    One - decanting whip? - will have a needle valve and a decent, probably digital pressure gauge in order to accurately move an amount of gas (oxygen, helium) from one cylinder to the other. The other - transfer whip? - will be a pipe with an optional gauge and is used for filling tins from other tins, e.g. suit inflate, balancing gas, etc.

    The latter's around £100 (http://www.aquanauts.co.uk/dir-zone-decanting-whip) and widely available from all scuba shops. The former is circa three hundred and a specialist bit of kit.

    Curiously, AP have a slightly different view as they sell a decanting whip with, or without, gauge and no transfer whip.

    I wasn't very clear.

    The 'simple' one is just a tube, with or without a gauge and a pressure release valve.

    The other 'specialist' one is for gas blending and will include a quality, probably digital, gauge and a needle valve for accurately controlling the flow of gas. And a pressure release valve. I've seen the gas blending whips for £300 to £500. Example https://www.narkedat90.com/blending_whip_digital_gauge_p/bwdg.htm

    An example of using the blending whip would be for 32% at 232 bar which requires an empty tin and 32 bar of oxygen added which is topped off with air. You cannot measure exactly 32 bar with a normal gauge; you'd be lucky to measure it within 10 bar.
