Apex PMK experience

[Pat H.]

Anyone have any experience with the Neptune Apex PMK? It looks like a better/cheaper alternative to buying an Apogee model to me. I’m curious about accuracy and longevity.

While I’ve not personally used it, keep in mind that the Apex takes sensor readings at a maximum of once per minute. So with the Apogee, you can get a read in a spot and immediately move to the next area and get a reading, while the PMK will take a reading, wait 60s, take another reading, wait 60s, etc. The PMK is more useful for mapping par in one spot throughout the day or over a longer period of time, whereas the Apogee is better for mapping the whole tank.

Sorry, I don’t have any experience with accuracy or longevity, but I’ve seen them pop up for sale a few times on the site, so hopefully someone here who has used it can chime in.

Thanks for the info. I wasn’t aware about the Apex update rate.
