Replacement Probe for Tri Electronics GXL-24-L Electronic Gold Testers

I HAD REPLACED THIS PROBE 4 TIMES , I WON'T RECOMEND AT ALL THIS PRODUCT TO ANYONE, THE TOP PART THAT TWIST AND PUSH THE GEL BREAKS DOWN SO EASIER, SO THAT WAY YOU ARE FORCED TO BUY ANOTHER ONE FOR $50 DOLLARS, THAT'S A BIG RIP OFF.....DON'T BUY IT....PERIOD
