Scootering with a rebreather.

Any pics of either?

This is the original plate that Gordon made for me about 6-7 years ago, the only picture I could find on the computer.

The latest one (made 4 years ago by a friend in Singapore) extends both ends:

using all 4 screws on the KISS BOV
double bend to prevent jabbing into body when putting chin way down

I don't have any pic for the Golem, but you should get the idea.

Got the idea. Thanks!

I fit a Sea Cure mouthpiece to my Scott DSV and though my hoses get speed wobble when I scoot, it would take an act of God to pry the loop from my lips.

Hoppy scoots like a mad man!

I also use a Sea Cure mouthpiece. It really makes a big difference.

I am sure it works well, but I have an oversensitive gag reflex. Sometimes I gag while brushing the back of my mouth...

So I have to rely on the chin rest...

You can just nip off the back portion of the mouthpiece until it is not an issue. However, don't make it too short; that will start to create the jaw fatigue problem you are trying to eliminate.

Sure I could try that, or could just stick with what has been working perfectly for the last 8 years...

If it ain't broken, why try to fix it ?

You just don't know what you are missing...

When you set the mouthpiece, press the inner flanges with your tongue toward your teeth. This helps reduce contact for you sensitive types.

A great first date is to fit your potential girlfriend with a full size SeaCure and take her diving. You will then know how she is underwater and the level of gag reflex she has...

Good to know.

Not everyone is so crafty to be able to fabricate things, and not everyone has connections with the higher-ups to do these little favors. I am just a little jealous.

SDM do not underestimate what you can do. You want a rest for your BOV look at your rig, think about what you want, gather up the materials go out to the shop & make it. If the first one is no good rethink, modify & do it again. It may take a few trys to get what you want but you may surprize yourself.
Think you can, think you can't, either way you are right.

Thanks in advance.

Hello Freef,

I have found that while scootering there can definitely be more jaw fatigue as others have mentioned. This can be managed relatively easily though by finding the right body/head position and keeping streamlined.

Monitoring/verifying your PO2 while on the fly can be more challenging unless you have wrist mounted gauges (on my rig I have a HUD and my secondary clipped off to my chest d-ring). Similarly depending on the CCR and the scooter you may find its easy/not so easy to reach certain things using the hand not on the trigger.

Since its easy to change your depth very quickly on a scooter you need to be aware of that -- fast dips with big depth swings will collapse the loop volume quickly and spike PO2... similarly riding up will require blowing off some gas (depending on the depth change and how lean your loop volume is already). Generally though I find its not too different than OC, other than managing the loop volume and watching PO2 swings. Buoyancy is buoyancy on a scooter. For example, yesterday I aimed the scooter at the bottom and scootered straight down the line - my PO2 was 1.5 when the hit the bottom, a little higher than I would have preferred, but for the most part I find if you keep the diluent coming in and lay off the O2 you can keep it manageable - or just slow your descent rate.
