  • Page 2: Introduction

    INTRODUCTION History of fishing amounts to thousands of years. However, in reality each time the fisherman faces the same challenges: how to find the fish and make it grab the bait. The sonar cannot make the fish grab the bite, but it is able to solve the problem of finding this fish. You will never catch the fish there where there is not any –...

  • Page 5: Sensor-Converter And Battery Compartment

    The electronic unit represents the structural design with two control buttons, transparent window and tightly closed cable not less than two meters long. The level of leak resistance is compliant with IP 67 standards. Sensor-converter and battery compartment The sensor-converter works simultaneously as an acoustic wave emitter as a receiver (microphone) of echo-signal objects reflected from the bottom.
  • Page 6 In the body of the device there are four fastening openings located along the body angles. They are designated for fastening the cord and for installation the special furniture on the device to fasten the sonar to the leg or the sleeve. The furniture is not included in the set. There is a special bracket for the sensor in the delivery set.

After the sensor contacts the water the appearance of micro-bubbles on its sensible surface is possible which can strongly dissipate registering signals and thus reduce sensibility and mispresent the true picture. It is required to remove the bubbles plunging the sensor for several times or rub the sensor surface with your fingers after plunging it into the water.

  • Page 13: Sonar Option Menu

    SONAR OPTION MENU MENU serves to control operation modes and fine adjustment of the sonar. Input from the operation mode is performed by double pushing the right button. The basic MENU consists of four points. Designation of these MENU points if highlighted below. MODES SCALE OF DEPTH NOISE AND OBJECT FILTER...

It is more complicated for perception than the fish signs, however it provides more additional data for an experienced user. In RTS window one can take notice of the echo-signals located in the beam zone. example, vertically falling load (feedbox) will be clearly seen in RTS, but it will not be detected as the fish and we will not see the fish contour on the screen.
  • Page 16 fish contour. It is known that the sonar can see the fish first of all because of its air-bladder. That is why its size will affect the fish contour size in the first run. For the same reason in summer when moving the bubbles with gases on the algae may “appear”...
  • Page 17 In mode Pro or reflecting raw data (without processing) the whole screen is devoted for reflection of unprocessed data. The sonar does not attempt to identify the fish, and it only shows all reflected signals that it was able to detect. This mode is the most useful for experienced fishermen as it allows to detect thermo- clines, algae and other objects and better understanding of the water thickness structure.
  • Page 18 the sonar Praktik ER-6Pro2 to watch the objects in the real time scale mode. The screen is divided in two equal parts in the “Flasher” mode. “History window” is on the left where unprocessed signals that have been surveyed by the sonar are reflected (as in “Pro” mode). The Flasher occupies the right half: with each update of the screen (4 times a second), it draws wide marks of all detected objects including the bottom (it, different from other objects, will occupy the whole width of the right part of the screen, and not the quarter of the width).

  • Page 19: Fleet Water

    probing and processing considerably differ from the depth measurement in other sonar modes. Depth measurement for the difficult condition is performed especially precisely, for example, fleet water and grown-over reservoirs may be referred to these conditions. None of the fish and any other date on the water depth is displayed.

  • Page 20: Demo

    Fleet water mode is intended for use in shallow water (2 meters or less). In this mode the sonar provides the sounding of water by acoustic signals of very low power. It allows avoiding re- reflected signals and receiving more reliable and understandable information on the display. The sensitivity adjustment (with the right button) will also operate.

    with electronic or the sensor п). We recommend to carry out Auto-calibration or turn to the service center for consultations or performance restoration of the device to operational characteristics. General recommendations for correct operation with the DEMO mode:  The sensor should be motionless and the sensitive area of sensor should be parallel to the floor surface.

    bottom or constantly use the scale set manually through MENU. Besides, the near-bottom reflection mode in the increased mode (scale-up) – so-called “zoom”. Auto-scaling mode (the sonar starts working after changing the battery) enables the device to select itself an appropriate scale to locate the bottom line approximately on the level of one third from the bottom part of the screen.
  • Page 23 When ZOOM is on, the screen if divided with the vertical line into two equal parts (see the picture). The near bottom area will be reflected in the right part область and the ordinary processed or raw data (depending on the selected reflection mode) along the whole route from the surface to the bottom will be shown in the left part.

Typical example of ZOOM operation is shown on the picture. «ZOOM» in “flasher” mode somehow differs from “zoom” in other reflection modes (see the picture): the ordinary “flasher” window will be located in the left part of the screen, and the right part shows only the near bottom area of the set size (as in ordinary “ZOOM”), however, with the signals marks all over the window...

    ADJUSTMENTS Fine adjustment of the sonar can be performed in this MENU point for the specific conditions and tasks. The list of adjustments and recommendations on their application is given below.

If you set the dead zone larger than the depth value in this location, the sonar will show the depth two times more than what it is actually (for example: dead zone - 1.5 meters, and the depth of the reservoir - 1.4 meters;...
  • Page 28 amplification refers to the last ones: with its increase more weak signal may appear which is not always justified as large amount of information may prevent right assessment of the bottom picture and the route. If the set amplification is insufficient for the bottom detection the device will show zeros or the depth figures will be changed chaotically.

This manual provides operation time of the sonar from different sources of power in AA format on the last page.  Fish sounding and identification mode operated quite sufficiently only with the immovable sensor, sensitive surface of which is located strictly in parallel to the water surface. When using the sonar while moving it can provide more quantity of false response or miss real fish.

In summer, especially when moving it also allows to see many details, however constant depth change of the bottom complicates analysis of the receiving information.
  • Page 31 the sonar. If the figure reading is stable the bottom is likely even and uniform. The bigger the density figure with constant depth is the better the bottom has the reflecting capacity.  Auto-scaling mode is preferable for use in motion, as it excludes necessity of manual interference when the bottom line goes out of the screen limits.

     To return to factory settings you need to reset the device (RESET). The reset can be made only when the device is switched off. For that you need to switch off the device by pressing the right button or take out the battery and to put it back into the battery compartment. Then press and hold the left button, and then not releasing the left button, press the right button for 1-2 seconds.
