There are a few out there I have 3 different kinds I have a garret propointer,sunray probe,automax v2. The sunray is great but its got its limits cuz u have to have a certain 1 & it hooks up to ur detector, my opinion yes its a pinpointer but more of a mini 1" detector attached to ur detector,the automax its alright it works u can adjust sensitivity,& switch between audio & vibrate. Down fall its the size of ur detector lol jk, the pinpoint rod does break not built very strong,can findem cheap will get the job done. My go to which I have 2 of is the garret pro pointer built like a tank,not big I believe like 7" or so somewhere around that has a led light, it will also beep & vibrate & intensify the closer u get to ur target, these r well liked for a reason. Minelabe makes a profind 25 which is very close to the same but costs a little more but u can adjust the sensitivity which comes in handy sometimes. Out of the ones I've tried my best ones would be the garret propointer,I consider the sunray as more a tool or add on to the detector that's great for more info to ur detector hope at least something here helps
