I received the following question from a university lab and will post my portion of the answer in a reply. Michael will post more details on pressure sensors and technical answers.
"I am currently involved in a project that involves building the seaglide kit. We have finished assembling the seaglide, but now we are looking to put some sensors on it. I found the sensors link on the seaglide web page and it looks like there is some kind of kit out there that includes all the necessary parts for the pressure sensor build, but I am unable to find a link to any such package. Is there a way to purchase the pressure sensor supplies as a kit? I was also wondering the depth limits of the seaglide? And what is the resolution depth of the pressure sensor?"
