Fishfinder and Transducer Functions

fishing divider

This castable fish finder lets you scan to a top depth of 750 feet or 228 meters in saltwater. In freshwater, it’s limited to 1,600 feet or 487 meters. But, this is possible only if you possess a transducer capable of 50 kHz. The transducer that comes out of the box has a top depth of about 800 feet or 244 meters.

The Garmin striker 4 fish finder from Garmin comes equipped from the factory with the 010-10249-20 transducer and uses a 4-pin connector. This is 77/200 kHz capable and uses two cone-shaped beams. One 45° beam for 77 kHz, and one 15° beam for 200 kHz. If you need to search through bigger depths, you can use the control unit with a 50/200 kHz transducer. That’s because it is capable of 50/77/200 kHz. You should also know that the control unit is capable of only using High and Mid CHIRP.

How does a fish finder work

This device  2D  on offers a lot of useful functions. Among these, there are the A-Scope, UltraScroll, Flasher, Auto Gain, Fish Symbol ID, and Split-Zoom, including different alarms. For people who aren’t familiar with these functions, here’s a quick explanation of some.

Powerful CHIRP sonar provides the Garmin Striker 4 with quality images. In other words, a clearer picture means targets that are better defined. It also means a better view of the bottom, as well as less clutter on the screen. Besides that, CHIRP has an incredible separation of targets. With CHIRP a firmly packed school of fish won’t appear as a single, larger target. This can be a problem with conventional sonar units.

The Fish Symbol ID function processes the sonar returns in different ways and adds different fish icons to them. Besides that, this device shows the depth of each target fish. It’s easy to see how useful this can be to every owner of the Striker 4.

The Flasher mode is a depth scale in circular form. It also provides information on targets found by the sonar beams. The Flasher’s inner rings show depth, and the flashing segments on the outer rings show different sonar returns measured in strength. This function comes in handy when ice fishing or fishing from a stationary position.

The Auto Gain function gives users the chance to let the unit filter out unwanted noise without manual adjustment.

The A-Scope is also a flasher function. The difference is that it provides information in a vertical layout about the most recent returns from the sonar.

With Ultrascroll, you can scan while moving at high speeds. It enables faster scrolling of the sonar data. But, if you’re going over 40 Mph, the image quality will suffer. outdoor fun

There’re a couple of things left to mention in this section in regards to the transducer mounts. The Garmin Striker 4 comes with a trolling motor mount as well as a transom one. There’s 20 feet or 6 meters of cable in the box. Also, there’s a sensor for temperature integration.
