Over the years I have tried everything to get deer in front of my cams from Trophy Rock to home made mineral licks to Deer Cane and Buck Jam and the best thing I have found is generic 50lb. mineral blocks that you can get at your local feed store for $6.00 each. I have gotten pics of hundreds of bucks using these blocks over the last 2 years.
I dont know what ingredients, salt or trace minerals etc. are in them but then again I dont really care since mineral blocks, licks etc. do nothing to benefit the herd but the deer sure do like them!! Pike
