Other important aspects include:

Transducer

The Mark-4 Combo Base doesn’t come with a transducer, however the upgraded version does. It functions on a skimmer transducer which consists of dual sonar beam which supports two different frequencies which are 83 by 200 kHz. The latter is highly sensitive with excellent target discrimination while in shallow waters. 83 kHz provides a broader cone angle for increased water coverage.

This makes this specific unit suitable for different conditions ranging from shallow to deep waters. This can either be fresh or salt water. In order to achieve maximum depth capability, the transducer must be installed correctly.

Display (Resolution and Size)

This is an important aspect of a fish finder. Larger screens are more suitable since they provide a large surface area which automatically translates to better view and clear images. Units with high resolution are highly effective due to their ability to focus and zoom into specific areas for detailed and enhanced images.

The Mark-4 combo has a screen measuring 4 inches and with a high resolution pixel of 320 by 240.

Power

Fish finders with high power outputs come highly recommended. The reason for this is because low output results in slow readings. This means that the details projected on the screen may be of an already passed section. The Mark-4 Combo has a point to point output of 2100 watts. This type of output involves the total output from a unit’s transmitter.

Fishing in shallow waters requires less power while highly powered units are suited for deeper waters.

Portable or fixed

Fixed units have transducers which are permanently fixed into a specific position which can either be on the stern, hull or trolling motor. Anglers who go on retreats or rent boats, portable devices such as the Lowrance Mark-4 Combo come highly recommended. This is due to their capability to perform in different situations. Their compact size allows for easy transportation.

Ease of use

In order to get maximum results from a fish finder it should have minimal complications in operating it. This makes the entire process much easier. Such devices including the Mark-4 Combo are easy to use and therefore suitable for anglers with different skill sets.

Our Verdict

The Lowrance Mark-4 Combo is a great little device with a price point to match. The features that are included with this fishfinder a second to none, and will suit any inexperienced and experienced anglers.

Normally we are not as emphatic with regards to recommendations however the Mark-4 Combo has certainly impressed us. The only criticism we have is with the manual and the lack of detail it provides. However in the scheme of things that is a very minor gripe.

Customers who have also purchased this particular model have raved on about it, and we would have to agree. We found no faults when testing it out on the water.
