Since my R/R left me stranded when I replace it I'm going to install a voltmeter as well. I like the looks of the Datel DMS-20PC-1-DMS, especially flush mounted with the bezel. The vendor says that it is splash proof and will work in motorcycle applications. Does anyone have any good or bad experiences with this model? I have seen the C-Volt and it is advertised as waterproof, but like the looks of the Datel better.
