Zetec7,
Well, some of the old C90s I had would turn on at times, but at times wouldn't, and often failed to get a GPS signal, and then the radar wouldn't display. Just too many problems and after my first experience with the old Ray stuff (very popular in the 2000 to 2010 era), I just decided to get new.
Now, I don't know why plotters are more expensive in Canada. And $1500 to $3500 is not necessarily "cheap", it's very reasonable for a marine plotter. But you can get good NEW ones, for less that $1000. What do you think is reasonable for a "command bridge" boat? You don't say what kind of boat you have or what boating activities you do, but even the cheapest boats on this forum are most likely north of $30 to $50K, so spending a few thousand on electronics doesn't seem out of line.
One issue you might have, is just the cost of installing the old C90 and the maintenance on it makes it a bad deal if it were free.
The boat is a '91 Cooper Yachts Prowler 28', with a small command bridge. Due to the dash design, the C90W has to be mounted vertically, with a bracket, rather than installed into a vertical dash face.
This I have already done (very easy, and the screen faces me directly, which is great for visibility), so there is zero cost for installation. I'm doing the wiring tomorrow.
I did run it at home, before installation, and it fired up immediately, locking on to my land-locked position in seconds (looks a little weird, to see your boat position well inland....). The only issue I had was the screen went dark after about 15 minutes of playing with it, as though in night mode....but once I discovered the shop battery I connected it to had dropped to less than 10V, and put an actual 12V source to it, everything came back to normal. I have read several complaints of the same issue, and low voltage was usually the culprit.
GPS lock was within 3 meters, IIRC, although there was no clear view of the sky due to lots of large trees overhead, so I expect that to improve once it's on my fly bridge with an unobstructed view of the sky.
Anyway, I'm locked into it now, so it's time to give it a try.
What I was primarily asking for, from the beginning, was other people's experiences with using it underway, vs. failures and other such issues.
Prices-wise, everything in Canada is roughly 50%-200% higher than the identical product in the US. It's just something we have to deal with - even on Amazon, where items are typically at least twice the price as they are in the US. Anything new and comparable to the C90W is in the $3500-$4500 range, and far outside my covid-ruined budget.
