I have the camo LS model. I was wondering if when the batteries start to weaken if my detector's detection power weakens also? Seems like i fined more when i have full batteries. I also have recently bought rechareable batteries. Does any one else use them and how well do they hold up compared to throw aways? I just started using them today. Used them for about 30 minutes. When i switched to the new batteries is when i noticed for some reason I started finding alot more coin. Wonder if it was just coincidence?
