Pixel display method and apparatus

1. A sonar depth-finding device comprising:

a matrix of substantially rectangular pixels, each pixel having a first length in a vertical dimension and a second length in a horizontal dimension different from the first length, wherein a ratio of the second length to the first length is approximately an integer value N greater than one;

wherein the sonar depth-finding device is configured to display first information by independently activating individual pixels, and to display second information by operatively associating N vertically adjacent pixels to define a substantially square combined pixel; and

wherein first information includes sonar information and second information includes at least one of mapping and positional information.

2. The sonar depth-finding device of claim 1 , wherein the sonar depth-finding device is conligured to simultaneously display the sonar information and the at least one of mapping and positional information.

3. The sonar depth-finding device of claim 1 , further comprising a controller configured to operatively associate N vertically adjacent pixels to define the substantially square combined pixel.

4. A method of displaying information in a sonar depth-finding device, the method comprising:

displaying sonar information by independently activating individual pixels in a matrix of pixels, the individual pixels having a height and width, the width being greater than the height such that a ratio of the width to the height is approximately an integer value N greater than one; and

displaying simultaneously at least one of mapping and positional information by operatively associating N vertically adjacent pixels to define a substantially square combined pixel.
