I TEND TO GO FOR A SIMPLISTIC KISS approach, which is very similar to the Hogarthian style.
This has in many ways been appropriated by the DIR [Doing It Right] group, but if you look at most of the top technical instructors we have a very similar set-up – simplistic harness and streamlined equipment, all meant to keep the clutter down.

My choice of computer depends on what I’m doing.
My favourite is the Liquivision X1, which is like the iPhone of computers – it’s such a cool gadget. It’s the only computer that makes me smile when I’m using it.
But I also use an Apeks Quantum, a nice simple computer, and occasionally I use a Suunto HeLO2, especially if my students are using them, because I tend to match with them. But my first choice is the X1.

I use a Halcyon wing, harness and backplate. I have a couple of high-quality wings, but the Halcyon seems well-made and solid.
I look for style too. The way I teach my technical diving, I advocate streamlining and simplicity, and the Halcyon stuff really fits in with that.
Like many divers, I started out with a Buddy Commando BC, which I still have and still use occasionally. You can’t beat the old stuff.
Apeks also does quite a nice wing and harness, so I’ve used that in the past.

I’m a big fan of Apeks regs. With technical diving I’ve got two on my twin-set, one for the stages and one for the suit-inflation bottles. They’re simple, cost-effective, reliable and very easy to service.

I’ve got two rebreathers, a KISS and an Inspiration. I’ve had the KISS for three or four years and the Inspiration only for a year or so, but the more I dive with the Inspiration the more I like it.
I tend to focus on open-circuit when I’m training, and use rebreathers for my own diving, so it probably comes down to about 75% open-circuit and the rest rebreather.

At the moment I’m wearing an Oceanic Shadow, although I go through a number of different masks – whatever does the job. I’m not particular about masks.

Fins are also among the items I’m least fussy about. I’ve got two pairs. One is a pair of US Divers fins that I bought in 1987 and never changed, apart from changing the straps a couple of times. They’re well-worn, but they do the job.
I have a pair of Jet Fins as well, so I keep it simple and straightforward.

I’m using a compressed Neoprene suit at the moment. It’s actually a bit of an experimental suit that O’Three put together for me, because I wanted to test out some 1mm Neoprene panels.
I’ve done about 200 dives and I’m very happy with it, and O’Three has now launched a 1mm suit on the market. Before, I had a Hunter VSN 1100 Tek.

This is one of the things that’s important to me, as I spend a lot of time in the water. I’m a big fan of Fourth Element stuff. At the moment I’m using Arctics under my drysuit.
When it’s really cold I’ll use a Subxero, but it’s almost too hot to wear at other times. I usually wear some combination of Fourth Elements, from a thin Xerotherm in summer through to the Subxero.

In summer I use Fourth Element gloves, and in winter I’ve been using Typhoon Hyperflex gloves. These fit really well, cut down on flushing and keep my hands much warmer. The instructors at Wraysbury Lake told me about these.

I use a Salvo 21W HID. Salvo doesn’t exist any more, but my lamp has been all around the world with me, never gone wrong and never given me a problem.
For back-up lights I tend to use Halcyon Scout LEDs. I use them mainly for wreck-penetration diving, but I leave them on the harness even for normal diving because it’s easy – they don’t get in the way.

As my overall philosophy is to use the right kit for the job, my choice of reel depends on what I’m doing. For wreck-penetration diving I use a Kent Tooling reel. It is incredibly solidly built and very reliable – it has never let me down.
For normal UK sea diving I use a Narked At 60 Tech, which is a small, compact reel with 65m of line. I also use Halcyon spools as back-ups.

I have a small generic belt-knife, and I recently bought an Ezicut line-cutter, which is pretty impressive. It’s very compact, but the great thing about it is that it can slice through rope, line and even webbing with no effort.
A knife won’t fit the type of one-piece harness I have very well, so a line-cutter is a good idea.
