strong magnet, bright indicators,

Tough little bugger!

This is a tough little receiver and quite deceptive in it's size. Well built and with really tough magnets, this receiver is every bit as good as you would expect from Topcon. My only issue with it is that the pick-up window (the red part) is limited in size, so it's only suitable for smaller excavators or for finishing work with bigger machines, but this was explained to me by the sales person at Trig when I bought it, so it was my choice to go with the smaller receiver. All in all, it's good value and works great.
