Attaching the RSS
The line coming from your reel can be tied off to the front
hole in the Remote Sonar Sensor (RSS). If you wish to also
use the RSS as a conventional float, use the second hole to
attach your hook using a lighter weight line. A snag will
break the lighter line if you have to break free. Slip line tech-
niques are not recommended because of the higher risk of
losing the RSS. If you do use the slip line method, use a
lighter weight line after the lower stop, enabling retrieval of
the RSS if the lower line with hook breaks away.
CAUTION: You will increase the possibility of breaking your line if you
use light test pound line on your reel. The RSS is positively buoyant
(is buoyant under its own weight plus .2 ounces of bait and lead
weight.) The maximum amount of weight for any attachment to the
RSS is approximately
weight of any hook, line, weight, swivel/snap swivel and bait that is
attached to the RSS. The RSS itself weighs 1 ounce, and therefore
light test line might break.
Store the RSS in a dry, non-metallic container, such as a tackle box,
in a separate compartment, and isolated from any metallic devices.
