| My detector is a Bounty Hunter Pioneer 505 which takes two 9 volt batteries for it's power. I plan to use a single larger batter around 12 Vd/c to drive my unit instead of the two rinky dink little 9 volt batteries that drop too quickly for my confidence. | |

Before you go any further, check to see if your batteries are used in series in the detector. Remove your batteries. Using the very highest range (over 1Mohm, see if the terminals are shorted in any configuration from either positive terminal to either negative terminal. If one set of pos to neg terminals are reading a short, lower the range until you verify that they are shorted. Most detectors I know of that use two 9v batteries are actually using 18v internally to generate the proper voltages for their operational amplifiers which require split power supplies.
I'm guessing here but I believe the Bounty Hunter is no exception. Putting in two regulated 10v sources will indeed fry your detector if this is the case. Check it out before you continue.
Here's the good part. Some people use an external LiPo battery pack these days to replace the 18v source. Their capacity will beat the daylights our of the wimpy little 9v every day. You could also consider using two 8 cell AAA NiMh packs external with a 4 wire connector to the detector. Mount it on your hip with an easy disconnect (to prevent damage) so that the wire will pull out easily of your tug on it by accident. Modern AAA NiMh batteries have a capacity of over 10 times that of the 9v.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.
