buckshot,
thank you for your inquiry.
on TZT2 software version 4.01 and later a "point density" selection was added. to find this selection press; Home---Settings---Points---Points Density.
set to Low, Medium, or Full depending on your preference.
Finally, you will also find in this menu a section the ability to adjust the size, shape, & color of the point icon that is displayed on the chart plotter screen. In some cases simply adjusting the size of the icon can help to visually declutter the appearance of the screen.
