4.1.2
Biofouling
Some customers use a rubber shrink tape, such as DAFLEX ST250
Cold Shrink Tape, available from Digikey (W211-ND), to prevent
biofouling on the ASCENT-AR. It can be used to cover the release
body (Do not cover the hydrophone) and does not leave a glue residue
when removed. Another option is to use an antifouling paint, such as
Interlux Micron CSC.
When using antifouling paint, consult the manufacturer’s safety
data sheet and follow their recommended handling procedure
(safety glasses, gloves, etc.)
4.2
Mooring Line Attachment
A common method used to attach an ASCENT-AR to a mooring line is to thread the rope through one of the
holes in the float attachment bracket, wrap it around the circumference of the release, and up through the
other hole in the float attachment bracket, as shown below. A minimum rope size of 3/8" diameter nylon rope
is suggested.
Pass a shackle through the mooring lug and use the 3/8” diameter (minimum) rope through the shackle.

NOTE:
Keep the hydrophone uncovered to
prevent acoustic dampening.
