I've got an SME the newest model. If you can put both the sending unit and receiving unit on a tripod it will work great. I wound up doing a Kindle fire for the viewing screen instead of my phone. Phone is too small for old eyes. SME has excellent service if you have trouble. I haven't had any problems doing a mile with it.Shotmarker .looks great but I can't justify the price. Was wondering about the SME unit because it's on sale at Midway although I'd be choking even at $400. Don't shoot anywhere near as much as I used to.
I had the old model it was horrible. In fact they replaced it at no charge with newest model and it's great! Your android will work with it.I would need to use a Galaxy Tab A (android). The reviews for the SME app were not too encouraging. They basically said the old version was good but the new was horrible.
