I upgraded my Apex to the full version and am selling my Apex Lite unit with display and temp probe. You will need to buy your own Energy Bar 4 or 8 to run it with your system. I'll throw in a pH probe but not sure how long its been in storage as it came with my full version Apex I bought. I have already upgraded it to the newest firmware version, 4.20.
**Repeat, you will need to buy your own EB4 or EB8 to run/control powered accessories with it ...otherwise, you will only be able to monitor temp and pH and thats no fun. :-)
PM is key. Thanks. $175, cash. PENDING
