1. Resolution is the number of vertical and 

horizontal pixels your display is made up of.

2. Vertical Pixels (Height) - As we are dealing with 

depth, it is obvious that vertical resolution is 

important for traditional and DownScan sonar.  

An interesting observation is that the Elite4 has 

the same VP as the HDS9 Touch.

3. Horizontal Pixels (Width) - SideScan resolution 

is dependent on horizontal resolution.  

Horizontal resolution also plays a role in the 

quality if the image when it comes to History 

Resolution which is effected by boat speed and/or 

display scroll speed.

Tip: Too many pixels on a physically small display can be just as detrimental as too little on a large display.
