[Acoustics] WM5 stops to work well

[Paulo Everardo Muniz Gamaro]

Hi Nick

Thanks, for your comment
I have achiving great measurements in this mode in his high limits, of
course higher you told me because is a 600
but here my problem is the contrary.

 I am measuring in a 1 meter depth, and near zero velocities, flat bottom ,
so I think, or I am under his low limit, or a problem in the
hardware/firmware.
 It suppose to work, if I took : 10 cm depth cell, 25 cm blank, 10 cm
draft, plus around 10 for another cell would give me 45 cm as a minimun
depth, which is less then the minimun depth required (65 cm) , but  both,
less then the meter I measured.
 Or we have a third option here, low limit is not what we think in real
life.

Have any of you measure in such condition with a 600 khZ ?
Which is the shallow measurement you did with a 1200 ?

Cheers

Paulo
