Summary:
The Raychart 435i performed well on our test session, with quick updates when the scale was changed. Display size is excellent for the price, easily visible at low speed and excellent in daylight.
The chart colouration is great with close renditions of paper charts available. Navigation figures are big and bold. Like all multiple purpose tools, there is a bit of getting used to the menu system, but it's not at all a clumsy unit.
I found the menu system is easily to work using the multi-directional Trackpad and accompanying entry buttons. The screen has a status display on top and a dynamic function list below complete with pop-up screen menus. You soon get the logic from the concise manual and it is easy to use.
Accuracy was good on our trip. Lights and features all popped up about where they should have been as we passed them by. Only real drawback was the gloss screen. This can reduce visibility at night due to ambient light glare; it certainly made it darn hard for me to photograph at sea.
In summary, this is a competitive chartplotter on price and most definitely in terms of quality.
The fact the 435i can be linked with a PC for waypoint storage is another advantage. Also at a retail price of around $1800, plus chart costs it makes a good choice for a boatie short on dashboard space.
