Hand-held Pinpointers Vs. Power Source: I have owned and used a lot of Pinpointers, looking for one that was 'Simple' to use, had a 'Functional' settings control w/o a lot of tinkering around, and provided me reasonable 'Performance.' I do not use a pinpointer all the time because I can usually isolate a target well enough with the detector, and a lot of the sites I hunt, targets are easily acquired in a medium like bark-chips or sand in tot-lots, or simply 'toe-scuffing' a lot of the softer soil in ghost towns or similar out-of-the-way places. I see people who draw their pinpointer on just about every target they detect .... I don't. I used them, don't get me wrong, but I don't over-rely on them.
Some Pinpointers I didn't like do to lack of performance or reasonable depth, some I didn't like because of their lack of build quality, and some I just didn't like, period. Through the end of 2014 there were two Pinpointers I liked and kept around. The White's Bullseye II and Garrett Pro-Pointer. I liked the feel of the Pro-Pointer better, but for whatever reason, they just didn't seem to last and sometimes didn't make it through one year's typical detecting season. Both of those pinpointers would go through perhaps 2-9V batteries a year. Always a quality alkaline battery was used, and like I said, I don't grab them on every recovery, so I don't know if any of them had a circuitry design where there was a little battery drain even when Off and not-in-use. The Pro-Pointer seemed to need battery replacement a little more often, but there was not a major warning they were getting weaker in either device, you could just sense it when using them and the detection depth and signal strength started to weaker. Just time for a battery change.
Early January of 2015 I got a Makro Pointer and really liked the feel and performance and simplicity of adjustment. It immediately went on my gear belt, and has stayed there now for just over 5 years. Works well and is very reliable. 5 years, and it's still running fine on its 2nd 9-V battery. I didn't put my VOM on it to test, but used a simple Battery Checker recently to check batteries in all my devices and that 9-V still registers well up into the 'Good' range. Two 9-V batteries and I'm starting my 6th year with the same Pinpointer. It made me wonder, at the time, why so many pinpointers I have had in the past go through a battery more often, and some much more often? One P-P used 3 in a year. Oh, I was out detecting more often than I can now, but why 3 in a year when my current Pinpointer is going into its 6th year on the 2nd 9-Volt. ????
Anyway, today I use three (3) different Pinpointers. My very trusted Makro Pointer just starting year #6, and starting it 1st year is my Nokta / Makro Pulse-Dive Pinpointer. I easily check the three boxes I apply to any evaluated product, and that is to be 'Simple' yet 'Functional' and provide 'Performance.' Plus I like the feel of the device, and this one relies on a built-in Li-Po battery to charge. My 3rd pinpointer in the wireless XP MI6 that pairs with my XP ORX detector, and the MI6 is also a rechargeable battery powered pinpointer. So, only one I use requires a 9-V battery, and after 5 years of reliable performance and long-lasting battery power, I still wonder why some folks have to change a battery more often.
I did have one pinpointer that I gave away last year. Had it for almost two years and kept it ready as a 'quick-grab' if I just hopped out to check a site or hit a tot-lot or something. It was solid and reliable and worked well. but it also worked when I didn't want it to. Sometimes I'd hear a weak beeping nose, and with my bad hearing and the pinpointer on the back seat or in the back of my GMC Envoy it wasn't loud and sometimes I didn't hear it but someone riding with me would. I'd get out to check and it was the Pinpointer that had mysteriously turned On. I'd turn it Off, check it by my car body and verify it was 'Off, but maybe in a while or the next day or, whenever, I would hear a noise and, sure enough, it had turned back On. That was a Nokta RS Pointer I got on a detector purchase deal. It looked fine but I don't know if it had every been dropped or what the cause was. It wasn't loose and rattling around, just laying on the seat or in a holder in the back of the vehicle.
All the Garrett Pro-Pointers I had that didn't last long were the original black versions so maybe they had some sort of glitch and batteries discharged a little even when 'Off'? Sometimes they'd get erratic and a battery change corrected that, and other times a fresh battery didn't seem to fix a thing and I just junked them ... keeping the fresh battery of course.
