Fishing Thermometer by FishPond


While many anglers do not consider fishing thermometers essential for success, you can improve your chances of a good catch if you are armed with the best fishing thermometer. There is a scientific reason behind it. The feeding patterns of different fish species are dependent on the temperature of the water. So, if you have a fishing thermometer at your disposal, you will be able to find out the best fishing spots.

Best Fishing Thermometers

Fish tend to match their body temperature to that of the water. Hence, when the temperature of the water dips, fish’s metabolism slows down and this reduces the need for food. As a result, this can have a negative impact on your fishing opportunities.

On the other hand, if the temperature of the water soars, oxygen content depletes. This causes the fish to become lethargic and they do not eat much.

A fishing thermometer helps you find the optimal water temperature and in doing so, ensures your fishing success. With the help of the thermometer, you can ensure that the water is neither too hot nor too cold and stick to spots that have the ideal conditions for fish.

Check out our unbiased reviews of the top 6 fishing thermometers. We have based our list on personal experience and user comments and reviews to ensure you get an honest idea about the fishing thermometers that are the best. Also, you will get an insight on how to buy the best fishing thermometer so that you can make an informed choice.

Best Fishing Thermometer Buying Guide

A fishing thermometer, as stated earlier, allows you to check the water temperature so that you can find the best fishing spots. However, do not opt for a fishing thermometer blindly. You need a well-built model that ensures accurate readings and can take the wear and tear of fishing.

Here are a few factors that you need to check for when you are looking to buy the best fishing thermometer.

Purpose of the Thermometer

It is prudent to remember that water temperature keeps rising with the sun. Hence, fish will not feed when the water is too warm. This will have an adverse effect on your fishing performance. So, opt for a fishing thermometer that can gauge the temperature of the water any time of the day to help you locate fishing spots that have just the right water temperature.

Ease of Use

Any fishing thermometer that you choose must be easy to use. Many times, anglers go for digital thermometers as they feel it is a great investment. However, you may need to focus on the technicalities of the thermometer and understand the different features before you can use it to your advantage. This can make digital thermometers more of a nuisance than a help. Also, digital thermometers use batteries and you will have to keep replacing them.

Furthermore, you cannot submerge digital fishing thermometers completely in the water as they will get ruined. That is why it is best to opt for a traditional thermometer that allows you to get accurate readings and does not require batteries. Typically, you just have to dangle the thermometer for a few minutes in the water to figure out the temperature.

Accuracy of the Thermometer

It goes without saying that the best fishing thermometer is one that offers you accurate readings always. Since you will not be able to test the fishing thermometer, it is best to read reviews from other buyers to find out how accurate the thermometer is. Most thermometers allow you to measure the temperature ranging from 20 to 120 deg Fahrenheit and they take anywhere from 5 to 7 minutes to throw up a reading.

Durability of the Thermometer

It is best to have a thermometer that is housed in a metal casing and has thick glass. That way, it can take rough use and wear and tear without breaking. Most metal fishing thermometers are extremely durable. Make sure that the metal is high-quality and rust-proof as you will be immersing the thermometer into the water.

Fishing Thermometer Design

While this is not an essential feature, you should ensure that the thermometer design is such that you can read the marking with ease. Some have tiny markings, making it difficult for people to gauge the temperature of the water. Also, a well-designed thermometer is pleasing to the eyes and if it is brightly colored, you will locate it easily in your gear. 

Attachment Feature

Fishing thermometers are small and it is very easy to lose them in the water. That is why you should ensure that any fishing thermometer you choose has an attachment feature that lets you connect the thermometer to a lanyard or your fishing rod so that there is no risk of losing it in water or while traveling to your fishing spot.

Size of the Fishing Thermometer

The last thing you need is a heavy and big thermometer. The best fishing thermometer is compact and small enough to carry in your pocket or your tackle box. So, it should not be more than a few inches in length. Of course, this can make the markings difficult to read but if it is designed properly, you should not face a problem.

These are the most essential features that you should be looking at when you want to buy the best fishing thermometer. If you follow these buying tips, you should be able to shortlist a few thermometers and then cull the list further until you choose one.

Final Verdict

These are the five best fishing thermometers. Out of these, we feel that the thermometer by Scout-a-Bout is the best. It meets all the requirements listed in the buying guide and it also has unique features that make it the best fishing thermometer.

It is just 4.25 inches in length, allowing you to carry it in your pocket. The hard resin exterior makes the thermometer durable and long-lasting. It ensures accurate readings and is specifically designed for bass fishing. However, you can use it for other fish species as well. We also feel that the fishing thermometer from Scout-a-Bout is the best as it is an analog thermometer and hence, does not require batteries. You can read the water temperature in Celsius and Fahrenheit and the Liquid Crystal Technology used for the readings make it extremely accurate and precise.
