I have had the CARD radar detector for several years. I do a fair amount
of singlehanding and it has been invaluable at sea. It rouses me from my
nap with enough warning (at least 10 minutes) to avoid collisions.

The only thing to consider is that you have to make sure the sound is
on. One time, as a freighter was passing nearby, I could not take the
constant beeping and turned the sound off, intending to turn it back on
when the ship was out of range. Imagine my surprise as I woke up from my
next nap to see the unit lit up like a Christmas tree but not sounding
the alarm. Another freighter was almost on top of me. Luckily we missed.

Needless to say, I now keep the sound on all the time no matter how
annoying it gets, especially in high traffic areas.

Hi,
Has anyone any knowledge or experience of the C.A.R.D radar detection
system?

I have had a look at the web site but would appreciate any comments or
feedback. It seems as if it may be a way for me to be sensibly be able
to get more than 20 minutes at a time of sleep even though I know it
will not pick up any ships or fishinjg boats not using radar.

Several times at sea I have talked to shipping who could see me
visualy but could not pick me up on radar due to sea clutter
especially when seas were high.

Thanks
