Not only that but you would have decay time issues also your coil could become a heater, you don't need much power to have a good detector what you need is to be able to see the return signal (eddy currents) a lot of people think more power = more depth and yes to a point that is true BUT now have new problems lots of new problems like I mentioned the decay time, also you could end up detecting the ground minerals or just the magnetic field that you put into the ground, that is why the PI detector like the DBP2010 runs at 90 PPS to allow for everything to settle down before you start to do the sampling. Designing a detector is hard work and lots of frustration because you need to have everything well balanced, the coil needs to work for the electronics and not the other way round. A lot of people here will tell you to make the coil then build the electronics around it because it works, why do you think that it's so hard to make a coil for a detector that works? if you do not have the specs for the coil your schematic is worth zip that's the bottom line.
