What type of DSMB do you use ?

[Pierre Farrugia]

Hello all,

When diving a rebreather, does it make difference what type of DSMB you use? Sometimes I hear that the self inflating are better, is this true and why?What type of DSMB do you use?

I have the Buddy self inflator so I don't have to mess about with the AutoFreeflow unless something goes wrong. I clip it on the D-ring on the YBOD right wing with it's velcro wrapped round the reel handle (small 50m McMahon). A friend videoed me launching it once. 8 seconds from the hand reaching the clip to the reel spinning. Even I was surprised (and a bit smug).

I also have a simple sealed mouth one with a 20m spool and a yellow one with just a piston clip to run up another line as an "I'm in the poo" signal but they only come out for serious dives and I've never had to use them for real yet.

I have exactly the smae as Nigel except they are on a CD 120M reel and a Halcyon 100 Pathfinder reel (doubles as a wrecking reel)

The Buddy Crack bottle ones are worth there weight in gold. if you can't get one over there let me know and I will sort one out for you. With the rebreather they are virtually essential.

Hi Pierre, I have the AP auto inflate DSMB. I also have the accessory pockets for the bod. The DSMB fits in perfectly, no good if you want to leave the reel permanently attached though but fine for the blob on its own. As per the other guys though it's best to carry a back up red and a yellow that you hope to never use.

Thanks Andy,

My only problem with them as they seem very bulky, having 2 of them!! Anyone stowes them differently? DO you use the sausage or the 25kg?

Thanks Andy for your offer, if I have a problem will contact you, from where you get them cheapest?

I think the guys were alluding to having one self-inflator and then a normal red & a normal yellow for those occasions when you've forgotten to fill the crack bottle or having an Eeek moment.

PS here's a tip on how to not win friends and influence people. Wander round the boat cadging air off OC divers cos you don't want to use the box's gas(es) to fill the 0.1l bottle. Cos I'm tight like that.... Happily I can usually blag mine off of Finless. Wait for him to kit up and get ready - usually about 45mins before the shot goes in - and when he remembers his tins are still tied to the bench and he's flailing around like a stuck pig, nip round the back and swipe a bit of his back-gas whilst pretending to untie him

Only the main blob has a crack bottle. The others are stowed in the left thigh drysuit pocket to stay out of the way. I had a bottle valve pack up on me so I took the opportunity to upgrade from my original A-clamp to DIN a couple of years ago. They are so quick and simple to use the biggest danger is somebody helpfully winding them up for you on a dive boat and you forget to refill it - well I have. It is so disappointing when you reach for the valve and get nothing. However filling it from the AutoAir is no problem just a bit annoying.

Interesting, we've only ever use 1 red and 1 yellow - the yellow being a binary signal for ' I have a problem' even if that 'problem' is my other DSMB is buggered.

I like your idea it stops a scramble if the problem is minor- incoming.

I have the Halcyon 6' closed bag, but find it bloody huge. I have just bought the 3' one which you can inflate orally. I also carry a open ended small yellow one.

Hello can anyone pop a pic of one with something at the back that I can use as a scale, to picture it's size? Also do you use an DSMB or a 25kg bag? What crack bottle size you use 0.1l or 0.2l? Anyone knows it's volume eg 15kgs of boyancy As I think I will order one soon. From which shop is chepest?
