Please refer to the following chart for fuse size, power cable extension requirements and the current draw for our Fish Finders and powered accessories.
- In-line fuses are preferred to be glass "Slow Blow" or the MDL equivalent.
- Blade style fuses are also acceptable.
- 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.
