Have heard a lot about Athlon Optics and got the Midas TAC of their riflescopes that by far is the best bang for the buck product. Got the Argos HD spotting scope this time. I would say WOW, WOW, WOW!!! This spotter is amazing...just blow my mind. I can not believe how well it is built. The first impression is the product got packaged very well with a very nice box that looks very high end. After I took the product out of the box, I noticed the weight is there...nothing like those cheap products almost weightless. The spotter is buit really well with a great beefy and elegant European style exterior. The big focus knob in the middle is very easy to use and has a wide range that the product stays on focused, not like my old scope that has very finiky focus knob. The knob has very smooth turn and just right amount tension. The coating looks really good on both objective and ocular side. The power ring is on the ocular piece and very easy to turn without any binding or grinding noise. The magniciation has 20-60 range and I can easily spot shot impact for a 1000 yard target. Compared it with my friend's Vortex Viper HD 20-60x85, he was shocked by the clarity of mine as he paid almost three times more on his. I could not be happier with this purchase. I know I am covered with their life time warranty same as the riflcope I have.
