[cool][#0000ff]As long as the bottom of the transducer is in contact with water...continuously...it will send and return signals. Running it only an inch or two deep will work fine. Any deeper and you increase the potential for hanging up on weeds and for getting your line wrapped around it while fighting fish.[/#0000ff]

[#0000ff]The transducer should always point at a 90 degree angle to the surface of the water. That will shoot the beam straight down. The greater the variance in the angle the less true the display will be and the greater the chance of "off" readings. When the beam strikes the bottom at an angle it is the same as shooting straight down over a steeply angled bottom. The sonar cannot produce an accurate display because the returns are constantly changing.[/#0000ff]

[#0000ff]You will always get some "rock and roll" while fishing from a tube or toon, but that is not nearly so much of a factor as not having your transducer beam shooting straight down...as much as possible.[/#0000ff]
