I agree with Barklydave. One other thing to check is the meter. Put your Fluke on mV and go from the sensor to the hull. It will be much more accurate than the meter in the boat. If you find it to be off, I would find the true reading with the Fluke and then set the meter in the boat to read the same when you press the button. Then it is accurate there for that reading. I would not set the needle to zero when you are not pressing the button. That would only make it correct when you are not using it.

Seeing you are in fresh water, magnesium is the only way to go! I had a block of it bolted to the top of my trim tabs. Got great readings for many years as it was slowly used up.

Your readings are fine. This time of year water is cold and less sediment algae etc. Numbers will move up. I would not recommend a second Mag. One is plenty. You may also find better continuity by clamping to a stantion. Check with OHM meter to verify continuity.

I'm glad to see y'all saying his CAPAC reading is fine. Mine fluctuates from 0.6 to 0.9 all the time. Everytime I see 0.6 I get nightmares of my props falling off and the bottom of my boat rotting out.

Did they also mention 6 weeks lead time?
When I contacted them a few months back the lady I spoke with said there was a six week lead time on them.
I had originally tried to contact Ward's Marine with no reply for months from them, even posted on their FB page without getting a reply, finally I started a dial-fest between the two locations and at last got to a person, they said they had a few (or a couple?, I don't recall now) in stock and quoted the $700.00+ price.
I understand now why someone stole mine, I've searched for a few marine junkyards and most of them say they don't have any new or used.

Busia wrote:Wow! $500 for the meter! Yes, this is just a little electrical cell " battery" you are making with the hull and sensor, with the water as the electrolyte. Go to boatzincs.com to read and learn all about this. Best prices and service when you want to buy anodes. They have a test electrode for $125 and get a $10 VOM and you have the same thing. I put a new bottom on my boat and got rid of all the holes I could. I removed the sensor and now just hang it over the side with my VOM set to mV in series with the sensor and the hull. --Ed
Are you aware of where I can get instructions on making a home made sensor?

The actual sensor you will probably have to buy. I believe it is silver/silver chloride. Don't know of any homemade ones. You could call boatzincs.com and talk to them.
