This is the GPX Timing Sticker that can peal off and stick to any surface. Many will stick this sticker on the upper shaft as referrence to the timings when needed. This timing sticker is a huge help on both the Minelab GPX 4800 and GPX 5000. It list all the timings, 8 of them in total and explains where they work best (non-mineralized to high mineralization). It also explains on how much depth each timing will get.
A must have for any Minelab GPX 4800 or GPX 5000 owner.
