Now that I've had a chance to fully use the call, I can say that I'm very happy with it.
1. The volume is loud enough for what I do. I don't have much experience with other calls, but I think it is OK.
2. The range of the remote is GOOD. I have been setting the call up on an old tripod that I have. With a clear line of sight, I've had no problems out to 150 yards, and haven't tried any farther than that. Not sure I need to.
3. Battery life appears to be GOOD. I did buy a good set of rechargeable batteries and, even in the cold, they do well. I've made 5-6 stands in the 0 degree weather and they are still showing about 1/2 battery. It is a bit of a pain to have to remove the batteries to charge them but, it works.
4. Speaking of the cold, the display screen on the remote does get a little "slow" in the cold weather. Say you change the volume, it may take it a second to change the light up on the screen. Not a big problem unless you are trying to quickly scroll through sound lists. However, this only seems to happen in real cold temps after the remote has been out of my pocket for 10 minutes.
5. I custom picked the sounds when I ordered it. The sound quality is good and overall I have plenty of sounds to choose from, but they may sucker me into buying a couple more.
6. The "fox-bang" feature that automatically starts playing a preset after you shoot works well. I guess I haven't seen the feature be effective, but I know it works as it should and I can see how it could give you a better chance at a second shot.
7. The timer on the remote is very handy for keeping track of time on stand, how long you've let a sound run, etc. It starts as soon as you turn the remote on and just counts up.
I have called in several coyotes with the call and just haven't been able to capitalize for one reason or another.
There are a few coyotes running around my place but the neighbor kids have been out calling and educating them every week. With the cold temps and the wind right tonight I decided to give it a try, knowing I was going to have to try something different. I pretty much used coyote vocalizations and had a coyote skirt by me in the thick stuff twice in the first 30 minutes of the stand. Knowing he was around, I kept at it and at the 40 minute mark decided I would finish with a pup distress. At about the 44 minute mark he came out and sat in the clear, where I put him down. Not sure that I would have been able to pull this off with hand calls. "Knowing" I was making non-threatening coyote vocalizations gave me the confidence to take that calling approach to the stand and it worked.
P.S. The gun in the photo is the .223 that I detailed the build of. Feels good to finally get fir with that one.
