A few simple
tips can help you select the best transducer for your boat and fishing
style. A properly adjusted and installed transducer maximizes the performance
and enjoyment of your siren and helps you fish more efficiently.
While all
transducers perform the same general function, consider a variety of mounting
styles and styles. Some are designed to provide depth information only, while
others, called "Tri-Ducers", provide the siren with information about
depth, boat speed, and water temperature. This additional information can be
very useful for fishermen.
Some information on mounting types /
styles:
Transom mount transducers. This style transducer is very
popular for small fishing boats, skiffs, and boats stored on trailers. They are
ideal for boats with an outboard motor or I / O in any material, including
aluminum. The transducers mounted on the stern mirror are often installed using
a lifting bracket to prevent the transducer from breaking if it strikes an
object (or the trailer during loading). Due to their relatively small size,
these Airmar Transducer are generally 600W. Although it has limited power, a typical
dual-frequency mirror setting of 50/200 kHz is a good and versatile transducer
for a variety of applications.
Thru-hull transducers.
Skin-to-skin transducers provide excellent performance for large anglers. For
installation, a hole must be drilled through the hull, and the transducer is
often mounted with a high-quality fairing that keeps the transducer parallel to
the waterline for a vertical beam and maximum energy directed downward. Another
type of helmet that is becoming more and more popular through the skin is the
recess through the helmet. This transducer is mounted flat on the bottom of the
boat and has an inclined element in the housing to compensate for the fall of
the boat. Most skin Airmar Transducer is powerful 1 kW or 2 kW units suitable for
professional color sirens and serious offshore applications. The most common
through-hull transducers use bronze housings that work with fiberglass, wood, and other hull materials. Stainless steel helmets are also available. Plastic
through hull models is available for boats with an aluminum hull to prevent
galvanic corrosion of various metals.
In-hulltransducers. Mounted on the
hull and sending your signal through the bottom of the hull, this design is a
great solution for powerful fishing boats. On the positive side, there is
nothing under the hull's rolling surface that affects the performance of the
boat at steering speeds. For the same reason, these Airmar Transducers follow the
background very well at higher speeds. Plus, you don't have to worry about
ocean growth and maintenance issues, and if you ever need to remove it, it's
easy to do without towing the boat. However, there are some tradeoffs. The
internal helmets are large to compensate for the loss of signal from the helmet
and must be in a small mineral oil tank. Therefore, you must have enough space
to mount the unit on the hold of your boat. In addition, barges are only
recommended for rigid glass fiber bottom boats, and the use of separate water
speed and temperature sensors is required (if you wish this information).
Some thoughts on power. The size/power of your best transducer for your boat must match the siren for optimal performance. For the many small recreational
fishing boats equipped to fish in coastal or offshore waters, a 600 W transom
or through the mirror is sufficient. Those who need to mark structure or floating
fish in deep-sea canyons, as well as serious tournament fishermen, will benefit
from a powerful 1 kW or 2 kW siren and a transducer through the skin or on the shell.
Broadband, CHIRP, Sidescan,Downscan etc.
Some new transducers are designed with broadband ceramic elements, so compatible
high-end sirens can "dial" a range of high or low frequencies to
maximize performance depending on conditions. Recent advances in High Intensity
Compressed Radar Pulse (CHIRP) probe/transducer accessories technology provides detailed
background image results never before possible. But it has a higher price and
it is not necessarily the best option for any type of fishing. In the same
vein, new side scan and down scan technologies allow boaters to see more detail
and find boat targets.
