I dive a SCR Dräger Dolphin and have purchased two Oxy2 units. Both have had minor water intrusion to the point the circuit board shows some corrosion and they have quit. Does anyone know where to send for repair? I sent to Scubapro and they no longer sell or service - just sent it back. I have another wired O2 monitor, but this unit is great when it works as it changes deco on the fly as the O2 changes. I also like the fact it's right in line with the inhale instead in the counterlung. Any help appreciated. Or, anyone have a working unit to sell?
