Why a second DCP reading is refused
The app keeps one DCP reading for each depth. Here is what to do when it says a reading already exists.
You may see this message on the Depth (m) field:
Why
A DCP chart has one bar for each depth. Two readings at the same depth would draw two bars on top of each other, and the log would not know which one is right. So the app keeps one reading for each depth.
The rule also protects you from a weak signal. If your phone sends a reading twice, the second copy is refused. You do not get a duplicate.
What to do
- You meant a new depth. Change Depth (m). For example, use 0.4 and not 0.3.
- You want to change the old reading. Find it in the DCP list and press its edit button. Change the Blows or the other fields.
- The old reading is wrong. Delete it from the list, then add the new one.
If you still cannot add the reading, contact support.
