Dense schools will show you a stronger color, while schools that are more spread out will have a
weaker signal.
Also, keep in mind that some fish will give you a signal stronger than normal because of their air
bladder size and their bone structure.
Of course, the best way to learn to read your CVR is to use it- especially in familiar locations. If
you know what’s underwater and can see it displayed on the screen, then you’re on your way to
being an experienced CVR user.
OPERATING THE CVR 1000
Power On/Off:
Pressing this button once turns the CVR 1000 on. Pressing it once again turns it off. When the
unit is turned off, holding this button down for about 2 seconds activates the built-in simulator.
Stop:
By pressing this button once, you can stop or “freeze” the display. Pressing the button once again
restarts the display at its previous speed setting.
Color Bar:
You can call up the color bar on the screen by pressing this button once. The color bar will
appear on the far left side of the screen and will remain there until you press the button again to
turn it off.
Select System:
The CVR 1000 Select System commands an amazing number of functions with only four buttons:
Select, Up and Down arrows, and On/Off.
When you press the Select button, each function appears in a block on the screen with easy-to-
understand instructions for using the function. You use the Up and Down arrows and the On/Off
button to adjust the functions. Then, the instructions disappear, returning the display to its full
screen reading.
Select System functions are “active”; that is, the last function displayed on the screen can be
adjusted without pressing the Select button again. This is valuable in two ways.
Example 1: Readjusting a function
If bottom alarm was the last function used, you can adjust it again by pressing one of the
arrow buttons or the On/Off button.
