[Acoustics] list of Sontek XR users

[Henry J Zajd Jr.]

Greetings all
                I am looking for anyone who are using Sontek XR velocity 
sensors and how long the units have been in place. I have some questions 
on compass headings,pitch and roll. 
                My units have been in the water since the late August of 
2003 and  I have noticed some changes to these readings that I would like 
to talk with you about.
