UAV INTEGRATION
Launch and control your drone from the helm

This marine-electronics
fi rst allows boaters to connect
to a UAV, then control the
drone and view images from its
camera using the Axiom dis-
play. The patent-pending tech-
nology is currently compatible
with DJI Spark and DJI Mavic
series UAV video drones (see
“Compatible UAV Models”).
Features include single-button

With marine multifunction displays, you can
look underwater with sonar, all around the
boat with radar, and even peer through the
dark with a thermal camera. Now you can also
look down from above on your boat, thanks
to the unmanned aerial vehicle (UAV) control
feature built into the Raymarine Axiom and
Axiom Pro MFDs.

launch/track/record func-
tions, GPS link for various
follow modes, and real-time
video streaming to the MFD.
It works like this: First you
need to update your Axiom or
Axiom Pro with the latest Ray-
marine Lighthouse software —
version 3.5 — a free download
directly to the MFD. Then pair
a drone such as the DJI Mavic

Pro (shown left, $1,299, store
.dji.com) with the MFD. Press
Take O to launch the UAV
and track it with a live-chart
display on one side of the
Axiom split-screen display,
which will show the drone’s
location, along with the di-
rection in which the camera
is pointed, the direction the
drone is headed, and the
course back to the boat.
The other side of the split
screen shows a live feed from
the UAV’s video camera with
data overlays that include
the drone’s distance from the
boat, as well as its speed and
altitude.
A Fish- On button is
designed to automatically
capture fi shing action. As soon
as you hook up (for example,
while trolling for tuna or drift-
ing for tarpon), you press the
Hook-Up button. The drone
instantly launches, acquires
and tracks the boat, and starts
recording aerial footage of
the action. You can also view
the action live on the Axiom
display to see, for instance, if
any mahi are following the one
you just hooked.

system in action, visit boating

DJI SPARK
The affordably priced Spark
mini-drone (not shown) includes
ActiveTrack, which can automati-
cally recognize and track objects.
PalmControl mode allows you to
control the Spark’s movements and
take pictures with hand gestures,
with a stabilized two-axis gimbal
for smooth video footage. You can
choose from pano or shallow-focus
modes to get the shots you want.
Return-to-home mode ensures you
won’t lose your Spark when the
battery runs low. With fl ight speeds
up to 31 mph, it offers 16 minutes
of maximum fl ying time on a single
battery charge. $399; store.dji.com

DJI MAVIC AIR
Among the Mavic series is the
Mavic Air (shown left). Designed to
fold for easy transport, it features
top-of-the-line fl ight and video
performance. The three-axis gim-
bal, three-directional environment
sensing, and 4K camera offer the
capability of 32-megapixel sphere
panoramas and 100 Mbps video
capture. Gimbal dampeners create
steady shots. It includes a remote,
but you can also use hand gestures
to launch and control this drone in
SmartCapture mode. With fl ight
speeds up to 42.5 mph, it offers 21
minutes of maximum fl ying time on
a single charge. $799; store.dji.com

Communicate and navigate
like a spy. For example, voice
scramblers are optional with
some models of VHF radios,
including handheld portables.
These can be installed and
used when talking on the air
with fishing buddies.
With practical ranges of 1
to 6 miles, FRS (Family Radio
Service) and GMRS (General
Mobile Radio Service) are
inexpensive (less than $50
to $120). These can be used
to communicate in semipri-
vacy, and some sets have
voice-scrambling ability.
Garmin’s InReach portable
radios ($400 to $450 plus
subscription) let you send
and receive text messages in
privacy with other InReach
devices and mobile phones.
Mobile phones can also prove
useful when fishing within
cell coverage.
Also, don’t advertise your
location. Did you know that
you can turn off your AIS
broadcasts that show your
position yet at the same time
still receive AIS data from
other vessels? Ask your
dealer or installer how to
install a switch to silence
your AIS’s transmitter.
