MENU FUNCTIONS

After an adjustment is made, the menu disappears and the new sensitivity setting is in affect. If additional time is needed to study a menu, press and hold the MENU button and the menu will remain on-screen indefinitely. If you need to make an additional adjustment, press the UP ARROW or DOWN ARROW button.

Depth Range. The Depth Range function controls the vertical distance displayed on the graphic area of the display. There are

nine depth ranges available. The top of the range is always 0, or the surface of the

water. Ranges of 0–15', 0–30', 0–60',

0–120', 0–180', 0–240', 0–360', 0–480', and 0–600' are available. In the metric version, ranges of 0–5, 0–10, 0–20, 0–40, 0–60, 0–80, 0–110, 0–150, and 0–185 meters are available.The range that positions the bot- tom depiction closest to the bottom of the screen, will best utilize the avail- able display resolution.

The Tracker unit automatically adjusts the depth range depending on the depth of the water. The unit tries to maintain the bottom depiction about ²⁄₃ down the total range (for example, in 20' (6m) of water, the 0-30' (0-10m) range would be select- ed). This provides the best display resolu- tion and therefore the best target separa- tion possible.

The Depth Range can be adjusted manually. Press MENU repeatedly until the Depth Range menu is visible. Two options are available: Auto and Man- ual.

The manual setting enables you to adjust the current depth range setting. The unit no longer adjusts the Depth Range to the most appropriate range for bottom dis- play. Often, the bottom may not be visible on-screen. The digital depth readout
