Not a true equivalent, as it's $40 more expensive, and is missing a $200 salinity probe.Here is the equivalent in the newer A3 model which is not discontinued.

I don’t think the price increased much. You just lost a salinity probe and picked up some water sensors.A3 Replaced it for a hefty price increase....

That’s called good business!Geez I didn’t realize a salinity probe cost that much. It doesn’t work well enough to warrant that price.Not a true equivalent, as it's $40 more expensive, and is missing a $200 salinity probe.
$240 price difference... That's a 28% increase.I don’t think the price increased much. You just lost a salinity probe and picked up some water sensors.
I know what you are sayingGeez I didn’t realize a salinity probe cost that much. It doesn’t work well enough to warrant that price.
It’s still the equivalent in the sense that it’s their highest end model.
... I am just being grumpy... I opened the box last week to find Salinity missing... they didn't even change the mold, it's the same mold with an empty spot.Actually I just added up the things that are new to replace the salinity probe and you get the functionality of a FMM ($105), a lls ($60) and a leak sensor ($40). So actually cost wise it’s didn’t increase that much.$240 price difference... That's a 28% increase.
Never had an issue with my salinity probe on my other system, not sure what folks do to their to make it not work.People really care the salinity probe is missing? The probe that constantly has issues and wasn’t in stock for like 2 years?
The new sensors and added FMM are 100x better than a salinity probe. If your salinity is changing enough to warrant a probe to monitor it, you got bigger issues on your hands
Or fleecing someone over the coals.Have to discontinue it so if people want a salinity probe they pay the $200That’s called good business!
For those of us that have a ffm already, meh... I mean let's be real, the modules are overpriced for the most part.Actually I just added up the things that are new to replace the salinity probe and you get the functionality of a FMM ($105), a lls ($60) and a leak sensor ($40).

Agreed. I just bought my first Apex… A3 pro and considering what others have said about the salinity probe and the new liquid level sensor… I like the new set up better. Glad I didn’t buy the older model.People really care the salinity probe is missing? The probe that constantly has issues and wasn’t in stock for like 2 years?

All of it is overpriced IMHO. I’m just glad that I got mine when it was $600 for the full model because I wouldn’t be willing to pay the $900 that it costs now.For those of us that have a ffm already, meh... I mean let's be real, the modules are overpriced for the most part.
Now the salinity probe cost increase, that's a crock.
Back when I bought the PM2 and salinity probe, early 2019.All of it is overpriced IMHO. I’m just glad that I got mine when it was $600 for the full model because I wouldn’t be willing to pay the $900 that it costs now.
How much did the salinity probe used to cost? I don’t remember but I wasn’t thinking it was even close to $200. For that cost there is no chance I will replace mine when it eventually fails.
