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 7 ½ 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-7 ½ 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
protion 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.
