I want to thank all of you for your sensible responses. The reason I was wondering about rechargeables is that while digging through an old box I have under the table, I came across a 9 volt battery charger that I'd forgot I had. I tried calling Tesoro in Arizona but I've been getting in so late from metal detecting at the rodeo grounds that the company was closed. Was going to ask them if it was feasible to use rechargeables. Most of my other detector instruction books state; use alkaline or rechargeable batteries. Tesoro says -use an alkaline - made me wonder. rmptr must have asked Tesoro at one time and gave me thier logical reason. Thank you rmptr for explaining this.
Tabdog. Thank you also for your response. I do use headphones - always have. I bought some quality phones from Kellyco. Used to always use the ones that came with the machine but got some Detector Pros. w/limiter and they work great. The use of phones is manditory because of nerve hearing loss and the firing of loud rifles. When I was young and shooting bench rest, I mistakingly thought I was tough and didn't need hearing protection. Nerve hearing loss runs in the family, but, loud rifles and my father's old D John Deere tractor I feel worsened my condition. I was too stupid to use ear protection. But thanks again, Tabdog, I know you have the best of intentions.
JHM. Thank you for your input. Very much appreciated. You must return and tell me where I can purchase those 9.6 batteries, I've never heard of them. They really sound great!
And you, Jabbo - you must be an engineer. Your mod looks great. I wouldn't dare try something like that. All though I'm a "Jack of all trades" electronics kind of baffle me. People sometimes baffle me also. I stopped in to see the dealer that I bought the Tesoro from and asked him about batteries. He said not to use rechargeables but didn't say why. He also stated to use only regular alkalines and not the heavy duty. When I inquired why - he said because the heavy duty and super duty were too hot and might disrupt the electronics. I went on the internet and typed into the search engine "Battery Facts". This article said that heavy duty and super duty was mostly hype and no stronger than the regular in about 90 % of the brands. Whom do you listen to? The prophet Isaiah told the Israelites - "Beat your swords into plow-shares and be at peace. Good logic. Ben Franklin said - "Those who beat thier swords into plow-shares, usually end up plowing for those who didn't". Good point. But whom do you listen to? Dimesworth
