You’ll have to look very hard at this to prove it’s not a genuine Emlid Survey Adapter, but the price is quite a bit better, if you want to get several of them.
Have you lost one of these before? Don’t buy one, buy two…. or Three. Heck for this price, you’ll never have to get stuck again with a missing adapter.
The price is for just one adapter, the many pictures of multiples are meant to inspire you to get many. (Yes, have many. A Mexican company was selling these, and I had to get enough to get the best price, and make up for customs.)
