Due to the Tritons not yet being available in Australia I bought one from the US. It arrived five days ago and has taken that amount of time to figure out all of it's features.
I have read a lot of posts about the unit being unreliable or hard to figure out. Most of this seems to be due to the instruction manual being too simplistic and incomplete and most expecting it to operate like all their past Magellans.
After the big learning curve with lots of fiddling and head scratching I have found the unit to be a good one and I must add that everything works. The unit will freeze on occasions, usually due to operator error and pushing it to do something that you shouldn't, but, hey, what computer doesn't on occasions?
Most of the features are a plus and once you get the hang of the format, easy to use.
The Vantage software is just brilliant and seems to contain anything that is needed.
Just remember that the OS is nothing like what you are probably used to and it will take some time to get it all together...... I wanted to chuck it to the sh..house on numerous occasions but now the Explorist 500 is second fiddle.
