Hello fella's,
Diesel, the kit cost $65.
The generator board I have will power 2 x 50W transducers for 5 mins on, 5 mins off to cool down, I will install a 12V computer fan to keep it cooler and increase run time, maybe.
It will have its limitations.
You can have as many transducers as you like, but you will need a generator board that can power them. The price for those goes up.
Trev, I am not having a heater at all.
I have never used one of these before, so I will see how it goes using hot water from the tap.
Hopefully it will turn out to be something I can use. Cheers
