Just be sure you know the product. From what I've seen there are 2 types.
1 - button like tags, these are only good for tracking as long as they are within wifi range. So if you boat gets stolen and stored/moved away from an open/unsecure wifi network, you can't track it.
2 - mobile network trackers, these are a small hand sized box that usually has constant 12v supply. They can incorporate an old mobile phone or a SIM card. These ones you can track as long as they are powered up. And you have to pay another monthly phone bill.
Me, I can't be stuffed with either, I just fit a trailer lock and park it all behind a gate for the honest thief and pay insurance because of no hoper scumbags.
