The Apex EL is missing 3 things vs it's big brother the Apex WIFI Gold ($799)

The Apex EL does not have the ability to measure salinity native. It's missing the salinity port & probe. These can be added at a later time by purchasing a PM2 Module & Salinity/Conductivity Probe.
The Apex EL is missing the 0-10v port which allows the apex to control external devices like Kessil LED's, Vario Pumps, etc. This can be added later by using a VDM Module.
The Apex El is also missing the ORP port & ORP Probe. These can be added later by using a PM1 Module & Probe.

So there you have it. The apex EL is exactly the same as it's big brother except for the 3 things missing above, all which can be added at anytime by purchasing a module and/or probe.
