    Are all the probes fully submersible?

    Random thought are the probes fully submersible? Could one in theory have them upside down or sideways to let any possible bubbles escape without issues?

    You can put them fully under water and they will still work. The problem I believe is with long term use. The rubber top that is holding the wiring to the probe itself can become brittle after being submerged in saltwater for long periods of time. Once it becomes brittle it can potentially crack and allow water into the top of the probe and wiring contacts.

    Not entirely correct. The brittle issue applies for all probes (with the exception of the temp probe, and conductivity probe), but many cannot be fully submerged even if you are willing to risk the brittle wires. If a pH or ORP probe is not fully sealed or has a fill hole, you can ruin the probe fairly quickly by submerging fully because saltwater mixes with the reference fluid.

    You might be an engineer if...You have no life and can prove it mathematically.
