Is anyone using or have knowledge of Garmin Radar?    I like Garmin

Minimum would be to monitor icebox temperature and voltage to compressor so
that I can see on-off cycle and resulting temperature vs time for a 1-2 day
period.

I have a non-laptop Shuttle computer on my sailboat. I would like to be able
to access marina and other WiFi points when available. I have talked to some
of the marine WiFi providers and they only provide hardware that works with
laptop computers. At the Oakland boat show the ...

I'm trying to get a land-based VHF marine monitoring station up and
need to make my antenna have some degree of directionality.  I need to

All 6 wires corroded off the plug that goes into the back of my Modar
Triton 55/75 VHF marine radio.  Can anyone tell what wire is supposed

finder sensor, I should be able to set it up inside the hull as long as

I just relaunched my boat after painting the bottom, installing new
zincs and instruments.  That was in March of this year. Around the 1st
of July, I scrubbed the bottom in preparation for a race, and noticed
the zinc on the strut was nearly gone, despite only having been in the

I'm new to the group and fairly new to boating. I've just purchased a
Wellcraft 210 Suncruiser and I've got a spare new battery (800 cold cranking
amps) and would like to run a power inverter off of it to run a small fan
and maybe a boom box. Nothing special or overpowering. A ...

Anyone have any knowledge of this German made electronic distres
device? It seems to me that it was just to old and outdated for curren

I must be getting stupid as I grow older.  I can't seem to figure out
the difference between the Garmin 298 and 498 chartplotter / sounder
combo units.
As best as I can tell, they both do the same thing...  Maybe the

Group,
I've started back into marine electronics fitting and repair again. We
have an older scanner MRT-136) that is part of an MD-3600 radar system.
The radome got wet (yes Larry other manufacturers do get wet from time

I have been offered a really good deal on a high amp (325 amp) fire engine
alternator by the city vehicle maintenance shop.  It was purchased as a test
unit but due to some budget cutbacks ended up being to expensive to equip
the whole fleet.   This monster is hot rated at 200 ...

Since their installation when the boat was configured around 1988 i
Germany, I am curious about advantages of having them remain in th
vessel for the future, when I cast off to other countries from the US.
Are they still needed or is there standards of uniformity in mos

I'm a newbie to boat electronics, so I'll apologize up front for some
basic questions.
I've got a 32' flybridge sedan that I use on Lake Lanier in Georgia

I apologize for this long delay in responding, but I have been without
land-line phone service since Thursday night, hence no Internet. It
