“Is this Delta Upland device a 2014 model? Can you get a 550 Pro model? its the same price as this one,but in addition to featires similar to the upland,has a strobe on the collar so you can see where your dog is when walking it at night.If you don't carry it,can you special order it from Garmin/Tri-tronics?The other model for 2014,has the strobe on it as well Its the same price and a better value.You should stock these models too if you can get them”
