Fisher F-Pulse important finding

Recommended Posts

Hello everyone, i just bought a F-Pulse and want to share some important findings.

Alkaline AA (Panasonic Platinum Power) = Sens-3, works perfect.

Lithium AA (Energizer Lithium Ultimate) = Sens-3, noisy on everything even holding in mid air.

Hope this helps someone because i've been reading about people thinking there pointer is broken.

garikfox here is some good info on Alkaline and Litium batteries. You should call Fisher and ask them if the Litium are to powerful for your pointer. Check the voltage of each. Also put the sen to # 2. Then try touching the ground with the pointer tip and turning it on then. Hope this helps.
