I think Darryl was trying to suggest a back-up logger to avoid the
emotional drama that goes with when the electrons screw your ass,
taking one out of the "racing zone" not to mention kill the fun of
drinking beer and listening to all the great day stories.
Trust me when I say how good it is to say, " Oh really, here's my back-
up scorekeeper. Would you like a beer while I get me another one?"
I use a CAI M25 black box that I have rigged for back-up navigation
that cost 800$ and will always cost 800$ when my heirs sell it. It has
yet to burp, simply records , and regurgitate on demand.
Don't get me started on spare tire tubes.
