The first step in this project is to remove the small holding tab
located on the bottom of the microphone. The best way to do this it
to take a pair of wire cutters and simply cut it off as shown below.
The next step is to drill 2 holes in the bottom of your case (the
example shown here is a Pelican 1300 case). Drill a hole to mount
the microphone at the bottom front of your case (shown below). Drill
a 7/16" hole for mounting the microphone. You can use some
Marine GOOP to secure the microphone in place. Next drill a
5/16" hole on the bottom of your case to run the 3.5mm stereo
cable into the interior of your case. Glue a rubber washer to over
the hole to keep out the moisture with Marine GOOP.
The last step is to run the cable to your camcorders external
microphone jack as shown below. Now you are ready to record sound
along with your videos!
