Key features of the Raymarine AXIOM 7 that one can’t miss

The Raymarine AXIOM 7 is one of the best, technologically equipped fishing Chartplotter that have ever been invented. It has won numerous awards for its design and versatility, notably the MIBS Innovation award in 2017. Here are some important features of this Chartplotter  that makes it stand apart from the rest:


With a 7 inch, 800×400 WVGA, and 1200 nits brightness, it ranks high on display. As the screen is wider than in most models, it becomes easy for the user to view the water underneath and cast his Chartplotter accordingly.

It has a high resolution, which leads to enhanced sharpness, hence the user can get a clear picture of the water body in which he is fishing, ascertain the movements of the fish and catch them accordingly. 

Raymarine AXIOM 7 Display

The screen can also be viewed in the dark because of its vibrant backlit display. It also has accurate side imaging features, which help us distinguish one fish from the others based on their color and also offers a clear contrast between the fish and water. We can also pin the apps that we use the most on our screen, thereby paving the way for easy access. 


With a versatile and compact design, the Raymarine AXIOM 7 is such a joy to use, for both novice and experienced anglers. The dimensions are average, it weighs less and the rod is easy to wield.

It has a high waterproof rating and a decent 4 GB memory, which can be supplemented by external SD cards placed in the appropriate slots on the machine. It draws 12V DC from its battery. It has a built-in GNSS receiver and SONAR. 

Raymarine AXIOM 7 design

In the case of GPS navigation, one must use an external accessory. External SONARS can also be added, to improve real-time user experience. The design is also expandable, supporting important accessories like CHIRP SONAR, FLIR thermal cameras, audio integration, instruments, and cameras. It also has an efficient embedded weather sensor and supports digital switching through Empiribus.


With significant built-in features and a plethora of accessories that can be added, the design of Raymarine AXIOM 7 does not complicate and reduce its performance. Its efficient imaging cameras can capture and give crystal clear images of fish and even underwater plants throughout the depth of the water body, from the floor to the surface on land. 

Raymarine AXIOM 7 Performance

With GRIB vie taking care of weather sensing, it can be used under all weather because of its flexible, waterproof design. It can be operated over a wide range of temperatures and can function very well between -25 to +55 degrees Celsius, making it ideal for summer, winter, spring, autumn, and monsoon use.

It is also equipped with Autopilot so that even people who have never fished in their lives and don’t have an opportunity to learn fishing can use this.  


Raymarine AXIOM 7 is compatible with Lighthouse 3, which is the most versatile and premium marine electronics software (developed by Raymarine). Lighthouse 3, working in tandem with a quad-core processor, lets us add and efficiently use accessories like Bluetooth for audio integration and add-ons for remote control operations.


Like most Raymarine products, the Raymarine AXIOM 7 also has a versatile and robust networking system, featuring a huge variety of networking options, including Wi-Fi and Bluetooth.

It has an in-built NMEA port but a suitable, machine-specific adapter is required to connect to the NMEA 2000. It can also be connected to Ethernet through the built-in Ethernet port, without requiring any external connecting device. 

It requires a 400mm DeviceNet female adapter cable, to connect with Sea Talk. It requires a 0.5A charging external storage device or accessory, to connect with the built-in USB port. It also has a microSD card slot that can be used for networking and connecting with multiple other devices and accessories.


It is equipped with Navionics Nav+ charts, which are suitable for navigation only in the US and Canada. But it is also compatible for use in central and Latin American countries, owing to the Lighthouse 3 software update, vector charts, and C-MAP, which can also accommodate future Lighthouse 3 updates.

When it comes to GPS, AXIOM 7 has a precise and accurate 10Hz GLONASS/GPS module. It has enhanced satellite acquisition and improved sensing mechanisms. If one is fishing on a boat or any marine vessel, the navigation system also immediately and dynamically tracks the speed of the vessel and continuously updates the user about it.

Owing to its memory, it can also store 10000 waypoints (points on the path that we followed) and can display 50 unique routes for the user to choose from.

SONAR system and Transducers: 

It has one of the best SONAR navigation and sensing systems. It has 9 points DownVision connector and 25 point RealVision connector and requires a compatible transducer, adapter, and Y-cables for connection and function. Raynet can also be connected as an external Sonar, to enhance sensing and precision. Apart from Sonar, even Radars can be used. 

Raymarine AXIOM 7 Sonar

The type of radars compatible with Raymarine AXIOM 7 is Quantum, HD color, Super HD color, and digital radars. CHIRP technology is used for high-quality 3D sensing while it is not required for 2D, where 50-200 kHz is sufficient. RV-100 is the in-built transducer, which also allows the addition of external sonar without changing its design or configuration.

The transducer consists of an embedded temperature sensor with a long cable that accounts for gyrational stability during the movement of the vessel. 

The best feature of Raymarine AXIOM 7

Despite having a state-of-the-art display, navigation, and ease of use, the Lighthouse 3 software is its most unique and defining feature, making Raymarine Axiom 7 a class apart from other technically-enhanced fishing rods.

With continuous, progressive updates, it remains one of the best Navionics software ever designed and developed. It controls the rod’s quad-core processor and helps in seamless networking and addition of accessories, enhancing the utility, versatility, viability, and inherent design and quality of the product.

It offers equal opportunities and experience to both people who take up fishing as a hobby and people who have chosen fishing as their profession, thereby demonstrating and setting up effective scale-up and scale-down for the product.

Who should be using this?

As this product comes with autopilot and a robust GPS, people who have little to no knowledge of fishing or fishing in that particular locality can use it. As it is also equipped with remote control, one can keep track of the vessel, the fish hauled and one can also manipulate the vessel even when one is not close to the fishing locality. 

One can even stand on the shore and let the rod, connected to the boat do its job! This works best for novices, who have never fished in their lives, people who are terrified of going into the water, and also in case of dangerous water bodies, where there is a huge risk of encountering crocodiles or sudden, strong currents as personnel loss risks can be minimized.

Our ratings- how much did this fish finder average?

After a rigorous and meticulous analysis of various factors, we have come up with ratings for the most important parameters one must consider before buying a fishing rod. 

Raymarine AXIOM 7

Display:  4.4/5

With a smart and savvy display, the Raymarine AXIOM 7 has one of the best display systems that can ever be seen on a fish finder. With a widescreen, preferable resolution, adequate sharpness, and brightness, it is also equipped with multi-touch, hence a keypad is extraneous (ie) not required.

It also has RealVision and DownVision, which gives clearer images of the fish underwater. However, the display can withstand only splashes or water or short spells of rain, at most. Hence it is not suitable for very rainy regions and must be given an extra protective covering before usage. 

Performance: 4.0/5

Its performance mainly depends on Lighthouse 3 software in whose absence, many of its unique features go unutilized. However, it has the highest quality one can expect from fish finders of its price and design. Enhanced by GPS and cutting-edge imaging systems, cabling which increases the stability of the vessel, its performance owes a lot to good design and lives up to our expectations.

SONAR: 4.2/5

The Raymarine AXIOM 7 has a robust and highly functional sonar system. It is also equipped with CHIRP, which helps in 3D sensing in high importance, high sensitivity applications. An external sonar can also be added for enhanced sensing and the system can be coupled with radars as well, making its sensing systems versatile and effective. With GRIB weather sensors, it paves way for usage across all seasons.

Price: 4.1/5

If regarded as an isolated product, the Raymarine fish finder may seem expensive. But when compared to other GPS based fish finders, it offers great value for money. It offers premium technology- be it in terms of imaging, navigation, or display and is well worth the money one pays. If you want a fun and rewarding fishing experience, you must go for it.
