I’m old and don’t like change, and I’m happier than a pig in mud with my old technology ReefKeeper 2 controllers. I now have three of them, and they suit my needs just fine……until picking up my last one. The first two RK-2’s had nice metal (probably bimetallic) temperature probes that are as stable as stable could be. This last one has what they call an i-temp probe that looks more like a pH probe with a glass frit bulb at the end. I DON’T LIKE IT! I want my good old metal one for this RK-2 as well. Why did they change these. Metal is submersible and indestructible. This glass one is, well, not! Here’s the newer “old” style probe (that is listed for herpetology) (The old ones I have actually have silvery metal ends on them):
And here it the “new” i-temp probe:
