I got the fisher equivalent. I thought it might unseat my TRX as prime pointer. It didn't. The vibration was much weaker (I don't use sound.) and covered a larger area than the TRX. It didn't seem to get stronger as I came closer to the midpoint of the target. When I ratcheted it, it was hard to locate where it would vibrate again. On deeper targets, it wouldn't vibrate at all where the TRX gave a good signal. I had both at maximum sensitivity. I thought it being deep on the sides would be a help locating the target but for me it was much easier to locate with the TRX. After dark the Fisher lights up the area where the TRX is lacking so then I will be using it. Don't get me wrong, it is a very good pinpointer with some advantages but for me the TRX still rules. YMMV
