other internal and external medical devices. The interference can be severe and cause malfunctions.
Individuals wearing such devices should not handle strong magnets. If any user has any type of
electronic, mechanical, implanted, or external medical device, they should consult a physician and
the manufacturer of the medical device to determine its susceptibility to static magnetic fields prior
to allowing them to handle the LYNCS™ system. All magnetic products should be kept at a safe
distance from individuals with such devices.
Finger Trap
Due to the powerful magnets involved care must always be taken when handling and using the
LYNCS™ system, especially when deploying and removing the scanner from the inspection surface
as the system will exhibit a strong attractive force and present a finger trap.
Loose ferrous material such as tools, metal objects or magnets will be attracted to the systems
magnetic wheels and may cause injury as they move towards them. Always ensure to work in a
clean area, carefully follow handling instructions and be vigilant.
Laser
The LYNCS™ system utilizes a Class 1 laser for scanning guidance. While laser protection eyewear is
not normally necessary, do not deliberately look or stare into the laser beam. Avoid accidental
exposure to eyes. Do not aim at aircraft or vehicles, it is unsafe and illegal.

2. Introducing LYNCS™
LYNCS™ is an advanced modular ultrasonic inspection scanner that has been designed by experts
to provide Phased Array corrosion mapping and weld integrity assessment. It is the first truly
versatile system that allows users to interchange between weld inspection and advanced corrosion
mapping in less than a minute. While primarily designed to work with an Eddyfi PA UT instrument,
it can be utilised with other third-party PA UT instruments.
The LYNCS™ system is offered as one of three available packages, the LYNCS WI for weld inspection,
LYNCS CM for corrosion mapping, or LYNCS FULL for both weld inspection and corrosion mapping.
LYNCS WI weld inspection configuration can accommodate up to 6 PA and/or TOFD probes and
has a dual-bar structure for enhanced stability and probe placement accuracy. It is a toolless
scanner with an interchangeable design, making it ideally suited to all weld inspection
configurations.
LYNCS CM corrosion mapping arrangement is ideally suited to vessel and pipework inspection. It
has an extremely low profile and lightweight design, making it the most suitable option for rope
access deployment and heavily congested pipework.
LYNCS FULL combines both the weld inspection configuration and corrosion mapping arrangement
in one package.
LYNCS CHAIN is an accessory that bolts onto the scanner and opens up weld and corrosion
inspection capability to non-ferrous piping such as stainless steel and HDPE. The design offers
incredible alignment and stability whilst maintaining full use of the LYNCS system’s market leading
advantages. There are three different available options, based upon the range of pipe outer
diameter to inspect:
•LYNCS CHAIN 4-32 to work of a range of outer diameters pipes from 4in (101mm) up to 32in
(609mm).
•LYNCS CHAIN 4-12 to work on a range of outer diameter pipes from 4in (101mm) up to 12in
(304mm).
•LYNCS CHAIN 12-32 is an expansion kit for the LYNCS CHAIN 4-12 by increasing the working
range of outer diameter pipes from 12in (304mm) up to 32in (812mm).
