Scuba Toys seem to be out of those and don’t list the price. I found others on the net in the $200 range. Not sure I would ever use one to be honest. We have to trust human beings with our gear at some point in diving. I hope they find the guilty party and prosecute them to the full extent of the law. Knowing what the possible repercussions could be is the probably the best way to ensure air compressor owners keep their equipment in proper working order. I’m not sure what type of policing and testing/inspection compressors even go through. Very sad story in any case. I was planning to make a dive trip to Cabo next summer. I would really like to know who was responsible and what changes will take place before I go.
