[PSUBS-MAILIST] compass

[Jon Wallace via Personal_Submersibles]

Alan,
It's been a while, but I can report back now.  I just finished building a display for Hank using the CMPS12 sensor and it seems to be a good low cost alternative to the HMC6343.  I like the fact that it has an option for TTL serial communication and the tilt-compensation seems to be quite stable.  I wouldn't hesitate to purchase it and I'm going to get one for myself even though I already have the HMC6343.

Jon,I have to buy a compass some time so looked it up but it's pretty expensiveat $188-. I also saw a video on it dated 2010, so it's at least 8 years old.There are modules for less than $20- but not tilt compensated.It does say it is "high end" but is there much difference between a cheap& expensive compass? ( I know nothing about this).The thought came to mind that you could possibly cover it with resin &mount it outside the hull away from magnetic interference.Alan
