an issue for SOME applications - but for most situations - the "only" difference is the fact that the wheeled design can be used WITHOUT COUPLANT. (For extremely corroded materials with significant FRONT SIDE corrosion, a standard - water coupled - pulse-echo design will provide somewhat better performance - and that factor would be the "only" operational limitation). The up-side (of course) is the operation of these transducers without the need for water or gel couplant.
