Same experience for me as well. I have it on my boat. You get a notice anytime it moves and the wife and family can keep track of me when I am out for multiple days on long tripsI have the Spot Trace and have been very happy with it. The yearly fee isn’t bad at all.
there is an accessory cord and I purchased it as well and is wired directly to my house battery so the AAA’s are never drained.
the app and website are easy to use and work well. My wife logs on and can watch our trip progress as well so if we are late running in she doesn’t worry as she can see us heading for the barn.
