I reviewed the a budget tier SVBony SV28 a few months ago and found it to be good value for a sub $100 spotter. The SV46 is a big step in features and a moderate step up in price.
It’s optics, while underwhelming, are on-par with similar scopes in this price tier and magnification range. The Athlon Talos has better glass but has less features and looks and feels cheaper in comparison. The SV46 has a well built tube, adjustments, and controls normally found on spotters twice its price. As evidenced by very tight seal on the lens cover, is extremely water tight.
