i lamp on foot but a mainly lamp off back of van i think it gets u a bigger bag u cover a lot more ground and where i live if you just walked u wouldnt get that big of a bag!!!
lamping off the backoff the van is brilliant in my eyes and is no way lazy as when you see somthing you jump off the van and walk up to itwith the dogs it saves time and gets the dogs more graft in my eyes!!!
