Free: Contests & Raffles.
I much prefer my smart phone to the GPS. It can be a bit of a pain pre downloading the maps if you'll be in an area with no cell coverage but the downloadable area is huge.
In the field I always use a GPS. It's more weather resistant and durable than my phone, has better battery life and battery replacement is easier and cheaper, and if damaged is less expensive to replace. There's no online/offline to mess: turn it on, and it works.
I run a phone exclusively. Bigger screen, better image, don't have to spend a fortune on batteries, already carrying it into the field anyways. Put a good case on it and the odds of breaking it are probably no better than breaking a handheld gps (no doubt a GPS unit is mlre stout though).
Rino. When I have the big one out there, it'll be nice to key the mic so they know where to find the body.
Phone with inreach backup. Picked up a luci solar light that recharges my phone to 50% when the solar charge is full, more if you use it in the sun. I keep my phone on airplane mode and 50% charge is a lot more than i need for a days use. Have used rhinos but unless everyone has the higher wattage ones they are basically just a gps with a small screen in mountainous terrain.
I put my cell phone in the life saving category. I want max battery and for it to be used as communication only. USB chargers can die, it might be left at the tent/truck, cord my not work or get lost and if you've been using your phone exploring a whole new area, marking points, and only a few miles from the truck with cell phone service, you slip and fall and become immobile and realize you have 1% battery left, you probably aren't going to be able to call for help. And yes, I also carry an InReach as a backup communicator. And don't have the InReach+ for the same reasons, that I want a dedicated GPS, a dedicated Phone, and a dedicated Sat communicator.That is my world....hopefully you aren't as crazy as me though and can find a better balance! I exclusively use my GPS, it's not much hassle to load KML files from BaseCamp to OnX for checking out online or your app when back in the city/home/work or from OnX to Basecamp to keep them synced.Outside of the woods, I use OnX almost daily online and sometimes on my phone.
Might be a dumb question, but if you exclusively use your smart phone and the OnX app, what do you do for actually dropping pins for a trail you've taken or so you know where you are on a map? The areas I hunt there is virtually no cell service. Just curious as I know with a Rhino it will pin point your position.
