Priced around $1250, it can be said that the Lowrance HDS 7 Gen 3 is on the more expensive side of the pricing scale. However, if you take into consideration all of the features that come along with this unit, you can easily say that it is worth every penny spent. This unit is a complete setup, equipped with transducers and other items necessary in order for you to possibly maximize your time for fishing on the water. It uses both 83/200 and StructureScan transducers which provides an all-in-one solution for any fisherman who is interested with having features such as DownScan, Traditional Sonar, and SideScan, all in a single box. It is also possible to overlay images from DownScan to the Broadband Sonar, giving you great target separation and detail and providing you with the best possible fish view and structure, both to the side and below your boat. On top of the most advanced fish finding capabilities of the Lowrance HDS 7 Gen 3, it can also provide you with easy-to-operate features, thanks to its touch screen display. You may also use the keypad if you want to. It has enhanced the response of this unit by adding a much faster interface in order to drive the newest in electronics technology by turning the fastest HDS ever created.


The good thing about competition is that you have different options to choose from, allowing you to consider the best one that will suit your preference as an angler. As a matter of fact, there are also other brands that are currently offering similar products on the market. One of those products is the Humminbird 998c fish finder. It is considered a good option because of its advanced features, which are unique and user friendly. It uses new technology to help anglers find the best fishing locations. It is also functional as it is not just for chart plotting, but for other tracking services as well.

However, if you are loyal to the Lowrance brand, you can also choose another fish finder under this manufacturer. One good option is the Lowrance X4 Pro, which has the capability to cover a wider area, thus allowing you to become more successful on your fishing trip. However, if you compare all of the features of the Lowrance HDS 7 to the others, it can be said that the HDS 7 is the winner in terms of advanced features. True, it may be more expensive, but this can turn out to be the best investment that you can ever make.
