The original question was about the placement of the SPG 
in a system called DIR. The enquirer wanted to know, within 
that system, where other DIR divers clipped their SPG.

There is no console in DIR, Michael, for the simple reason 
that consoles drag, scrape and get in the way - even when 
they are clipped off. They trap line. And they place an untoward 
strain on the hp hose. Further, they are impossible to mount 
in a streamlined fashion so that information can be read at
a glance without having to unclip and/or handle them first.

As you have discovered, you have to go to ridiculous extremes 
just to carry the thing in an out of the way place. In your case,
by keeping it as far from its intended place of use as you could
think of - and on a long hp hose to boot! This is the height 
of inconvenience and inefficiency. Esp. considering your compass 
(which you say you use regularly) is attached to it. Michael, 
that's like keeping the speedometer in the trunk, no?

The DIR system on the other hand, enables the SPG to be read 
at a glance and keeps the diver tight, tucked in and stream-
lined -  which is a distinct benefit when moving through the
water, whether swimming, in current or scootering, or negotiating 
tight spots, whether in caves or wrecks.

Those other things you have attached to your console would be 
more manageable and accessible if you put the depth gauge
(and the computer if you must) on your wrist, the cutters on 
your belt, wrist mount the compass (on a piece of bungy if you 
like to swim with it held out in front of you) or put it with
the other stuff in your pocket.

No-one has ever been able to explain anything other 
than DIR as a 'system'. So as far as diving is concerned,
there is only one 'system'. And what you're diving is a mess.

Michael, you have yet to discover what works best for you.
You've hung nine separate items (that's 9 - count 'em!) off 
a long hp hose to create one of the all time great gear fuck-ups. 
And by way of proof, look at the assinine way you have to dive
it - with the whole shebang sitting in the crack of your ass!
