The Wireless saga. Wireless computers are now made buy many manufactures, to many to name. Like purchasing other computers you should consider much with these. I have used these and had a couple as well. I like the Aries GT750 and therefore the Oceanic as they are about the same. That said there are some things you need to know about these. There are additional points of failure, you now have two batteries one in the transmitter and the other in the computer, therefore two ‘O’ rings. Connectivity to the transmitter can be a problem. Normally mounted in the first stage I have seen some add an 18” HP hose and move it to the LP inflator area over the shoulder to ensure connectivity. When they loose the connection they will provide an annoying beep and then flash indicating that no gas reading is available. Holding my arm on top of the head helps restore connection. Out of the water distance is smaller to maintain connectivity. Wearing the computer on the wrist is another consideration.
