I want to by a new digital thermometer. I am familiar with the Maverick ones and have Looked around Amazon for reviews. Here are my questions : 1. Is there one out there that will read from a "below zero" temp to over 500 deg? - I am looking for wide range of use. 2. Is a budget of 50-60.00 realistic if not looking for "long range" or one that uses apps on my phone ? - want a basic/ reliable model. 3. Lastly, is there one that can "monitor" at temp alone? - I hate the fact on the ones I have currently that I have to set a high/ low setting every time I use them. I just want to monitor. I am open to other models and types.
