Humminbird TCR ID-10 manual

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-71/2 feet in the 15' and 30' ranges, and 15 feet in the 60' and 120' ranges and 30 feet in the 180', 240' 360' and 480' 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.

7.Depth Range Automatic setting: on

The TCR automatically finds the bottom, and then sets and displays the ideal depth range when you turn the unit on. If you choose to leave the auto range change on, the bottom will remain "blacked in" for easy-to-understand readings, and the depth ranges will change automatically.

Or, you can turn the auto-change off, allowing you to change the depth range manually. In this mode, the bottom is not blacked in.

This lets you see a double bottom echo, which is preferred by some fishermen because the width of the second echo can indicate bottom texture.
