The ability to use the gauge without connecting your cell phone would be great and is just plain stupid that it hasn't been like that from the start.
But even worse is the lack of buddy tracking. That feature would be a big safety measure and make the gauge truly worthwhile.
Doo is often the leader in tech but when it comes to their gauges, they are a distant third with what Cat will be offering.
I had to get the big gauge in order to get a sled on time, and would not doo it again unless/until Doo provides some actual value to match the big price.
