Hi guys!
I'm going to camp with my family next month for a week or so. We want to make a camp with tents, campfire, fishing and so on

I'm a big BBQ lover, but an eater, not a maker

. We're going to grill some meat, but I have no experience with a charcoal grilling. (I use only an electric grill).
I surfed the internet looking for some tips on grilling and found an article about this stuff where were mentioned meat thermometers. I have no experience in grilling meat, so I think this device will be good for me. I'd like to get your wise and experienced advice on that. Currently, choosing out from
this page. Which one fits better for my case? I discovered that there are 2 types of thermometers: leave-in and instant-read which one is better for nonprofessional grill-maker?
