GPX mAh usage???

[soky72]

I know this question is dependent on several factors such as coil size but what is a good estimate of the hourly mAh usage on the GPX? I've heard one person say in the 1000 range on an older minelab pulse.

From what I have read the GPX draws 750ma.

Thanks, was just curious because I was building a light battery setup and was using 3500 mah 18650 rechargeable batteries and was hoping to get 3 hours out them before switching them out. I've only run it once for 1.5 hrs and still showed almost 3/4 charged. I'll post the setup after running a bit longer.
