Most drysuit divers use undergarments with a front zip design, and therefore will
either have to cut another hole in the insulation (not particularly recommended)
or run the tubing up over the lowest part of the zipper and down to the base
unit. In any case, care should be taken to choose the location of the base unit so
that unnecessary holes do not have to be repaired later.
The hose that comes with your Halcyon valve will be too long for most users, but
is designed to allow individuals to trim the length in accordance with the dis-
charge location.
Mark the location of the valve after carefully
deciding on where you want to make the cut
into the suit.
2) Creating a Hole
Halcyon recommends using a professional punch (such as a 3⁄4” grommet punch)
to create the hole for the valve installation. When using a punch, place a small
length of board on the inside of the suit to create a strike surface for the tool. Be
careful not to damage the inside of the suit with the support board. A small hand
towel can be used under the board to protect the inside of the suit. Make sure
that the suit’s internal suspenders are pulled clear of the valve’s location, and run
your hand along the inside of the suit to verify that you are not cutting through
the extended edge of a sealed seam. With a hammer, use the punch to place a
very neatly sized hole into the suit. This method is especially recommended for
fabric-style drysuits, although it is very effective for neoprene as well.
