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

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.
