Tracking is what I do when I am not online for the last 24 years. You get what you pay for, especially when stolen.
There are many many different products on the market, some are cheap as chips, some way overpriced.
Depending on the boat and engines especially in the western cape, a lot of the time you come outside only to find your boat no longer has any engines on but the boat is still there, often the boat is found discarded somewhere and the engines and electronics are gone.
It really depends on what you want to do, where are you located, in other words Northern KZN chances are your boat is going to Moz so you might need something with roaming. What is the value of the boat, value of the engines, have you got the newest top of the range set of Mercury Verado's on the back?
Lots of questions. For example i drive a cheap chev aveo, i have no intention of seeing where my vehicle is, i only want to know where it is if it is stolen. I pay a monthly fee of R106, have national recovery, no installation costs, no electrical wiring, no software.
Upside is if you do choose something that is approved by the insurance industry, you are very likely to get a nice discount on your current insurance costs.
