nice.thanks

Hi Mark. Recently on a trip my buddy gave the dreaded hand across throat and wide alarmed eyes (!) on the Irako at 30m. I have just finished my IDC and gone through teaching all the scenarios of secondary donate and lifting the arm so they can grab etc However, my instinct was to primary donate and I reached for my octo on my harness. I know that primary donate and secondary on a necklace is an option. Since, I now know how I would react in that situation I am considering moving to primary donate and secondary on a necklace. Is it possible that you can make a video on this setup for BPW and where / how the long hose is stored? Also, how long approximately should the hose be on the octo? Keep making the awesome videos. Thanks again, Doug

Sure, the most common setup is with a 210cm or 150cm primary hose and a 55-60cm short hose. It can depend on whether you're diving singles or twins and the thickness of your exposure protection But, you can use a piece of string tied to your 1st stage to work out how long you need the hose to be. The short hose is put in place first over your right shoulder and you basically want the shortest hose to place the 2nd stage under your chin to reduce any excess hose. The long hose starts by routing down your right side _behind_ your shoulder. Then it hooks under something on your right hip such as a drop-down knife on your waistband. The hose routes back up across your chest to the left of your neck, wraps behind your neck so that it sits on your right side.

Thank you

I presume this is akin to the dump valve on a BCD. I got the notion from observing this video that if you can route the line to your shoulder (near your armpit), enabling you to easily pull the dump valve to release air, it would simplify air dumping for divers rather than prying it from your lower back (Sidemount diver). The routing would resemble how you route your primary torch. What are your thoughts?

Routing the corrugated hose from the lower back position? The main downside I can think of is damaging that corrugated hose in an overhead environment and you can't inflate. The elbow joint is typically taller than an OPV so it's more likely to be the first thing that scrapes on the ceiling.
