I enquired about the fishing drone and swellpro uk were very helpful
with all of my enquiries. When I finally purchased the FD1 it arrived
within a couple of days and I took it out straight away. I can now cast
my line out 500 metres and catch much bigger fish! I might purchase the
fish finder nextStockport, UK
I bought the Splashdrone 4 to capture footage of me
and my family whilst out on our boat. The fact its waterproof means I no
longer have to worry if it goes in the water. I'll even drop it in the
water to get underwater footage and then fly it right back to the boat.
Excellent camera and can shoot RAW photos so I can really create some
brilliant pictures. Thanks Swellpro UKMiddlesborough
