I shouldn't have to fix engineering problems on a brand new machine that's been in production for three years.
PINPOINT PRO ERRORS FULL
Next mission, correct the pinpoint fixed full volume firmware bug/feature. Its a huge improvement and worth it, IMO. I've put four hours detecting use on machine since adding fix, and only seen pinpoint problem occur once (probably operator error not holding button down firmly).
I decided to try fixing this instead of sending it back as I am sure all units have this problem and factory could not repair an engineering design flaw. Remove the battery and one screw is under that, while other two screws are on case back.īe aware this will void your warranty. Take care you do not pull on flat ribbon cable attaching the two halfs. If you use an electrolytic capacitor make sure its lead polarity is correct.ĭisassembly is easy by removing three screws and slowly removing back panel. Add capacitor underneath pushing capacitor leads up through holes from below, and soldering into place. The black lead is on the ground signal on the fifth pin. The red lead is on the pinpoint signal on second pin. 47uf capacitor indicated by voltmeter leads. This eliminates microsecond make and break contacts being seen by the computer chip causing it to jump out of pinpoint mode.īelow is a pic shows two pins to connect. 47uf capacitor from the pinpoint switch to ground.
I added hardware fix and the problem was cured. One can deal with momentary key bounce in firmware or hardware. The problem is lack of debounce firmware for the pinpoint button. Some have complained its a bad membrane switch, but I have proven that is not the case. It constantly kicks out of pinpoint mode into discriminate mode on almost every target. My Eurotek Pro works great when discriminating, but has a firmware bug in pinpoint mode.
