Types of Fish Finder
Before you purchase a fish finder, you must first consider learning about it. This way, you will be able to understand how to use it effectively. Be reminded that the product has a variety of types. To give you ideas regarding this, given below are the top categories of a fish finder:
Standard Sonar. You can consider this as the common type of fish finder. It has been present since the ‘80s. However, it became more popular during the ‘90s. The equipment is recognized for using one to two beams. It provides results on an LCD Screen.
At present, basic fish finders are popular for using hotter colors, such as yellow, green, and red. You may use the equipment for various purposes. Its 200-kHz beam feature became the norm among fish finders, particularly because of its versatility.If you often fish in a bay, lake, ocean, or river, you will not have any issue using this type of fish finder.
However, the standard sonar also has its disadvantages. According to reports, its performance is still subpar. Also, the levels of detail given by the tool are as not as advanced compared to the newer types of fish finders.
Scanner or Imager. This is another type of fish finder that commonly uses a 455/ 800 kHz frequency. Its main purpose is to take an image underwater, which is similar to what MRI does. What makes this product more interesting is that it can be bought for only a few hundred dollars.Still, it is not as perfect as it seems since it is known to suffer from a loss of range. It is also rare for the equipment to find the bottom of the sea in a few hundred feet. Moreover, since it makes use of high-frequency beams, not all aquatic species are identified.
Side-Scanning Fish Finder. You can consider it as the predecessor of the scanner or imager. It perfects the utilization of the high-frequency beams. This is why it still uses the 455/ 800 kHz range, which the scanner or imager is known for.
Nonetheless, it requires you to practice when dealing with palette or range. To make the most of this type of fish finder, your screen must have a size of eight inches at the minimum.
You can consider this fish finder most useful in identifying structure. Still, it is not declared 100 percent efficient for fish tracking. Moreover, it is actually expensive than the two first types of fish finder.
What to Look For When Buying
There are important factors that you must consider when purchasing a portable fish finder. Similar to buying standard equipment, you must focus on the overall quality of the item instead of concentrating on the price point solely.
To help you with the wise selection of a product to purchase, given below are the attributes that you must consider before finally deciding on a fish finder:
Frequency. You must remember that a higher frequency will provide more details on the screen of your fish finder. This is due to the fact that there are more sonar waves being delivered and obtained by the transducer of the equipment. If you fish in shallow water, high frequencies are very reliable.
You can find the best portable fish finder by considering more than 400 kHz frequencies. Take note that if you read at 50 kHz, you will get nothing but a fuzzy water bed. If you try looking at the same area at 200 kHz, you will notice that the details will become sharper, giving you an idea of the presence of plants or fish.
Power. It is also important to take regard of a fish finder’s power. This factor is necessary for selecting the best portable fish finder since the greater the power is, the faster your desired details will be displayed. Moreover, your readings will be deeper as well. Take note that if you use a tool with a lower wattage, you will get results slower. You may only use it when fishing in shallow water.
Logically, low power will lead to slow sonar wave transmission. As a rule of thumb, every 100 watts of power at 50 kHz will provide you with up to a 400-foot reading. Alternatively, every 100 watts of power at 200 kHz will give you up to 100-foot result.
Screen Resolution. In order to find out if the screen resolution of your portable fish finder is reliable, you should find out if it passes the standard of at least 240 by 160 pixels. The said measurement is actually the minimum. If you are seeking for crisper and sharper images, you should consider a higher resolution alternative.
In case your main purpose is to buy a main unit, you should always go for the highest resolution you can afford. However, if you are simply searching for the best portable fish finder as a backup, then you can settle with a model that has a small screen.
Tips for Using a Portable Fish Finder
If you want to utilize your chosen portable fish finder, you must consider checking out the recommendations of fishing experts. Take note that although your equipment is packed with features, its overall quality will also rely on how it is operated.
To help you with the usage of a portable fish finder, given below are suggestions you may take note of:
Keep It Simple. According to fishermen, you should keep everything basic when it comes to configuring the settings of your portable fish finder. In other words, you need to start by shutting off all the factory set filters.
Take note that the filters integrated into the fish finder will only provide your assumptions. Without these, you can prevent false sonar returns. You will be more knowledgeable if you can distinguish the details from the graph by yourself.
You must remember that there is no correct setting for your fish finder. There will always be lots of rights and wrongs. You simply have to find out what works for you and stick with it.
Learn How to Find Fish. You also have to consider the vital signs when perceiving huge species, schools of fish, and predators in the water. If you can recognize these important indicators, you will be able to use the portable fish finder more effectively.
Never Forget the Weather. Using the best portable fish finder does not guarantee that you will catch lots of fish easily. Instead, you should also consider the standard procedures before fishing, such as checking out the weather beforehand.
Be reminded that fish will always be dependent on the climate. During warm weather, you can anticipate more catches. However, in cold days, you can expect the aquatic species to stay in their normal spots under the water.
Find Out the Sensitivity Tune of the Equipment. You must know that there is a single sensitivity tune you can use to search and hit the fish jackpot. Instead of utilizing a fish finder’s automatic mode, you should adjust the feature depending on how precise the information is being given about the fish.You can determine the level of information provided by the device every time you check the fish finder’s curves.
Utilize a Variety of Baits. Do not stick with a single type of bait. There are times that some species can be choosy. Their pickiness may also be affected by the current weather.
With the helpful facts above, you will find it easier to select the most reliable and portable fish finder. Be reminded that when selecting a brand to purchase, you should not only focus on the attributes of the products. Instead, you should also consider your personal preferences.
