Puck Pro EZ as backup?

[hancockks]

I see there's a new Puck that uses ZH-L16C. I wonder how well it would match my Shearwater as an inexpensive backup. Anyone have experience? Seems the Puck 4 also uses ZH-L16C.

No experience, but there's no reason it shouldn't work. You will need to decide what to do about matching the gradient factors with your Shearwater.

From the manual:

"This is where you set the conservatism level
of the ZH-L16C algorithm via gradient factors.
The default value is R0 (85/85). If you want to
make the computer more conservative, choose
R2 (60/70)."

Of course, you can use custom GFs on your Shearwater to exactly match it. But if it were me, I'd stick with whatever you are currently doing and leave the Puck at 85/85 to avoid any deco issues when it's being used as a backup. If you think 85/85 is too risky, then just stay away well away from NDL on the dive where you need to press it into service.
