trust me, my feet hurt from standing and watching the temp go up down. i am so glad to here a reply from you. i trust your advice 110 percent. so just get a average between the two temps. sounds great to me. i belive i am close enough on temp range.

An incubator by nature has to raise and lower it's *air* temperature. Think about it....temperature warms to a pre-set degree and the incubator turns off...then the thermostat cools to a pre-set degree and the incubator turns back on. During this time the eggs' internal temperatures are not changing very much at all during these short cycles...BUT, the air temperature IS changing. If you don't have the probe buried in a water wiggler then the Brinsea is reading the changing/cycling air temperature and not the constant internal egg temperature.

It is much like the central heating and cooling in a house. The system turns on, the fan starts to blow hot (or cool) air. You feel this blown air and it's either very warm or very cool...it's *several* degrees warmer or cooler than the temperature that you've got the thermostat set on. When it warms/cools the thermostat to the pre-set temperature it turns off, the warmer/cooler blown air stops blowing and the ambient temperature is close to what you selected via the thermostat. As the ambient temperature begins to cool off or warm up the cycle starts over again. During all of this cycling if you had a glass of water sitting on a table it would reach a fairly constant internal temperature while the air around the glass continued to fluctuate a bit in the process. You can't tell the actual temperature of the water by reading the air temperature....thus in the case of egg incubation, if you wanted the actual egg temperature then you would have to use something like the water wiggler with the thermometer probe inside of it.

Clear as mud, eh?

i agree. my problem is getting familar with a very accurate thermometer, the walmart junk i have been using is very slow to read changing temps. they were alot easier though to pre set the bator temp. this spot check reads so accurate, i was wearing the knob out trying set it to 99.5. i dont have a water wiggler yet, but i feel like i will get a more stable reading that way. instead of it reading the changing air temp. up and down. aslo as speckeld hen pointed out i just need to stay in the comfort zone of say 90 to 101. hopefully the water wiggler will give alot stable temp like i am used to seeing from a thermometer. thanks everyone very much.
