electronics upgrade q
 

Posted this on the wasteland that ASA has turned into, so much background
noise I don't think anybody saw it...
Been pondering for awhile how to upgrade the electronics on the boat. I
guess they were state of the art when she was built in 1979 (loran, ancient
GPS, Raytheon R10X
radar, etc) but the radar is broken, loran is kind of an old joke, and the
GPS probably has wooden components. The radar needs a new magnetron tube
that would cost over $600 just for the part, so that's out of the question.
The old depthsounder gives good readings in shallow water, but tends to go
crazy in deep water, sometimes showing very shallow depths for no particular
reason. I was thinking I had a submarine 20' under me quite often on the
delivery trip up Baja!
Was leaning a little towards the whiz-bang mapping GPS with radar overlay
technology, but after reading about split screen mapping GPS/sonar units in
Practical Sailor, I'm now thinking of going that route with a stand-alone
radar. I really like the idea of seeing bottom contours next to the "you
are here" GPS display right at the helm. Any thoughts? What would you do,
and why? I'm planning to be cruising for several years in unfamiliar
waters, BTW.

Wow!
Lots of questions. I can't help you with the radar stuff but Garmin makes a
neat little unit for $999.00 at West marine. It interfaces with most NEMA
electronics.
In Baja it might have been whales but I wouldn't know.

I sail on lake Erie and the Garmin 72 works well for me.($154.95 at wallmarts)
It comes with all the coast guard placed buoys mapped out. Accurate to 15 feet.

Good luck,
John
