I was wondering if this gauge has batteries in it that are changeable or not. I searched on here and found some were replaceable with a bit of effort. I have 2 of them, they are older units that I picked up with some other used gear last year. Also read that some are water/depth activated. These up to now have only been used in a friends pool and have not been deeper than 3-4 feet. How deep would they have to be submersed before activating if still good?
