Got a good question from a guy today: “…wondering the best way to identify, conquer and quit digging aluminum can slaw, its spread all over on some park sites near my home.”
This is a good question to illustrate the value of developing broad based target testing skills–even if you don’t use them all the time. While there are some situations where a quick “hear and dig” strategy is best–where you have a single problem target taking up your time look for characteristics that will cue you in to these objects. For example with suspect “can slaw” use the cross sweep to look for inconsistent meter and audio readings. With the Equinox, using “50 Tones” can help to bring up these multiple sounds. As well, look for a similar meter reading. This can depend upon the size these pieces are being shredded to. Single reoccurring numbers will often be present as the machine “cycles” though. Lastly, watch the depth meter. These will always be surface targets. You can also just move to another area in that sometimes a single can will have been “mowed” over. The important principle here is to combine knowing specific target characteristics with general principles to form a complete picture of what a questionable target is–rather than just hearing a solid tone, seeing a meter reading in the middle range and digging automatically. Taking a few of these targets home to test can give you a more complete picture of how they respond: tone, meter and consistency. Then combine this with your understanding of the site itself. Not paying attention to what the machine is (or could be) telling me is a mistake I still make continually after 40 years of digging–never hurts to be reminded!
