Adactus is a really great store when it comes to gps and other electronics like cables and stuff like that. they've also got some gps antennas that could be really useful if you're going to install a gps on your car or boat or stuff like that. I've used them a lot of times before when I do stuff like this. The gps I've got on my boat and the antenna for that one come from this company so that's really great I have to say. I'm really satisfied with the quality that they've got on this store so I can really recommend it I have to say. They've got an online store as well which is worth checking out as well.
