Not a problem. I am ordering it this week so I will let you know pretty soon.
I am leaning towards the RKE since there some differences but the warranty is 2 years for the units and 1 yr for the temp probe, 90 days for other probes. For Apex it is 1 yr for units and 90 days for probes. That coupled with the online support and ato bargain I will probably get the rke. And they finally seemed to get a working salinity probe.
Thank you Carey I will send you detailed information once the rke arrives.
