Humminbird TCR ID-1 manual Zoom, Bottom-Lock, Display Speed

USING THE TCR ID-1

OPERATING THE TCR ID-1

Once the instructions have disappeared from the screen, it's easy to tell which alarm you have activated - the alarm for all fish shows both small and large fish symbols at the bottom of the screen, while the “large only” alarm displays only a large fish symbol.

4.Zoom

Automatic setting: off

When zoom is activated by pressing On/Off, it creates a “window” of expanded, up- close information. This window is marked by a cursor at the right of the screen and can be moved up or down with the arrow buttons. The exact depths of the upper and lower limits of the window are displayed as depth scales while you are in zoom.

The size of the zoom window changes as the depth range changes. The window displays 7½ feet of up-close readings in the 15’ and 30’ ranges, and 15 feet in the 60' and 120’ ranges. Keep in mind that, using your arrow buttons,

you can move the zoom window while the zoom is activated, without having to press Select again.

5.Bottom-Lock

Automatic setting: off

You can easily turn on the bottom-lock with the On/Off button. When on, this function shows up-close zoom readings in reference to the bottom. The size of the zoom window depends on the depth range - 7½ feet in the 15' and 30' ranges, and 15 feet in the 60’ and 120' ranges. The zoom window will automatically move up or down to stay on the bottom, with the cursor showing you the portion of the total depth range that is being displayed. This is an ideal feature for finding structure or locating fish near the bottom.

6.Display Speed

Automatic setting: one setting less than highest speed

The speed at which the TCR display moves depends on the display speed setting, and it is easily changed by pressing the Up arrow for a faster setting and the Down arrow for a slower setting. Generally speaking, the higher speed settings allow faster updates while slower display speeds provide more information.
