The transmitter is rather neat in that it can either seal with an O-ring above the threads when it goes directly into a regulator port, or it can be sealed with a regular gauge spool when it is placed on the end of a hose. Nice there are options since there are so many different 1st stages and all the possible HP port configurations. While some have it lucky and can install the transmitter in a clean protected manor others may not have the option. When screwing directly into the regulator is not a good idea, the hose comes in. I would avoid if possible, the spool O-rings go out often enough I keep multiple spare spools ready to go. Don't even change the O-ring just change the spool right there on the boat. I have also seen a longerish HP hose used to put the transmitter over the shoulder. It was to solve a computer drop out issue.
