Q - What software do you advise me to start with?

A - Oziexplorer, the trial version of which is very comprehensive, is downloadable free from www.oziexplorer.com and is fully compatible with virtually all raster charts. This is currently the best, and cheapest software available.

Q - I don’t have a laptop, but am thinking of buying one, what should I look for?

A - If buying new, buy from a reputable supplier, and choose one from the “big three”, I.e. Compaq, IBM or Toshiba. All have models which have all the bells and whistles you will ever need. Don’t forget the second-hand market, there are many good laptops available at knock-down prices from auction sites like www.ebay.co.uk, but care is needed in choosing a machine which will give long service and tolerate a certain amount of abuse!

Q - I have a bulkhead-mounted GPS. Can this be linked to a PC or laptop?

A - Yes, although it will possibly entail removing the back, and closely studying the instruction manual to pick up the input/output terminals, not a major job if you are reasonably competent with a screwdriver.

Q.- What about the charts? Where can I buy these if I download Oziexplorer?

A - There are many bitmap charts which can be used with the trial version of Ozi, and if and when you decide to purchase the full program, ($75), these same charts can be re-calibrated for the more sophisticated map projections and datums which are supplied with the full version of the software. CD-Roms are available which contain many “Admiralty” charts for a relatively modest outlay.

Q - Will I be able to use the software for navigation immmediately? Or will there be a lengthy learning process?

A - Oziexplorer is a relatively simple application, and is user-friendly, with comprehensive helpfiles. Even so, as with any new technology, you have to give yourself time to understand how it works. Creating the link between PC and GPS causes some newcomers a few problems, but these are soon resolved. Obviously someone well-versed in computers will master the software more quickly that a complete beginner. Learning to use OZI’s many facilities takes time, even for an expert, so comprehensive is the program.
