Also it’s worth noting that the bottom structure images, as well as the topography images, come out strikingly life-like thanks the included contour shading feature.


The aforementioned features aside, there is a number of equally important points to understand if you are to learn the full capabilities of this unit:

-Transducer, which basically fulfills the function of antenna for the whole sonar unit. The transducer is responsible for the reception (from the transmitter) and subsequent conversion of electrical energy into a sound of certain frequency, which is then used to reveal the underwater areas. It is best to ensure that sonar unit frequency and the transducer frequency match each other. Of course, a transducer that is able to receive impulses for a high power transmitter and then change most of them into the sound energy would be the most suitable one.

-Display, its size, and resolution, which are all very important aspects for a fish-finder unit. And this is the reason of Lowrance HDS-7 model boasts a 480 by 640 pixels high resolution – it allows you an almost life-like perspective in regard to seeing fish or other objects located a large distance away from you. The 6.4 size of the screen also is large enough for looking at the images projected without any need to strain your eyes.

-Power, with a peak-to-peak output of 30000Watts and normal power output 250Watts. Such power levels allow the Lowrance HDS-7 to produce the minimal amount of noise even when functioning inside a boat which runs at high speeds while still keeping excellent performance and depth capability.

-Portability, an important feature for many users. Purchasing a device that offers high portability means that you will be able to move it easily between different places. As Lowrance HDS-7 is just this kind of fish finder, which makes it a personal favorite of many anglers. While using it, you can fix this device on the hull if necessary. This will provide better performance, and once its work is done, it can be dismantled back very easily.

-User-friendliness and the ease of use. In this regard, HDS-7 is a fish finder that is user-friendly enough, and can be operated effortlessly by an angler of just any skill level. This factor is reinforced by some of its features, for example, the inclusion of a keypad back-lighting. With this feature, even when operating under dim or non-existent light condition, the user will be able to operate this fish finder device without problems – the only requirement is an additional adjustment of keypad’s light settings.


Comparison to Other Fish Finder Models

We would like to compare the Lowrance HDS-7 to the model located on the opposite sides of the fish finder models spectrum. While NorCross HawkEye F33P can fit in the palm of your hand and has a compact design overall, the Lowrance HDS-7 is a lot more powerful (and much bigger, as expected). NorCross Hawkeye does not feature a pre-loaded cartography while HDS 7 is equipped with this ability. And while most of the light models out there lack in this department, there are a lot of other features included in this fish finder model by the Lowrance,
