How to Choose the best fish finder gps combo?

You have probably found yourself in a difficult situation when trying to choose a fish finder that best suits your needs. Here are some of the factors that you can consider when selecting a Fish finder that suits your needs.

1. Transducer

The transducer is the primary component of the fish locator, and it works by sending sound waves into the water and acquiring the details of objects located in the water. The most important feature when choosing a transducer is the cone angle. The bigger the degree on the cone the more the coverage of the underwater. However, wider beams lose strength quickly and therefore cannot go as deep as the narrow cone. Fortunately, both capabilities can be found in the dual beam or multiple beam type of transducers.

2. Display Size, Resolution, and Color

Displays with more pixels are clearer and more expensive. A bigger screen size will similarly provide a better and more unobstructed view that will enable you to differentiate the data. Additionally, colored displays provide more details, easier viewing of underwater and enhanced usability in bright light but black and white screens are cheaper.

3. Power

The power of the Fish Finder is also an important feature to consider when choosing one. A fish finder with more watts is more efficient, exhibit better speed when displaying readings and is suited for deep waters.

4. Frequency

The amount of detail displayed on the screen is usually determined by the frequency of the transducer. Therefore a higher rate will provide you more information than a lower frequency.

5. Portability

Depending on your needs, you may go for a self-contained portable fish finder or a fixed one that needs to be attached to the boat.

6. Inbuilt GPS

Some Fish Finders have an inbuilt GPS while others don’t have. You should, therefore, check whether the Fish Finder you want to buy has an inbuilt GPS or not. A GPS is vital in calculating your exact position and an important feature of fishing as well. Therefore it is more convenient, economical and space saving to have it in one unit.

To Summarize

Having gone through the factors to consider when choosing a Fish Finder and the top ten reviews of Fish finders, I would select Lowrence HDS-9 GEN3 as one of the the best overall fish finder for its features and performance. It has a clear 9 inches large screen that enables viewing of more details and can be vertically and horizontally zoomed to differentiate objects beneath.

All these features and technology involved are offered at a good price. IMO this product has taken care of almost all the considerations including your pocket as a fisherman or woman.
