This isn't 'portable' at all. I bought it for my kayak and stupid me didn't read all the reviews. First, it needs a 12v battery...or you can buy a nocqua battery pack for an extra $90+ with additional cables ($20). The mount doesn't have suction and can't be mounted to a kayak without purchasing additional mounting brackets ($35+). The screen isn't waterproof and doesn't appear to be well suited for taking out into saltwater where it may get splashed. It may be perfect for some pond fishing, but that's about it. All in, you'll spend over $240+ for this to get it powered and mounted. Needless to say, I returned mine.
