Fisher F Pulse Vs Whites TRX Air Tests

I just bought a new Fisher F Pulse pin pointer. How does it compare to my trusted Whites TRX. In the mix we will also pit the Deteknix, simply because I own it. It has never been good for me and always from day one only achieved a couple of inches on targets. Not to spoil the video, but the F Pulse performed admirably. In the next test I will take all 3 outside and test coins in the ground. Thanks for watching.
