How to use this guide
Within this article, which will have particular relevance for those wishing to retrofit or embark on upgrade projects, we’re going to divide the GPS and chartplotter market up into three categories: entry level, mid-price and what we might describe as ‘top tier’. But let me make it clear: the process isn’t exhaustive and hasn’t included a test and analysis of each product. Rather, the purpose of this article is to provide something of a ‘showcase’ in order to help you isolate those products that, potentially, might be best suited to your needs and your pocket.
Technological advancements mean systems are constantly improving, ever on the move, and certainly the introduction of apps, both purpose-made and compatible, is affording an incredible ability to upgrade and expand plotter and sonar systems like never before. Then again, what you and I may require in terms of functions, etc. will likely be quite different. However, modern technology does result in astonishing flexibility and customisation opportunities.
But before we kick off with our product highlights, let’s just review a few essential points associated with these products, known typically in the trade as ‘multifunctional devices’, or MFDs.
