Typically Hollis quality


from minneapolis, MN, US

Excellent gauge large easy to read highly recommended


hollis spg


solid and well built, easy no nonsense display that is easily read at any depth or lighting condition, perfect for technical divers or recreational divers that want to streamline their rig and perfect for anyone wanting a back-up gauge for their wireless computer


Accurate and small


The red marked scale below 50 bar is only in good light conditions readable because the gauge needle is not fluorescent but black. I checked pressure accuracy against my Suunto D9 - great accuracy within +/- 3 bar, even at lower pressure.
