GPS Navigation and Trap Tracking App specifically for Crawfishing

Designed for the special uses for Crawfish/Spiny lobster fishing to aid in recording trap/condo locations, and for navigating to the condos for fishing.

Features Include:

  • - Adding Trap locations
  • - Creating Areas of multiple traps organized by most efficient sequence.
  • - Navigating from trap to trap by the ordered area.
  • - Recording and displaying a tracklog of the area being searched so you don't search over the same track.
  • - Recording historical locations for a trap in order to anticipate its location in the future.
  • - Record the condition of each trap to help determine repairs needed or whether the trap has been found on the last search. Helps to make decisions on which traps to fish.
  • - Record the catch count for each visit and rate the quality of the catches from colour-coded "Hot" to "Cold".
  • - Automatic backup to SD-Card to protect data in case of device failure.
Note that this App is the single-use edition of the commercial Crawfisher PRO app. If you manage multiple boats and require the need to merge all of the data from each dive boat, please contact us about the PRO version of Crawfisher at
