So it is possible to disable the GPS signals from the Deeeper Pro + and use the GPS from the Iphone?
Correct. :)
Pro+ is the same device as Pro, but has the internal GPS-reciver. With both models you have a few modes to choose from and only one (shore-fishing mode) makes the Pro+ use the internal reciver. For all other modes it uses your phone or tablet. In this case I use boat-mode, so it uses my phones reciver and draws up the map. You could also use standard-mode where it uses the phones reciver but does not record any data or draw a map.
Due to the rather poor internal reciver in Pro+ I see no reason to buy Pro+ over Pro. Pro is however a lot better then the cheaper 3.0 that uses Bluetooth instead of WIFI and has the old sonar. The Bluetooth-signal has shorter range and is more unstable. The sonar in Pro/Pro+ is clearly better then 3.0.
