FYI, the TecTecTec model is just a rebranded model which is sold by MANY other companies. Diamond Tour sells the same one under their own Inazone brand for $89.99: https://www.diamondtour.com/inazone-400-laser-range-finder.html
I had that one for about a year and it worked great, until I left it in my cart after a round and nobody turned it in. That's one reason I'll never spend big $$$ on a rangefinder (or sunglasses for that matter), I'll just lose the damn thing ! LOL
