Hi
@Rearviewmirror
I've had 2 antenna failures. I discussed the topic with Richard at Dive-Tronix. Apparently, most antenna failures are thought to be due to trauma, as the connection of the antenna to the circuit board is/was tenuous. Neither of my Terics had any trauma, just abruptly quit working.
Got my Teric in November 2020, no issues with it - works beautifully! Just a positive comment to offset (a little) the poor experiences others have had.

I rinse my Teric is water that is room temperature or just slightly above.
Good luck with your replacement Teric. Have you voted in the other Teric thread, link above?
