You mean the DC power connector like this:

The actual sizes vary.

You probably mean the RF choke. It is a doughnut or cylinder
shaped chunk of soft iron to reduce emission of high-frequency
electromagnetic noise from the electronic device.

Better known as a toroid

Only if it's a toroid shape. Many aren't, toroids are handy
if you're going to wrap the wire around them, but many of these
power cord chokes are just hunks of ferrite surounding the
conductors.

I've made big ones of these by stuffing steel wool into tubes
that have wires running through them.

I've been running Lowrance AirMaps since they were introduced.

The AirMap series is complete with customizable road map software that
you download into the unit from your PC. EVERYTHING is included with
the AirMAp series. They are totally upgradeable by dl'ing the upgrade
from their site. Even the Jeppson upgrades are dl'able. ( for a price
of course)

I've been using the AirMap 1000 since it was released in March and
love it.

B U T!!!!!!

They have now come out with color and I GOTTA have that!!!!

My AirMAp 1000 is for sale, complete, under warranty, $625!!!
