I have carried two PP'ers for years, one is the TRX, but if I could only carry just one pointer, the TRX would not get the nod. That tip only detection just keeps me down on the ground too long, having to move the tiny flashlight-tip-detection beam, after dirt is out of the hole. The TRX is great for the extra inch it gives which the Carrot misses, so the TRX is cool in pre-dig when the depth meter on the detector indicates 2-3 bars.
As far as pinpointers going off a lot and needing lower sensitivity? Simply tap the power button on the Carrot during the episode, and it retunes. Easy-peasy. I run every pointer I own at full detection setting. jmq2c
