We got a new gel cell battery for the FX3 & gave it a try ouy today. It is supposed to last for several days between charges. Don't know about that yet,but it worked all day today. Anyway about 2 minutes into the first setup a coyote came charging the cottontail distress sound on the Foxpro, partner shot him at about 15 yds.I immediately switched to the coyote death cry & in about 30 seconds another appeared on the run for the fallen one & started a circle. Another bang flop & he was done. Both were mature males in fine shape for Central Ca. No more takers the rest of the day Popped a few squirrels on the way out of the ranch. Another great hunt!
