I'd be interested in how you think it compares to that ZNA you've got.
On many levels there's just no comparisom ; the ZNA is a much more highly engineered gadget, build quality at pretty much mil spec standards. It just feels far different that the usual PV. Easy to understand when in-hand. It exudes quality & precise manufacturing.
Had every intention of flipping the thing to essentially pay for the XPV ( crazy eBay prices ) but couldn't bring myself to do it ... I'll use it around the house mostly.
If the ZNA was made of aluminum & had usb charging, I'd buy the 18650 tube for it, a couple of battery's, & live happily ever after with only one device.
In practice ; the XPV
offers more ; it's got a big battery that lasts all day & beyond, micro usb charging, it's lighter ( albeit larger ), the pocket clip is actually quite useful. The XPV has a lot going for it to be sure.
It's a very nicely made utility kind of device & better to carry / travel with I believe.
But ...it is what it is ; a nice form factor project box with a full feature set.
It's a very nicely made tool, whereas the ZNA is engineering & manufacturing at an artistic level.
The nice thing about 'em both ; made in the USA. I like it when my money stays in this country.
