Solo 421-S Portable Spreader settings may vary depending on how fast you walk. If you need to use 3.6lbs of product per 1,000 sq ft you would add 3.6 lb of product to spreader, start with a medium setting, then apply product to a 20 x 50 ft area (1,000 sq ft). If you have product left, your setting is too low. If you run out of product, your setting is too high.
The Solo 421-S Portable Spreader can be used with Amdro or Extinguish, however, this spreader will hold up to 20 lbs of bait. It is mainly used for larger jobs but can be set to cover a smaller radius if needed. You would need to look at the user manual of the product in the picture D.

You would use this along with the reflector shield to guide the granules you are using to the smaller radius that you would like.

While the Solo 421-S Portable Spreader can hold up to 20 lbs, you could use it to apply baits such as fire ant bait. We recommend using the lowest setting on the spreader and still applying very sparingly. Per the spreader manual, pelletized fertilizer (maybe a little large than that granule bait) is usually thrown about 10-12 feet in front of the operator and about 5-7 feet on each side at 55-60 rpm. We always recommend calibrating your spreader over a small area of 1000 sq ft before treating the entire lawn so that you can adjust as needed.
The Solo 421-S Portable Spreader has fully enclosed gear box with lubricated metal gears assure long life and durability. Padded strap with comfortable, cross-shoulder design. 6 in. opening with screw-on cap. Hopper stands upright whether empty or full.
Unfortunately, we do not have the spreader settings for Solo 421-S Portable Spreader and Best Turf Supreme 16-6-8, and since the manufacturer does not list that spreader on their bag we are unsure what the exact setting would be. Due to the thousands of granules on the market and just as many different types of spreaders, there isn't a master list that exists. You may want to try calling the manufacturer of your spreader or the chemical itself directly, to see if anyone on their staff has that info. Otherwise, you will want to calibrate your spreader to the product you are using and its application rates. You can see a short video on how to accomplish this below.
