Ironically it has all the features one could wish for in the AT series sans waterproofing, yet cheaper. This detector has more features than the Vanquish and considerably more than the Simplex. Why would one buy an AT series with the Apex on board ? The Apex has some abilities the Nox 600 doesn't have.
Should have obliged me on my bet. LOL. Though I would argue this is a considerable upgrade over an AT. Just cheaper.
I'm guessing the "AT Apex" will have more powerful features than just waterproofing.
