My spark shuts off when I close the probe. It retails for $149.00 in the states. I did find one at Scheels the other day for $65.00. This must have been a mess up on their end. I purchased it, the last one they had. Later checked my receipt and found that they charged me 149 for it, but scanned it twice. After calling them and letting them know what it happened and that I was going to buy another one for my neighbor, they are mailing me a second one for the same price and adjusting my bill. I guess lightning strikes only once. I love my spark. It’s like pulling a Ferrari out to check what temperature your meat is running.
