[Acoustics] mode use for slow vel

[Randy A Samuelson]

WM 11 should work great if the water is calm (no chop) and there is no 
significant shear in the column.  I've been using it with good results at 
sites with similar depths with velocities up to 1.2 ft/s.

That or WM11 a) if you have it and b) if you keep your boat speed down.

These conditions are ideal for water mode 5.

To all, The conditions are: Channel width 100 to 200 ft. Depth 3 to 7 ft. 
velocity < .1ft/sec. Used Rio 1200khz water mode 12sb bottom mode 5. Not 
sure it was the best combination for those conditions, does anyone have 
similar conditions? Which mode combinations would work best for collecting 
repeatable transects?
