[Acoustics] mode use for slow vel

[David M Hernandez]

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?
