- Hi, guys! I'm Mark, a scuba diving instructor
from Safe Diving.

- So, in this series of videos we're going
to be taking a closer look at an entire range
of the newest scuba diving equipment,
and all of these videos are sponsored
by Mike's Dive Store,
the UK's largest scuba diving retailer
and they hold most of these items in stock at all times.
- They're also doing their bit for sustainability,
by moving to eco-friendly packaging
and they also donate 1% of all their online profits

- So, let's jump straight in.

Okay, so here we have the SCUBAPRO MK 25 EVO
with the D420 "2nd Stage".
So this is a lovely regulator set.
It looks a little bit different compared
to a sort of traditional design,
but trust me it is actually really nice
to breathe from.
If we take a look at the "1st Stage" first,
so the MK25 EVO,
this is a lovely "1st Stage".
This is a five port swivel turret
and that basically means
that you have four low pressure ports
around this turret,
and these are going to swivel around
and that just makes hose routing much more natural
and the hoses naturally kind of move as you pull on them.
So you're not going to damage your hoses too much
by pulling them, just by moving around.
You also have this fifth port coming straight
out of the top.
So that's particularly useful for if you're diving
on twin sets so you can have that sort of extra,
so the hose coming out of there,
especially if you're dry suit diving
it gives you a bit more flexibility
about where hoses come out from.
Moving down the "1st Stage" you can see
we've got these little holes on the inside
and then you might be able to see it on the close-up
but it's pretty small.
You actually have a blue coating
on that main spring on the inside.
Now this is SCUBAPRO's XTIS,
which basically improves the cold water performance.
It's a little bit like a Teflon coating on that spring,
which means that ice finds it really hard
to actually form on those moving parts.
Again, it's improving the cold water performance,
so the regulator is less likely to freeze up.
Two high pressure ports, one on either side
just means that you can dive
with a submergible pressure gauge
and a wireless air transmitter if you want.
Right now this is in the A-clamp
or yoke configuration.
You can also get it in DIN,
depending on your preference.
Moving from the "1st Stage",
then connecting the two stages.
We have a rubber hose, traditional rubber hose.
They're nice and tough
and they're quite neutrally buoyant.
They tend to stay where you want them to in the water,
and then we move down to the "2nd Stage".
So this is the D420.
D420, as I said earlier,
a slightly unusual shape.
What they basically did is they moved the diaphragm
a little down.
So it's a little bit lower
which actually improves the performance
and the sort of the way breathes.
It's one of those things if you get
a traditional "2nd Stage"
and then you swap to this one you can notice
a bit of a difference in that sort of breathe quality.
One thing that I like about it,
is that it has a hinged purge button on the front.
So even you've got really big clunky gloves,
you can push it a little bit just to get
a little bit of gas or you can push it a lot
to really kind of sort of purge that "2nd Stage".
On the top, we have big Venturi Adjustment control.
So this is going to prevent it from free-flowing.
What it basically does is redirect the air flow
on the inside of the "2nd Stage".
So as soon as it starts to free-flow
it interrupts itself and stops it.
The mouthpiece is held on by a reusable cable tie,
which is a really useful sort of piece of kit.
That way if you ever need to change this one
because you've bitten through it,
or for whatever reason.
You can take that off and then reuse it,
so you don't need to carry a whole bunch of spares
in your kit bag.
Okay, guys.
So that was the SCUBAPRO MK25 EVO
with the D420 "2nd Stage".
A great regulator, it's at home both in warm
and cold water, so you can dive it anywhere.
It's a little bit unusual
as far as the kind of design
but actually, it does breathe
really, really nicely.
