    I have a mares icon hd & need to know which size & type of pin I need to go between transmitter & short hp hose as there appears to be 2 straight ones off different lengths & a one with a collar.

    I don’t know but you probably want the one with the collar, the only time I’ve seen a gauge without the collar is with a Suunto gauge

    I have Aqualung transmitters and used the regular swivel pins with a collar. I imagine they will be just fine with the Mares transmitters.

    Just try it - the worst that could happen is a leak. In which case you'll know it's no good. Put some O2 grease on the o-rings.
