[cool][#0000ff]Welcome aboard.[/#0000ff]

[#0000ff]What are the arches? They are a visual display of the air bladder inside the fish...the larger the arch the larger the air bladder. [/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]The display on a moving boat is more likely to be an arch because of the speed. In a float tube, at lower speeds, it will show up as a line...or series of dots...even with the chart speed adjusted. Most sonars are not designed for stationary or slow movement...like tubing.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]For this reason, usually leave my display set on Fish ID. Serious boaters scoff at that but if you learn to use it and read it the ID feature is more tuber-friendly.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]Where you have the transducer mounted there is no danger of "turbulence" from the fins. However, there is more potential of damage to the transducer while you are launching or beaching your tube. I suggest rigging a rotating arm for your transducer, like the one in the picture attached. This allows you to raise and lower the transducer...and to adjust it if it is not shooting straight down.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]You can actually mount the transducer to the end of a piece of wood and attach it in the middle to your strap so that it swivels up and down.[/#0000ff]
[#0000ff][/#0000ff]
[#0000ff]Good luck.[/#0000ff]
