Underwater slates
These are used to write underwater and
record data. Its important to have then
strapped to you arm in a way that allows east
removal in case of entanglement. But also
attached so you can drop them to assist
snorkelling.
Its best too practice in the pool before going
into open water so you can improve your
underwater writing skills.
Underwater cameras and
housings
Modern digital cameras now have
underwater settings which take great photos.
Most manufacturers sell underwater
housings (Figure 7.2) which allow you to
take photos underwater.
Survey digital video cameras
As digital technology increases, so does the
range of underwater recording devices
(Figure 7.4). It is now possible to buy
waterproofing solutions and housings for
tablets, Ipads and phones.
In the not too distant future, you may be
taking your tablet underwater to record data.
GPS and marine radio
This device allows you to take your GPS
while at a research site. Figure 7.4 shows
other emergency features. In Australia you
have to have a licence to operate a VHF
radio.
