The bullet transducer is traditionally
mounted on the back of a transom -
so it comes standard with a transom
- mount bracket. However - Lowrance
has designed the HOOK² transducer
with a flat bottom so that they can
easily be installed in-hull too. Most
kayaks are made of a very thin layer of
fibreglass, and Lowrance transducers
are powerful enough to shoot through
the kayak hull and give you a decent
sonar reading.
However… the transducer needs to be
installed properly. We find that a lot of
kayak anglers are not getting the sonar
reading they hoped for, and the main
reason for this is incorrect installation.
There is now only one way to install
a transducer inside the hull- and that
is to stick it down with EPOXY… not
silicon. In the past you could use
silicon, but now the transducers are
very sensitive and they pick up on the
tiny air bubbles in silicon - and this
affects the sonar function. Air bubbles
are death to sonar! Epoxy does not have
any air bubbles- and using epoxy is the
ONLY way to attach your transducer to
the inside of your kayak hull.
You must also make sure to install the
transducer in front of your rudder, as
the rudder also creates air bubbles
that will affect your sonar view.
Another important thing to ensure is
that your sonar plug is pushed ALL the
way in! There are three circular ridges
on the plug – all three of these ridges
need to be fully inserted until they
cannot be seen. This will make for a
perfect watertight connection.
The bullet transducer that
comes with the 4-inch
HOOK² unit is an entry-
level transducer. It can
show a maximum depth
of 50 metres (so you can
read bottom at max 50
m), and it can show fish
arches between 30m and
40m – depending on
water conditions.
If you require a bit more detail a nd more depth than the bullet transducer can
offer, then we suggest upgrading to the 5-inch HOOK² model. It is still super
affordable, and you get a bigger screen! The 5-inch model comes with the
SplitShot transducer. You can read bottom at max 120m, and you can see fish
arches at max 80m. You also get the added feature of DownScan Imaging- to
view structure up to 30m beneath your kayak.
