BOAT USE

Navigation

The Vexilar FL series of ashers are great tools for navigation while boating. The

instantaneous readings offer the ability to identify depth changes quickly. Here are some

tips to help you navigate safely.

CAUTION:

• Be sure you know which range you have selected. If you think you have the asher

set to a deeper range than what it actually is, you may run aground unexpectedly.

• Be aware that although the depth displayed may be deep enough to navigate in

presently, shallow water may be dead ahead. Allow yourself plenty of time to slow

down if shallow water is encountered.

• If no bottom is displayed, assume the depth is extremely shallow. It may, in fact, be

deeper than the selected range, but never assume so without checking ﬁrst.

• Use common sense. Do not trust the asher as the ultimate source of information.

Use good judgement as well.

Bottom Content

The Vexilar FL series ashers are also great tools for determining bottom content changes.

The colors allow you to easily see when the bottom changes from one type to another.

ha r d o r So F t Bo t t o m

• Hard bottoms will generally appear as a narrow band with color content of mostly red

and orange.

• Soft bottoms will appear a wide band with more orange and green than red.
