A stand alone GPS would do the same functions with a lot more applications than installed in a detector. You can mark a spot where you got a hit, it leaves a track or “Breadcrumb” trail you can color code mark spots, and pix for research later. Price point add another $grand for one w with a GPS.
The biggest plus would be the mapping. I use my phone with GAIA mapping software, Premium which is about $50/ yr. It gives me over 50-75 maps, new topos, old topos, USFS, NAV Charts, mineral veins, mine sites, Gaia Overland, and many many more to fit any need. The phone is linked via Bluetooth to a Garmin GLO ll GPS, so I don’t need cell svc. If I am in cell svc I even have Google Earth real time, so I can literally watch myself walking thru the woods on the screen. Then I can overlay a 100 year old Topo over the Google earth and off I go. Its like walking back in time.
Before I go on a hunt I will do hrs and hrs of research looking at old topos, maps, whatever. Figure out the lon and lat then load the locations into the Phone/GPS. During the hunt I will mark points of interest, and load a pix later for research. 90% success rate. GPS is my main tool in the arsenal. Don’t leave home without it!
I used to sell GPS units and do seminars where I used to work so if anyone have any questions give me a shout.
