• The Hunter adjustment wrench consists of a 3/32 allen key, two convenient finger loops for gripping and an opposite side arc adjustment key for your Hunter PGP, PGJ, I20, I25 and I40 heads.
  • The Hunter Rotor adjustment tool is used to make arc and radius adjustments on each sprinkler in Hunter's product line
  • Tool is not compatible with Hunter Pro Spray and Pop up Hunter Heads. (Smaller heads typically found in shrub zones and boulevards) The correct tool suitable for those heads is the MP Rotator Tool

Works just like the one that came with the sprayer. I don't knw what I did with the old one. I tried using an Allen wrench but couldn't hook up. I almost tore up the sprinkler with a screw driver.

For starters, the total cost of this item was less than the seller's shipping charges. I don't know how THAT works, but I'm certainly not complaining! The company who installed ym irrigation system apparently didn't feel I'd ever need this special Hunter 'key', so I was really happy to get this one from Amazon. Anyhow, the key arrived today & I adjusted the spray radius on one of the heads that had been throwing water onto my front porch. A couple of clock-wise couple turns later, and voila, problem solved. Should you need info on adjusting Hunter spray heads, there's a youtube vid w/a Hunter technician available online. It's ~ 2" in duration & covers the 'key' bases.

This tool is simple, works fine, and does what it's suppose to do. I used it to adjust a Hunter PGP sprinkler that my landscapers used to replace an old Toro one that they destroyed while mowing, but they didn't adjust it completely and didn't leave me with any adjustment tool. As a side note, the Toro ones didn't require any special tool to adjust (which seems better to me but maybe there is a good reason Hunter PGP's require a tool?).

Works really well for our irrigation system. Our old tool broke and this was the tool we needed. We couldn't find it at Lowes or Home Depot. It arrived very quickly.

This little tool is priceless! I didn't know how to adjust the sprinklers but with this inexpensive yet versatile tool, I have all my sprinklers dialed in and working at maximum performance.

Very handy tool to adjust the sprinkler head. I used the company videos on YouTube to provide exact instruction. Wish I'd discovered the tool and videos at the beginning of the summer - I could have used less water with a sprinkler head adjustment (accomplished with tool + YouTube video's).

You’ll need this tool to adjust the Hunter I-20 sprinkler head. It arrived in 2 days and worked perfectly.

We recently had a sprinkler system installed, using Hunter sprinkler heads. The installer did a pretty good job of adjusting the heads, etc., but for fine tuning it takes too long for him to get out to our 25 mile from town home. These let me make those fine tuning adjustments as I see the need. By the way, it is the same tool that the pros use.

Works like a charm - don't try anything else to adjust your Orbit brand sprinklers you may damage them! The bottom end is just a hx key and you could use any similar sized hex tool to adjust the spray, but the rotation adjustment has a differently shaped tool and its made out of plastic - if you go jamming a Philips head into your sprinkler you could damage that portion if you are not careful.
