Fuse Size, Power Draw and Power Cable Extension Requirements

Please refer to the following chart for fuse size, power cable extension requirements and the current draw for our Fish Finders and powered accessories.

  • Fuses are to be "Slow Blow" or the MDL equivalent.
  • Wire gauge for power cable extension is listed according to length desired.
  • Current Draw on a low battery will be higher than listed.
  • Current Draw while on a charger and when the engine is running could be less than listed.
