    9v Bounty Hunter modded to AA's

    Modded this Bounty Hunter Pioneer 202 conversion from 2 x 9v to 2 6xAA's. I have put about 10 hours on this setup. It is heavier, made from PVC pipe and fittings, so I lengthened the stem 2 clicks, about 3 inches, to get better balance and have been using a bungee cord to chest harness, that removes much of the weight, even prior to the conversion. I can still use 9v batteries, but likely won't as they are so much more expensive than the AA's. I'm guessing that I will get 90 - 120 hours off this set of AA batteries before they need replacing.

    Cool modification!

    However, do you really need the 2x 6AA cells? AA cells can delivery far more current than a 9V battery can. You can probably have a 6AA setup up deliver enough current to make up for the parallel 9V batteries (I assume the Bounty Hunter's 9V cells are run in parallel and not series).

    EDIT: To save even more money, try running some NiMH cells (like Eneloops) in those 6AA battery holders. The voltage would be a little lower than 9V, but I imagine it would still work.

    For added weight savings, you could probably get by using a single 6AAA (not AA) battery holder to provide power for the entire machine, no problem.

    I run all my electronics on AA cells, just makes logistics easier, and AA's are the most commonly available battery in the world, which is a concern when I am out of country and in a 3rd world location.

    Bounty Hunters have 2 separate circuits that are run by the 2 9v batteries http://www.treasurenet.com/forums/metal-detector-modifications/536927-battery-swap.html
