hi bryan,am finally moving on from the old mk 1 system was wondering which system was best for me. i,m not an all out digging man but do my bit .also work cover and blocks of forestry. is there a system i could use to ground and use while hunting cover with multiple collars. also could you give me a price list and a bit of a breakdown of pros and cons of the various systems as price unfortunatly is a factor for me. thank you. input from anyone else more than appreciated. border man
