After reading RedLeg's Rides, I also purchased a voltmeter for a couple of my bikes. Putting a voltmeter on the bikes has been on my list for a while, but I haven't gotten around to it yet. I am running a lot of heated gear lately and it would be wise to keep an eye on the battery. I decided to be lazy, so I copied him and bought the same one he did. He has the same requirements and goals I do, so it should work out fine. I purchased the XScorpion DVM3R from ebay for $20 after shipping. Thanks Domingo!
