Reading Lures or Bait
- The
VX-1i
will pick up and display small objects like
lures or bait. When tuning the unit to display your lure or bait, lower the object
to the desired depth and turn up the GAIN until you see the lure or bait on the
display. It is important that the GAIN be set so it displays the lure or bait as
you raise or lower it.
NOTE: Too much GAIN will cause clutter and may make it difficult to
distinguish other targets like fish near the bottom. When tuning the unit to
display lures or bait, make sure that the objects are in the center of the hole
and therefore in the center of the transmit beam. If there’s water current (some
lakes have underwater current or movement) and the lure doesn’t weigh
much, it may move to the outer edge of the signal or out of the transmit beam
altogether. This will make it difficult or impossible to pick it up on the display.
Dead Zone
- All sonar units will have a dead zone in certain circumstances.
This occurs on sharp drop-offs where the transmit beam (cone) hits the
shallower edge of the drop-off and returns before the deeper edge returns.
This in effect creates an undisplayed area between the shallower and deeper
water within the transmit beam.
Open Water Set-Up
The VX-1i is an excellent sonar unit for open-water use. To convert the
VX-1i
from an ice system to an open water unit, remove the
VX-1i
powerhead from
the electronics shuttle. A new gimbal bracket is supplied with the open water
transducer kit and can be mounted on any flat surface. The unit should be
mounted in a location that is free from other electrical apparatus to eliminate
interference. If interference is observed, reposition the unit until optimum
performance is obtained. Your boat’s 12-volt DC electrical system can be
used to power the unit.
The
VX-1i
is protected from accidental polarity reversals. No damage will
result from an incorrect battery hook-up. The ice-fishing transducer supplied
with the Ice System is not designed for open-water use. There are two trans-
ducer choices for use in open water. The high-speed transducer is designed
for transom mounting (outside the hull) and reads depth while the boat is on
plane. The puck-style transducer is most often mounted on the bottom of a
trolling motor or epoxied into the hull of a fiberglass boat.
High-Speed Transducer Installation
High-Speed transducers are designed to be mounted on the transom of a
boat. If properly installed, you will be able to read depth, weeds, and fish while
the boat is on plane. Transducer mounting location is critical for optimum
performance of the
VX-1i
sonar unit. The mounting location should be free
of
any white water or turbulence resulting from rivets, ribs or hull strakes. It
is preferable to mount the transducer at least 18 inches from the centerline
of the boat to avoid turbulent water resulting from the outboard motor. The
transducer is wedge-shaped and should be mounted with the leading edge
mounted against the transom. The leading edge of the transducer should be
mounted flush with bottom of the boat. This can be best achieved by using
a flat object like a ruler and holding it flat along the bottom of the boat and
matching the bottom of the transducer to the bottom of the boat. Attach the
mounting hardware to the high-speed transducer as shown in the instructions
