L-707 SELF-CENTERING BORE ALIGNMENT SYSTEM
Hamar Laser manufactures the most accurate, versatile and portable bore alignment laser system available: The L-707.
Data taking targets include: self-centering, see-through, 2-axis and 4-axis targets, hand-held readouts and windows-based software to display and analyze data in real time.
L-707 Bore Alignment Lasers can be used for a variety of bore alignment and measurement applications: engine block bearings, compressor bores, shaft bearing bores, stern tubes and many more.
