Here comes the return of digital thermometer and Heater units. We were introduced to Heaters with digital read out before. You remember the bulky box with extra cords. It looked like you were dragging a octopus out of your tank!
Here is the newer improved version that will be bringing the digital read out of temp with heater on the other end of tube. A much nicer view. This will make the view of heater more desirable. This heater is fully submersible with quartz sleeve.
this is the smaller 100 watt version from Aquacave. There are 100 watt, 200 watt and 300 watt versions available now from Finnex.
