I bought the "Vision" option for other reasons. I'm not a huge fan of having the chartplotter
pick my course. But now that I have it, I've been known to use it from time to time. Here are some of my observations:
- Sometimes, based on my draft
, it will run me over rocks that are just a few feet or less below my keel
. Even if there's good water
on either side. Imagine doing that in 2-3 foot seas. Ouch!
- Other times, for some unknown reason, it will lead me the long way around an area that's actually plenty safe for me.
- If the route
is too complicated, it won't be able to calculate one at all. Which I suppose is a good feature. But when I'm going a relatively short distance through a place with a lot of reefs
and islands, like Casco Bay, that's when I'd be most likely to let the computer take a stab at suggesting a general route
, which I'd verify and apply common sense to before following.
When it does work
, it's a nice feature. Fun to play with, but by no means a substitute for due diligence in navigating. I wouldn't pay extra just for that. The Vision option has other features which made it seem worth it for the whole package.
