Like all the Goal Zero products I have used in the past I was very impress with the performance and quality.
Most importantly for me is that it kept my battery full and my fish finder on my kayak working all day long.
This is so important for me when doing remote trips as I have a fish finder and bait tank running on 12V batteries that I must keep up and running for days at at time.
The Guardian 12v charge controller is the perfect fit for me while shooting episodes of The Kayak Fishing show.

Besides the Guardian's ease of use, I found it to be made of quality materials which seem to be rugged enough to endure the harsh climates I often find myself. Goal Zero's Guardian uses the sun to provide a maintenance charge to your batteries and is easy to use. I can now maintain my batteries while at home or in the field without having to use electricity!

I was able to attach the Guardian to my vehicle and my battery in less than 5 minutes and my vehicle has been starting steady for the last year with no more dead batteries, even when I didn't drive my vehicle for weeks and even months. The Guardian product was a successful solution to my power problem and has been the easiest way I have found to provide my vehicle with a consistent power charge. Now, when I am out camping in the mountains and I leave the lights on in my vehicle for too long, I will never be stranded as my vehicle will always be able to charge when there is sunlight available.

On opening day you won't be dead in the driveway or – worse – on the water.
