什么是CHIRP以及它是如何工作的

CHIRP st和s for “Compressed High Intensity Radar Pulse.” That’s a fancy way of saying it will show you those fish that st和ard sonars can’t. 这是怎么? A st和ard sonar sends one single frequency at a time. Since feedback from one single frequency is limited, the clarity 和 resolution of the sonar imagery will also be limited. CHIRP sends a continuous sweep of frequencies ranging from low to high, interpreting these frequencies individually upon their return. Since this continuous sweep provides CHIRP with a much wider range of information, a CHIRP sonar is able to create much clearer, 高分辨率图像.

清脆清澈的 华体会官网app+华体会官网app+ 2 displays makes it ideal for identifying fish, 定位结构, underst和 bottom consistency 和 most importantly, differentiating between targets 和 objects, so you have a strategic advantage over your target species.

识别鱼

华体会官网app应用

A fish will show up on your screen as an arch or straight line. If a fish swims through your sonar cone, it will return pulses from the edge of the cone, 中间和另一条边. The returns from the two edges of the cone have traveled slightly further than the returns from the middle. An arch is a fish that has come 和 gone into your sonar cone 和 a straight line is a fish right under the sonar.

识别鱼类时请记住:

  • Arches can vary in size 和 result from moving fish (or if your sonar is moving over them).
  •  Full arches appear if fish move through the full sonar cone.
  •  Half-arches or thick dashes appear if fish move partially through the cone.
  •  If your sonar 和 fish are both stationary, you will see a straight line.

确定鱼的大小

A common mistake anglers make is thinking that a long arch means a big fish. A long arch only means that a fish was in your sonar cone for a longer period of time.

The best indicator of fish size is the width of the fish arch. If an arch or line is thick 和 the color intense, then you’re marking a bigger fish.

学校的鱼

这取决于学校的类型, they can appear as groups of small arches or dense clusters with intense coloring.  

发现功能

寻找植被之类的特征, depressions 和 drop offs are essential for locating target species.

    植被

    A range of species, especially predators, use it as ambush points. 植被, weeds 和 brush piles will be dense 和 or sparse, vibrant in color 和 clearly defined from the bottom contour.

  • 经济萧条

    经济萧条

    Ideal for coarse fish, they like to peruse these areas searching for food. Small depressions will be very subtle in the bottom contour, but easy to identify.

  • 落点和积分

    另一种食肉鱼的最爱. Tips for locating drops offs 和 points (inclines/declines):

    • Set the depth alarm, especially when trolling, to alert you when you enter your chosen depth range.
    • Scan with a mid beam to get the clearest reading 和 to ensure you see any shelves or humps which will help you avoid “dead zones” (see how sonars work).
    • Create bathymetric maps in Boat Mode 和 Offshore GPS Mode. These maps will show drop offs 和 depth changes, making it easier to identify 和 return to hotspots.

理解底层的一致性

Being able to determine the hardness of a lake bottom 和 its consistency is a huge benefit to anglers. Your sonar display will show you how hard the object/bottom is by using color 和 brightness: The brighter the object on screen, 回报就越强, 物体越硬.

  • 底部的颜色
  • 底部厚度
  • 第二底返回
  • 底部的颜色

    底部的颜色

    白天模式显示, the intensity of the sonar return from a hard bottom will be shown in orange 和 a soft bottom will be purple. Day mode colors range from purple (softest) to red to orange to yellow (hardest).

  • 底部厚度

    底部厚度

    The thickness of the line representing the bottom is an indicator of bottom hardness, 线越粗, 底部越硬. But, be careful – sonar sensitivity can affect the thickness of the line. If you turn up the sonar sensitivity to 100%, 底线可能会显得更粗, 如果你把价格降至10%, 它会看起来更薄.

  • 第二底返回

    第二底返回

    Hard bottoms can send back very strong returns, which sometimes bounce down off the surface again. These will appear as a 2nd sonar return, running parallel underneath the line showing the bottom. If you see one of these, it is another indicator that the bottom is hard.

While not every object will be easy to recognize, you can always get clues from the shape 和 strength of the sonar return. Surprising objects can sometimes appear, our favorite was the “underwater UFO” that was actually pillars from an old bridge.
