6.Using Bottom Lock; Factory setting; OFF
Bottom Lock provides an up-close view like Zoom, except that in this case the zoomed view automatically moves up or down to stay on the bottom. To use this feature, select BOTTOM LOCK and press ON-OFF. The range of the display is shown when bottom lock is on and a "BL" appears by the bottom range number.
This is an ideal feature for finding structure or locating fish near the bottom.
Remember; If bottom Lock is the last function selected, you can use the ON-OFF button to switch Bottom Lock on and off without having to press select.
7.Selecting Fish ID; Factory Netting: On
When you turn the Ultima on, the unit automatically sets Fish ID to the On position. To turn the ID feature off, and display fish with pixels instead of the ID icons, press the ON-OFF button while within the Fish ID menu. Pressing the ONOFF button again reactivates the ID function.
