During the recent CV19 lockdown it became obvious to me that i needed to become more self sufficient in all matters of survival and most importantly my airguns needed an unlimited air supply. So after much studying and research i decided on the Daystate Type 2 compressor ... i did struggle to find a good informative video so to help others and to answer any questions on the subject here is a "how to" video while filling my dive bottle from around 200bar to just over 300bar ... any questions please fire away, thumbs up or down appreciated and please feel free to subscribe.
