Great review. Probably sealing the deal for this product. I started kayak fishing in July, 2022. Adding a Garmin Striker 4 Vivid CSV for Christmas and was looking for power sources. This has everything I want and can be transferred to another kayak, should I upgrade, pretty easily. About to watch your install video next. Thanks again.
It depends on the fish finder. My Garmin Striker vivid 4cv has a power source voltage range of 10-20 volts. So in that case I don't need it. But if you need an exact 12 volts for your fish finder then yes you will need it.
