darn temps and thermostat

What do you think about the GCS 4 probe proportional tstat?

None of my tanks will be identical, and it can get mighty expensive buying a proportional tstat for each cage!

i have not personally used this so i can't say either way. i have had success with the rancos and the johnsons. but my room is also very stable and is also digitally regulated by a thermostat and also a humidifier. i have never heard anything bad about helix and alot of breeders use them. by the way i also work in the hvac industry and i'm a little anal about my room and temps i thik that has alot to do with my success with the rancos and the johnsons. helix is proportional and that is better for maintaining a steady temp. especially if the tanks are not in very stable rooms. the other thermostats operate on a one deg differential at best. the proportional thermostats operate around 1/4 th deg. differential. the temps do not have to move a deg to cycle the control on and off, the heat remains steady to maintain selected temps. i knopw the helix can display a tenth of a deg. but the display is seperate from the operating and sensor. 1/4th deg is plenty that is all a thermostat will need for any of our purposes.

I have heard good things about the Spyder Robotics Herpstat, but haven't used it myself. I'm currently debating on whether to get one of those, a Helix 1000, or 1001.

All will yield consistant temps, proportional will be more consistant with a room temp that is not stable. If you plan on using the same heating element than go with the Herpstat(spyder robotics). If you are gooing to have different elements than I would reccommend using more tstats or going with the GCS.
