This for lighting with the TG 6 and the only light source used. £31 for two from Amazon. Only 2 inches long and recharchable with USB magnetic end cap.. Well very surpised with the results done in a rush on digging day.
A big drop in May water level now 2.5m below the marker. 55mm of rain in May but the drop more related to the spring leaf growth as last year. This year in orange.
