The Caddy Lite is not much bigger than a mobile phone. A belt clip is provided. A USB lead is also provided to download maps to the device.
The purchase includes one map credit and a list of maps can be seen on the supplier's web site so that potential buyers can check that their course has been mapped. Up to 10 maps can be stored on the device at any one time.
The word "map", to me, conjures up images and diagrams, plans of holes etc. but this is not the case. The information is displayed in numbers only - nice easy to read, decent sized numbers.
The display always shows the distance to the front of the green just above the three main numbers. The three main numbers will vary depending on position and number of bunkers, water, end of fairway etc. Two numbers are sometimes used to indicate front of bunker and distance over it - very handy for that often asked question "Can I carry the bunker?"
The Caddy Lite Deluxe comes with a charger, but I do not know whether the Caddy Lite does. Having said that, both the Caddy Lite and Caddy Lite Deluxe can be charged using the USB lead plugged in to your computer.
In my experience, one full charge lasts for two rounds (switched on all the time of course) - a total of at least eight hours without becoming fully discharged.
A point worth checking before you purchase - does your club allow the use of distance measuring devices. The R. & A. formulated a rule which in simple terms says that clubs may make a local rule to allow the use of distance measurers but if no such local rule exists, you will be in breach of the rules of golf when using one.
If you want a GPS system with pretty, colour pictures this one's not for you, but if you want some basic, straightforward information on each hole, on a simple to use device I doubt you'll find anything better.
In my opinion it is excellent value for money.
