Hi there, I have an 18 month old rescue Saluki cross Lurcher who I recently took out lamping just to see what his prey drive was like. I borrowed a friends rechargeable lamp that firstly was quite dim and secondly the battery only lasted about 20 minutes. My dog seemed to know exactly what to do we sited the rabbits got them on the lamp and he was gone. He chased them but missed several times (he still hasn't got one) But my question to you all is what lamp should I get? I will be lamping with him quite a bit but want to keep it as cheap as possible, battery life is my main concern! Any tips w
