I have an Ole Yeller myself. You will be completely happy with it for now. I do not have your youth so I needed help getting the coodinates in the puter. My 38 Y/O fingers got tired of manually entering then in. You will in the future want the cord to hook up to the puter and download coordinates in a flash. I was able to find one at Gander mountain, but then you pay their price. Off brand cord can be purchasd online for much less than I paid, But I wanted it now!!!!!!! you know how that is. As far a battery life goes I have found that regular alkaline batteries last much longer that rechargable nickel cadium or the other kind. Lets comare a couple of full days of caching to an after noon of it with the rechargeables. It is a fine unit for the price I am now just thiking that a built in map would be nice for driving. But you have a bit of time before you need to worry about that. Enjoy.....
