BOAT USE
Navigation
The Vexilar FL-8, FL-12, FL-18 and FL-20 flashers 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 flasher
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 flasher as the ultimate source of information.
Use good judgement as well.
Bottom Content
The Vexilar FL-8, FL-12, FL-18 and FL-20 flashers 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.
