Fish finders from the manufacturer Fish Finder are in great demand. They are inexpensive and portable. They are classified as amateur models with a modest set of functions. For example, the Fishfinder 140 sonar wiring diagram is designed in such a way that it recognizes objects at great depths, has a two-beam emitter and a peak power of 800 watts.
What is it
Fishfinder sonar is a measuring device that uses sound to study the topography and bottom structure. It discovers underwater objects and fish. In working condition, it continuously monitors the pond, monitors changes in the bottom topography, receives information from the sensor and sends information by displaying it on the screen. Its main task is to detect fish and display the image. Experienced users of this device are able to recognize prey even by indirect signs.
Echo sounders are equipped with a built-in GPS navigator, which makes it possible to use maps for navigation and save fish location information with maximum accuracy. The unit (sensor) sends pulses of a certain frequency. They are reflected from various objects, including the bottom. The sensor collects information about fish size, abundance, topography, and more. After processing the information by the processor, a graphic image is displayed.
How to use
What is the principle of operation of the Fishfinder sonar? Instructions for use help to understand how it functions. The echo sounder has the following technical characteristics and functionality:
- simulation mode;
- backlit display, screen sizes 38x38 mm;
- the ability to measure depths from 0.7 to 100 meters;
- battery saving mode;
- waterproof case;
- charge indicator;
- display of the bottom structure;
- the ability to select the unit of measure (meter, foot);
- mode of reduced or increased sensitivity;
- sound signal;
- fish depth detection scale.
The device has a scanning angle of 40 degrees, operates at temperatures from -20 to +70 degrees. It consists of four main elements: a display, a radiator, a dacha and a converter. Fishfinder fish finder is a modern device that receives, displays various information about the status of the water column and the number of fish in the pond. It is controlled by several buttons and menus on the display.
On the screen there is a control panel, information about the battery status, water temperature, fish speed, depth of the reservoir. The menu allows you to control the echo sounder, change the settings for scaling, sensitivity. For example, a scale is needed to view certain sections of the water column. With the help of "Scale" objects are increased, and the "Scale of Depth" allows you to set and view the desired sections of the reservoir on the display. The screen displays the frequency, fish symbols, bottom topography, temperature, obstacles. All information is sketchy, so you should not expect more from the budget model of the echo sounder. By changing the settings, you can control the device.
Features
Fishfinder sonar is wireless and solves many problems of the angler. It is ideal for fishing in wet, cold, frosty weather, from a boat or shore. The device measures the depth of the reservoir and finds production without drilling a hole in winter. The sounder operates in all weather conditions day and night. Finds without difficulty the place of accumulation of fish, is able to completely replace the marker rod. Many Fish Finder models are compact, ergonomic, and fit in your pocket with ease.
The Fishfinder 140 sonar has a four-inch backlit screen and Garmin's unique fish-finding technology. It consists of a two-beam emitter that functions perfectly at shallow depths. The viewing angle of the echo sounder is wide, the screen is contrasting. Ultrascoll function instantly updates the picture. In addition, when changing the range, an automatic indication occurs, the changed settings are saved. The device has a function for determining the properties of the bottom, manual and automatic zoom, alarm, battery indicator.
Prices
How much does a fish finder cost? For example, Fishfinder device models fall into the budget category. The manufacturer produces compact devices with a monochrome screen at an affordable price. The minimum cost is 1800 rubles. On average, small echo sounders with a black and white display cost up to three thousand rubles. There are models and more expensive. The choice of the echo sounder depends on the material capabilities of the fisherman and personal preferences.
Reviews
Which is the best fish finder? Fishfinder (reviews confirm this) is an excellent manufacturer producing inexpensive models of functional echo sounders. A large selection of budget and expensive devices with black and white and color displays are brand advantages. According to users, such echo sounders have huge advantages: they are portable, convenient, ergonomic, functional, inexpensive. Beautiful design, good equipment, maximum accuracy - what else is needed for successful fishing? Of the shortcomings, it is noted: sometimes it malfunctions, and if the battery runs down, the device gives out distorted information, shows the inaccurate location of the fish.
