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 depend on the water’s temperature. So, if you have a fishing thermometer at your disposal, you can find the best fishing spots.
Fish tend to match their body temperature to that of the water. Hence, when the temperature of the water dips, the fish’s metabolism slows down, reducing 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 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 with ideal fish conditions.

Best Fishing Thermometer Buying Guide
A fishing thermometer, as stated earlier, allows you to check the water temperature to 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 the 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 with just the right water temperature.
Ease of Use
Any fishing thermometer that you choose must be easy to use. Anglers often go for digital thermometers as they feel they are great investments. However, you may need to focus on the technicalities of the thermometer and understand its 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 must dangle the thermometer for a few minutes in the water to determine 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.
The durability of the Thermometer
It is best to have a thermometer housed in a metal casing with thick glass. That way, it can take rough use and wear and tear without breaking. Most metal fishing thermometers are extremely durable. Make sure the metal is high-quality and rust-proof, as you will be immersing the thermometer in 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 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 essential features you should look 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.

To use a fishing thermometer, lower it into the water you’re fishing in until it reaches the desired depth, usually around the bottom of the thermometer. Read the temperature and remove the thermometer from the water.
