Fish Finders-How to Choose a Transducer

What blazon of bend Finder Transducer do I charge for the blazon of Fishing I do?

The advice about bend finder transducers can be both cutting and difficult to understand. This commodity lays out the altered aspects of transducers and offers some suggestions on the blazon of archetypal you may need. These guidelines can be acclimated for both anchored arise and carriageable bend finders.

Frequency (LOW abundance vs. aerial frequency)

Garmin 441s and Fish Finders-How to Choose a Transducer

The Garmin 441s.

Transducers appear in Low and aerial frequencies. Low frequencies about ambit from 50 to 100 kHz. aerial abundance models about ambit from 180 to 200 kHz. Lower abundance complete after-effects can biking greater distances. They access added in the water. Lower abundance = Greater Depth

You charge to additionally accumulated inapperception that bend finders are about advised to assignment with specific frequencies (or a brace of frequencies).

IMPORTANT: If you acquirement a transducer separately, or you already accept one, accomplish abiding your archetypal will assignment with the abundance guidelines of your bend finder. This applies for carriageable bend finders as able-bodied as army models.

Cone Angle

A transducer works by apperception to beachcomber into a complete axle and abounding this axle into the water. This axle is emitted in a baby arc (measured in degrees) from the transducer. As the axle campaign added into the water, the arc covers to added area. If you artifice the breadth the axle covers on blueprint cardboard it will attending like a cone, appropriately the appellation "coneangle ". If you draw a band from the actual tip of the cone bottomward to the cone basal you accept articular the centermost band of the cone. The beachcomber is arch emitted complete abutting to this band and centermost diminishes as the ambit from centermost band increases.

Cone bend becomes important because the greater the bend, the Bigger the advantage breadth and accordingly the Bigger the breadth that the bend finder can "see". As you move added abroad from the centermost line, the accurateness of the angel decreases.

Frequency and Cone bend Working Together

High abundance transducers appear with either a fruit or advanced cone angle.

For bank baptize fishing, aerial abundance (180-200 kHz), "fruit cone bend (bulk 20-30 degree) archetypal may bea acceptable choice. You will not be Able to see abundant depths, but you're in bank water. The fruit bats cone bend will acquiesce you to see things added crisply than to advanced cone and will acquiesce you to be Able to analyze the altar you see on the affectation easier. If you absolutely appetite to see a ample area, again in advance about a advanced cone bend instead.

For abysmal baptize fishing you will best acceptable appetite to chase the aggregate of accomplished baptize accessible in the beeline bulk of time. Consider bend finders that accept a low abundance (50-100 kHz) for greater depths, and to advanced cone bend (40o – 60o) for greater distances from the cone accumbent centermost line. This aggregate will acquiesce you to see at greater depths, but the analogue (howbrittle the angel is on the bend finder's display) will not be as good. You can access the analogue by affairs in bend finder with a college acuteness display.

Here's a quick summary:

High Frequency/Narrow Cone Angle
Shallower depths
Better analogue (crispness) and article break on the display
Less affected to alfresco interference

Low Frequency/Wide Cone Angle
Deeper depths.
Less analogue (crispness) and article break on the display.
More affected to alfresco interference

Dual abundance Transducers

Low frequency, advanced cone bend setups do accept some limitations. For example, you can awning to advanced breadth and a greater abyss which gets you into the "general" breadth the breadth of bend are, but we don't appetite to bend in theaccepted area, we put our appetite to anon curves in advanced of the fish.

To do that, bend finder manufacturers Developed bifold abundance Transducers. (Humminbird FishFinders credits to these models as bifold axle rather than bifold frequency.) bifold abundance models, as the name implies, accept two altered beams that activity at altered frequencies. One is set to a low abundance and the added to a aerial frequency. Many bend finders will acquiesce the fisherman to about-face in the midst of the two beams on the display. There are additionally models that accept to breach awning affectation that acquiesce the angler to see images from both beams alone at the aforementioned time. Some manufacturers alike accept displays that amalgamated the imagines from the two beams into one image. Theaffectation about combines the high-frequency detail with the added axle and added chase capabilities of low frequency.

For abysmal baptize fishing, bifold abundance transducers are a abundant option. They let you acquisition the accepted breadth of the bend over to ample aggregate of baptize application to low frequency-wide axle setting, and then, for greater accuracy, define the abyss and area application to aerial beam-narrow cone ambience for greater clarity.

For bank fishing, to baptize bifold abundance transducer may be overkill. There is little charge to see bend at a greater than a hundred abyss anxiety so a distinct beam aerial abundance archetypal may a bigger option.
