Mike,
I have a question and wasn't able to find it in your thread, what off road GPS system do you use, and if you were to purchase a new one would you buy the same? I would appreciate any feedback you could offer.

Funny you asked this JB as I've recently switched over.
I have run Back Country Navigator Pro or the past several years. It worked ok for the most part and was relatively inexpensive as it's a one time subscription for the app. I purchased it mainly because that is what both of our Jeep clubs were using at the time and there were some knowledgeable people who I could ask questions about but it wasn't as user friendly as I wanted as I'm somewhat technologically challenged and want easy, especially when out on the trials.
Unfortunately over the past year or so I have found two shortcomings with Back Country Navigator. First is the person who developed it has done nothing new to it or updates so it's not progressing or improving. I've heard he moved on to something else and you can tell by the lack of support for the features. Secondly the topo maps that upload to it can be overpowering when using it for quick glancing on the trail (again, I like easy to use and view). Sometimes what you think you're following as the trail is actually a ridge line on the topo map. I discovered that on a couple of trails what I thought was a turn was actually a ridgeline and had to recorrect. It wasn't a big deal because it was easily caught but it has happened a couple of times to me. The only time it was problematic was when I was leading about a dozen Jeeps and had to find a place to turn us all around, plus I felt like an idiot. That will usually only happen on trails that are out in the open with no actual roads such as in a rock garden or Moab slickrock as otherwise the trail/tracks are very obvious.
What I found last fall in Moab is many of our group had switched over to GAIA GPS. I downloaded the free app to my phone and played with it while we were there and quickly liked the features. After doing more research and investigating I thought I'd try the GAIA GPS Premium version, it's about $39/year but many times you can find discounts getting it around $30-$32 per year. It is a few dollars but as much as we use it I personally find the features and ease of use well worth the money spent. If you are only looking for a one time trail or use it may not be of benefit but we go on multiple Jeep gatherings/rallies each year and the ability to download tracks prior to the event are great.
I really like the GAIA GPS Premium version as there are so many features such as ability to upload multiple map layers and on the fly fade various layers into the background, turn them off or magnify them depending on what you are looking for at the time. I also like how easily it is to share tracks with other people. I recorded a track while on a run in Spearfish, SD last month and one of the club members sent out an email asking if anyone had that track because we weren't following one at the time as we were just out exploring. I had turned on the record button while we were driving and even marked a few waypoints such as an old cemetery, an old mine and a nice lunch spot which could hold about a dozen Jeeps without blocking the trail. I was able to share the track with them easily via email.
The thing that makes GAIA GPS so nice is that it is a cloud based format (I know, no one understands the cloud

). You can do all of your pre-trip planning on your home PC such as uploading pre-recorded tracks, upload any map layer or multiple map layers or create a track and then when you save it to the cloud it is available to any device that you have the app loaded onto. That feature alone is awesome, I have various areas saved to specific folders than when we are going to wheel in an area I simply grab the specific folder that I need and it pulls it to my tablet. Once out on the trail and I have no internet I can add waypoints, take pictures and post to those waypoints or make comments at various points around the track and then when we get back to camp or home and have internet access it will automatically save it to the cloud so it will all be available next time or if you wish to share the track with someone.
I've also heard that some like Locust app as a trail navigation system but to be honest, I am so happy with the GAIA GPS Premium version that I'm just going to keep that one and become more efficient at it. I've imported everything I had on Back Country Navigator over to GAIA GPS now and deleted the Back Country App from my devices.
What's funny is we get together as a Jeep club and run trails and everyone thinks their version is the best and whatever someone else is using is junk. Same with radios, I was getting so frustrated during our Spearfish gathering because the club bylaws state each Jeep on the trail is to be equipped with certain items, a CB is one of those. Yet we had a bunch of people who insisted on using HAM radios and GMRS radios and many were getting confused as we had multiple radios and multiple conversations going on. During a night run the leader insisted on using his HAM radio but only he and a couple others actually had HAM radios, the remainder of us had CB radios and were missing turns and information. It was a complete clusterf**k of a trail run. The next morning when we had our driver's meeting and I had asked which channel on the CB were we to be on (as it is up to the trail leader to pick) the CB channel was given and immediately several guys started going off about what frequency they would be on with their HAM or GMRS radio. People were getting confused as to what channel and I could see it becoming another ****-show like the night before. I spouted off and asked if we were a Jeep club or a radio club? I don't think I made a good impression but I quickly pointed out that the bylaws state CB and if you want to change it then go through the proper avenues to get it changed in the bylaws but we should stick to CB's for now so all could enjoy and hear the directions and conversation. Many agreed but I think I may have pissed a few of the senior club members off by my comment.
Sorry for the lengthy response, I'm sure you just wanted to know which navigation app I use rather than my long diatribe response as to why.
Thanks for the question and hope it was helpful.
