well i have 4 different tubs in my rack going, and well I know to put the thermostat probe directly on the flexwatt and have all the flexwatt pluged into the thermostat so those will all be the same temp. But to check the temp inside the tub i only have one acurite and it seems as tho it may not be correct but thats not my problem. how do i go about checking the ambient temp(in the tub) because i dont want to use the same probe with all the snakes due to obvious reasons. and i know there is an easier way to check all the temps then having to go out and buy a thermometer for each one. i just dont know what the easier way is. PLEASE HELP!!!!!!!!!!!!!!!!!!

Thank you in advance...

P.S i just got a couple new snakes I'll put up some pictures in a bit.
