Question: can you purchase additional calls for the unit or do you have to buy another seperate unit?
Document: I received my GC101 three days after ordering it. Packaging was very good & well protected, I bought it for hunting, so far I have only tried it at the house, it works great, I will write another review when I have actually used it for hunting coyotes or whatever. As it is, I have high hopes for its use in the field. My only problem is, can you buy other calls for the unit, or do you have to purchase another remote unit? I can't find anything on that subject.
I put the 4 AA batteries inside the speaker, hit one of the buttons on the remote and nothing happened. I do not know if the signal between the remote and speaker just did not work, or if it has a loose wire. Either way, I am not dealing with this. This is the first electronic call I have purchased and I will never purchase another.
I've heard electronic calls that are louder, and I've used some with longer remote range...but for the price I paid I think this call represents a fine value. The calls sound good and should be loud enough for most hunting setups. The remote worked consistently at 50 yards but became a bit spotty beyond that range...I was still able to control the unit via remote beyond 50 yards, but I had to be much more deliberate when pressing buttons, hold the buttons a bit longer or press multiple times, etc.
Joke. Buy a real one, spend the money. The remote doesn't work past 30 yards. Just one mans opinion. Happy hunting.....
It is a great buy for the price. It works well for a beginner which I am. I will say every time I have used it, I have had to hang it up for the remote to work. But, you get what you pay for and for the price you can't beat it.
Not a lot of calls. But for the money can't complain. I'm just starting in coyote hunting so you basically you get what you pay for.
I didn't use it at 100 yards but would be surprised if it worked reliably at that distance. Having said that, I'm still happy with the purchase, especially for the price, and would recommend it to anyone looking for a simple handful of distress sounds, particularly if you are setting up and brushy or wooded areas where your remote-distance requirements will not be too long.
Its a good caller for the beginer. Battery life seems to be very good. It could use a couple more types of calls. I my area i don't have bobcats So that call is kind of worthless to me.
I bought this for my Dad who is an aid hunter and has been for years. With that being said, he is extremely particular about his calls. I was hesitant at first but went for it and am glad I did. He really likes the call and has per him (I have no idea) sounds like a real call.
I was worried that this thing was too small to call anything in but I needed a portable unit because I hike long distances. On my first time out with it I called in a grey fox mid day with the cottontail distress. Needless to say I was impressed.
