Fit for the suunto Sensor ?
I use it with the aeris sensor. (hollis and oceanic) on the Aqualung LX ACD first stage.
Advice on placement: put the sensor on the side opposite your tank valve knob.
I don't have a Suunto, but i do use as an extender for my Oceanic sensor and works well. Without the extender my sensor was rubbing the other hoses.
I used it for a Uwatec Air2 o2. Worked fine..
I bought this extender so I could attach the Suunto hp sensor to the high pressure port on my regulator's 1st stage. It worked perfectly.
I used it for a oceanic vt4 sensor. If they are the same size it should work.
I ordered this for my father. the high pressure ports are usually standard and it worked perfect for him. he didnt have room close enough to his first stage for his transmitter and this solved the prob. if your prob is close to that it should work for you!!
