I have to be missing something. A few months ago I bought a pinpoint monitor with a new probe from someone here on RC. I couldn't get it to calibrate. The member said he never calibrated the new probe to the unit, but stated it was brand new. So I thought maybe I just got a bad probe, ordered a new one from Marine depot. Same problem, so then I suspected it was the actual monitor itself. I bought an aqua controller jr. NOW with BOTH probe I STILL cannot calibrate either of them to either the pinpoint or the aqua controller. I use battery power with the pinpoint because i read that the ac unit could cause interference. I took both units as far away from electrical interferences as my house will allow. The aqua controller jr and the latest probe are both brand new bought from reputable online sources. The monitor and other probe, the monitor is definitely used and 99.99% sure the probe was brand new when the other member sent it to me. I must not be using the probes correctly or something. It really feels like when you get some new electronic device and there is that little plastic tab you have to remove for the battery to contact the device so it will start working. Or better yet, there is a plastic cover on the probe that i need to take off. It feels like there is something like that that is really obvious but I am missing it. Please Help.

I have always used the Milwaukee probes. They come with a rubber piece on the end that protects the probe and keeps it moist when not in use. This must be removed. Other than that I don't know what could be causing the problem. After removing that cover I put the probe in the packets of calibrating solution and dial it in.
