Bottom Lock; Zoom - VEXILAR FL Series Owner's Manual

Bottom Lock Zoom
( FL-18 Only )
Bottom Lock (BL) works the same as Auto Zoom, except the flasher continuously updates
the position of the bottom in the magnified view. This can be helpful in a boat that is
moving over varying depths or is riding in heavy waves.
Bottom Lock will keep the bottom reading lined up correctly with the zero mark on the
Zoom scale. This allows you to see objects which are very close to the bottom, even
though the depth may be changing rapidly. The range control must be set to a position
where the bottom is displayed in order for Bottom Lock to function.
FL-18 Bottom Lock (BL)
Activate Bottom Lock by switching the Mode control to
the BL selection on the right or the left. The right selection
operates Bottom Lock at the normal power level. The left
selection operates Bottom Lock in Low Power Mode.
IMPORTANT: Not for Ice Fishing. Bottom Lock works best for boats in motion. When ice
fishing, the Bottom Lock feature can incorrectly identify a large object slowly moving into
your view as a shallower depth change. The result is that the flasher adjusts to the new
level and the object is now displayed as the bottom.
Bottom Lock is only available on the FL-18.
Low Battery Indicator
The FLX-12 and FLX-20 series units will
give the angler a low battery warning
(10.6 volts) by flashing the green depth
lines around the inner side of the display
4 times every four minutes. At 8 volts, the
green depth lines will flash all the time just
before the system shuts down completely
(6.5 volts). All batteries are different and
how long you are able to fish after the first
warning will vary.
The FLX-28 displays a low battery message
on the display. See page 29.

Understanding the Zoom Modes
When Auto Zoom (AZ or BL) is active, the display is divided into two halves. When
reading depths always use the inner scale on the right side. Reading the overall depth is
the same, except only the right side of the display is used.
FL-18 - Auto Zoom
THE LEFT HALF represents the zoom
view. From the bottom up to six feet.
Read the distance from the
bottom using the inner
yellow scale.
The Zoom scale reads in the
opposite direction as the full view
scale. The bottom will always be at
the 7 O'clock position. Objects will appear
above this point. You can only see objects as far off
the bottom as the zoom setting permits, which is 6 feet.
Objects above this level will only appear on the right side,
which shows the entire water column.
IMPORTANT:
Zoom should be activated only when the transducer is submerged. If the
zoom is activated before the transducer is placed in the water, such as when moving from
ice fishing hole to hole while the zoom is operating, the bottom may not line up with the
zero mark on the zoom scale correctly. If this happens, simply switch the flasher to Normal
Mode and then back to Zoom to reset the feature.
THE RIGHT HALF represents the entire
water column, from the water surface
to the bottom. Read the depth
using the inner yellow
scale.
