How to understand what the fish finder is showing on the screen

While reading the data displayed on the screen of your fish finder can be quite a complicated tasks, there are some simple measures you can take so that you ease your learning curve. Depending on the complexity of the device you own, you’re likely to see info regarding the water depth, the temperature, as well as the reading speed. The water depth is important because it will allow you to understand what types of fish you might be targeting. This info can be found either on the upper right or the left corner of the screen. The water temperature will also be displayed, and that’s mostly due to the fact that various species like warmer or colder environments.

One of the hardest things to do when using a fish finder is reading the fish ID. While these days there are portable fish finders that allow you to understand the information shown on the screen a whole lot better, with older color or grayscale models, it’s way more difficult to discern. Depending on the unit you might have available, fish IDs can show up as arches or as designated icons. If the product you own utilizes the fish ID technology, you’ll be able to look at the screen and immediately find out where your target is located. Usually, the device will also let you know about other ecosystem components such as rocks, plants, and the likes. Whenever a fish icon shows up on the display, all you have to do is look at the water depth and approximate the location of the fish just so that you’re able to cast as efficiently as possible. From what we’ve gathered on the topic, fish finders that are equipped with the fish ID technology seem to be less reliable and accurate when compared to their arch counterparts.

By contrast, arch fish finders may raise a lot of technical difficulties to first-time users, but their signal seems to be more precise when compared to the one provided by the previously discussed alternative. If you have a rather basic model, you’ll probably be able to see data regarding plants and rocks, as well, but most of these will be reflected as lines instead of arches, as they’re considered stationary items. While using such a model may take a bit of time and effort, in the end it is well worth the while as you’ll be able to learn to discern between the species and sizes of fish you’ll encounter during your trip. A crucial detail to keep in mind at all times is that you ought to have enough patience to learn the works of the device you’ve purchased. In theory, all fish finders are easy to operate, but once you get your hands on an arch fish finder, you’ll see that it’s not a piece of cake.
