So I had a chance to do the ice water + boiling water test and this is what I learned.
I did the test in Celsius since it was easier to remember 0C and 100C. Both the Maverick and the Dog came within 2-3C of each other for both ice water and boiling water. I stuck it in ice water then boiled then ice water and boiled again then ice watered a final time. It took about 1 minute for it to reach the correct temp. The difference came in how fast they registered the temp drops but it didnt seem to affect it as much when the temp rose. I noticed the Dog registered temp drops at a much slower rate but eventually all probes settled at the correct temp. I did not change the PB setting on the Dog for this test.
I think one or two more cooks with it and I should be able to write a conclusive final review.
