Raymarine has introduced a major upgrade for its RealVision sonar system, rolling out changes that will produce clearer images at depths that increase its saltwater versatility.
Rather than just increasing the frequency of the sonar, Raymarine’s RealVision MAX update – standard on the new Raymarine Axiom2 Pro range of fishfinders and chartplotters – focuses on generating a higher-definition snapshot of fish and structure below a boat.
Raymarine likens its second-generation RealVision technology to an MRI machine that gains an image of a person’s body by building up individual slices into an overall picture of what the body looks like.

By increasing the number of slices that the sonar can make of the water profile below a boat, Raymarine has been able to paint an even clearer picture of what it looks like.



It has combined this with using a much narrower sonar beam. This has the effect of ensuring the individual sonar beams don’t overlap, helping to create a much clearer picture.
Raymarine says the beam angle of its through-hull transducers has been reduced by as much as 30 per cent to help with this.
In a separate development, Raymarine has increased the contrast between the sonar colours displayed on its Axiom2 Pro devices so that there is more difference between showing structure and fish.
According to Raymarine, the new RealVision system’s ability to separate fish from other structures makes them “pop within the water column more than they ever have before” – a boon for anglers in open boats dealing with glare and direct sunlight.
Raymarine’s RealVision MAX will be included with its new range of Axiom2 Pro chartplotters and fishfinders, as well via a RVM1600 “black box” to allow owners who do not want to upgrade to the new Axiom2 Pro range to add the upgraded RealVision to other Raymarine products.


Because the system’s output has increased to 600 watts, the sonar will work at greater depths and with more clarity – up to 365 metres deep with any number of backwards-compatible transducers and up to 900 metres when combined with a 1kW transducer developed to take advantage of RealVision’s improved system.
Raymarine will offer the choice of one transom mount and three through-hull transducers – no offset, a 12-degree offset and for deeper vee hulls, a 20-degree offset.
The RVM1600 black box with 1kW sonar, DownVision, SideVision and RealVision 3D, costs $3299.
