I'm not sure that it would be allowed? But at this stage I really don't think it's a good idea anyway! I know all the arguments about GPS being the way forward ect, but I still think you really do need to learn the basic traditional skills first. They've served many of us very well for many years and can always be trusted as a back up to GPS if that is the way you eventually decide to go. If you carry a GPS at your stage of training, the temptation will be to use it and never really learn or have faith in traditional nav methods.
