Best Fishing Barometers Buying Guide

Anglers are aware that there are several elements that influence the success rate of a fishing trip. Some of the most important ones are water temperature, the light level, the tide or moon phase.

Still, many times, a factor of utmost importance is undermined – namely the barometric pressure. While it is true that one cannot predict it, a certain device can help – namely a fishing barometer.

How Do Fishing Barometers Work?

To start with, we’ll clarify what a fishing barometer does, how it works and how it can help your fishing sessions. Most barometers feature a closed tube, which stands upside down in a bath of mercury. Mercury is preferred over water, primarily because water is less dense and, hence, less heavy.

Barometric pressure – also referred to as atmospheric or air pressure – represents the air of the weight, which presses down upon everything, fish and anglers included.

Even though humans cannot detect changes in barometric pressure, fish can. Truth be told, fish are in tune with their environment, far more than anglers realize. That is primarily due to their pressure-sensing systems – such as the lateral line. This allows them to grasp even the slightest atmospheric change.

The pressure exercised on the water’s surface affects the fish through the air bladder. Therefore, when the pressure is high (1018hPa or higher), this applies more pressure on the air bladder. This means that the fish are relaxed and comfortable – hence, their behavior is normal.

On the other side, when the pressure is low (1014hPa or less), the pressure is reduced. This causes the expansion of the air bladder, placing pressure on the fish’s stomachs. Evidently, this translates into a low rate of fishing success.

Key Features to Consider

  • Build Quality

Assessing the built quality of the barometer is important. Otherwise, you’ll be buying a product that will need replacement, sooner or later. Therefore, make sure you analyze the construction and craftsmanship of the unit before buying it.

  • Accuracy

Another aspect of critical significance is, evidently, a barometer’s accuracy. There’s no use in investing in a product whose accuracy is impaired. Make sure you check customer and expert reviews beforehand to determine if a barometer is, indeed, helpful and accurate.

  • Budget

As a rule of thumb, we all have a budget whenever we’re in the market for something important. That being said, you should confirm your budget, and the characteristics you’re looking for in a fishing barometer. After doing that, you should get the one that has the best price-quality ratio for your budget.

It indicates the barometric pressure, the humidity and the temperature outside. That is to say, you get the most important information regarding the weather.

For the most part, installing the barometer is quite easy – you’ll need AAA batteries in this respect. The good thing is that the weather sensors are already calibrated for accuracy.

The design of the unit is user-friendly as well, considering that you can assess the information from a considerable distance – of up to 6 feet. What is more, you may easily read the barometer with sunglasses on.

You can also use it at nighttime, due to the backlit option provided by the manufacturer. Moving on, the display includes information on the barometric pressure, as well as the weather forecast.
