Yes, I use a RCAT glow driver. I've had it for about 5 or 6 years and it is the most useful piece of field equipment I own. The only problem is having to track it down from time to time at the field as all my friends love it too! I had the manufacturer increase the auto shut off time to 5 min so now it's even better for troubleshooting. Still on the original battery too. Expensive but worth every penny.
