To adjust the sensitivity, press the SENS key. A menu appears on the right side of the screen as shown on the previous page. Press the right arrow key to increase it, the left arrow key to decrease it. When you have it changed to the desired level, press the CLR key to erase the menu or wait a few seconds for it to automatically clear.

3D OPERATION

When the X-70A 3D is in the 3D mode, the Fish ID feature is always on (unless you turn it off). FishTrack (the depth numbers above the fish sym- bols) shows you the depth of the fish symbol and can be turned off, if desired. See the FishTrack section in this manual for more information.

3D RANGE

The range is set by the unit as long as it’s in the auto mode. However, you can adjust the range slightly when automatic is on. The unit won’t let you move the bottom off the screen, and it will correct the range once the bottom begins to go off the screen. When the unit is in the manual mode, you can set the range to any that’s available.

To change the range on the X- 70A 3D, first press the RANGE key. A screen similar to the one at right appears. Simply press the down arrow key to in- crease the range or the up ar- row key to decrease it. When the desired range is chosen, wait a few seconds and the menu will automatically disap- pear from the screen or press the CLR key to erase it.

The X-70A 3D uses the following ranges: 0 - 5, 10, 20, 40, 60, 80, 100, 150, 200, 300, 400, 500, 700, and 900 feet.

3D ZOOM

The zoom feature enlarges all echoes on the screen, making them easier to see. This feature works in automatic or the manual mode. (Note: If the unit is in the 3D automatic mode and the zoom feature is turned on, the unit will not change the range to a shallower setting. If the bottom signal goes shallower than the zoom range, the X-70A 3D will simply show a flat bottom signal at the shallowest range shown on the display. For example, if you have a zoom range from 45 to 60 feet, and the bottom rises to 30
