Fish rulers are used by anglers to measure the fish they catch. It is important that you choose the proper fish ruler. This is to make sure the fish that does not meet the legal length is freed.

Keeping a fish that is shorter than the standard length might result in getting a ticket and cost you a fine. Stretching and folding tape fish rulers that are made of plastics have tendencies to shrink when exposed to high temperatures. As a result, it could give you an erroneous measurement.

Like any other purchase, buying a fish ruler has many considerations. It is always important to choose the right fishing ruler for you. Nowadays, there are countless fish rulers on the market and finding the best one that will suit your style and requirement is never easy.

Criteria Used for Evaluation

Durability

In choosing the best fish ruler, the most crucial factor to pay close attention to is durability, quality and accuracy.

A good quality fish ruler will not only produce accurate measurements but also save you from getting penalized. For example, you want to ensure that the ruler along with its components is made of superior materials that will not break, peel off, or disintegrate while you are using it to stay legible.

Making sure the ruler offers a permanent and attractive alternative to even stickers is important for legibility and its lifespan. Look out for features such as laser-etched numbers that will not fade or break down to help with the durability of the fish ruler.

Accuracy

In order to avoid getting penalized, a reliable and accurate fish ruler is needed.

While fishing is a good and a rewarding hobby or recreation, there are certain rules that must be strictly followed. The fish ruler plays a vital part in one of these regulations.

It is vital that you choose the proper fish ruler to make sure that fish that does not meet the legal length should be freed. In other words, the fish ruler is crucial in making sure that you do not keep undersized fish.

Keeping a fish that is shorter than the standard length might result in getting a ticket and cost you a fine. Stretching and folding tape fish rulers that are made of plastics have tendencies to shrink when exposed to high temperatures. As a result, it could give you an erroneous measurement.

Size

There are different options when it comes to the size of your fish ruler model.

Many different rulers come in 2 options; one is regularly 1x20-inch ruler and the other is a 1 1/4 x 56-inches ruler. Depending on the size of fish you are looking to catch, you can know which ruler to bring with you. Keep in mind both ruler's measurements read from left to right so they are all similar in design.

On the ruler, the measurements have big markings that measure 1/8-inches for you to be able to read easier. So make sure you know which type of fish you are going to be fishing for to bring the proper size and measurements.

Advanced Features

Many of the fish ruler models on our list have very specific features that make them unique.

Before making a decision on which fish ruler to get, you should be asking yourself questions such as does it have good markings that can be read even at a particular distance? Is it easy to use? Is it ergonomically designed? What could you benefit from it if you use it?

There are many questions to ask yourself. Keep a lookout for fishing rulers that have specific features such as the ability to fold into half or even its ability to float on water. So you will not have to worry about finding your fish ruler the next time it slips and jumps to the water.
