XT Mini Lap Timer
I bought this in July I believe and used it for 2 track days so it's practically brand new. It does have a TINY scratch on the screen which is very minor but otherwise it's in as new condition.
See the link - they are selling now for anywhere from $110-$120USD ($130-$145CDN) plus shipping in most cases.
I'm upgrading to the Ultra lap timer and don't need two of them!
Anywhere that has a beacon in place this will work fine - it's accurate and requires ZERO installation - zap-strap and/or velcro onto your bike and you're set!
