Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I have a chance to buy someones setup and will find myself selling that tank to get most of my money back, but it will allow me to have an Apex system with some probes. But I am sure it is a classic system, as his set up seems a little older.
I have a classic that's four years old that works perfectly fine only difference between the new one and the old one, is the new one is Wi-Fi and has power monitoring and will work with the trident. If you don't care about the trident then a classic will be fine.
