This SI timing-chip-in-a-compass is technically equivalent to the SI-10. It is built into a MosCompass base-plate so you do not need to carry both items with you. It works perfectly through multiple folds of a map, and is completely non-ferrous and thus does not affect the compass module.
Just hold the module over the timing chip hole to punch the control.
For help choosing the right SI timing chip for you, take a look at our blog post - How to Choose: SI Timing Chips
