Review: High quality tool, highest recommendation. - A rugged well made tool that works very well. Same hi vis yellow plastic and black rubber grips as Dewalt Tools. I really like the adjustability of it. At full sensitivity, I get it within a few feet of a circuit or fluorescent light and it starts buzzing. All the way down and it does not detect anything, so the range of adjustment is fantastic. I can dial it in so precisely that I can hold it on one side of an insulated wire and it will not go off, but when I move it to the other side of the wire (where the hot conductor is) it goes off. That's accuracy to a few millimeters. Best way to use it is to calibrate it ahead of time. Stick it in the hot side of an outlet, on a wire or conduit, hover it over a wall switch or outlet that you know is hot and adjust the knob until it buzzes, now it's ready to test the unknown circuit. I live in a 60+ year old house with plaster and chicken wire lathe wall construction. At a little more than 1/2 sensitivity it detects the wires inside the wall, inside of metal conduit. By moving it back and forth and seeing where the buzzing starts and stops, I can trace exactly where that wire is in the wall between the studs. Makes it easy to trace or detect wiring in the walls before I cut or drill through. If you will only use one of these to stick into outlets or against wires to see if they are hot then the adjustability feature may be overkill, but to get a lot of varied use, I'l glad I chose this one. Review: Can be indispensible at times - Excellent tool. Response is very good; just takes a little getting used to for approximating position of indicator on dial for a given job, along with a judicious bit of 'touch and go' tweaking. For example, sensitivity can be adjusted to facilitate reliable detection of an individual hot wire in a box with several wires in close proximity of each other – and will enable detection of hot and neutral slots of receptacles to verify correct/incorrect wiring. At max sensitivity setting, a signal can be detected at an approximate distance of 12" to 18" thereby permitting a rough idea of hot wiring behind drywall. The only potential drawback would be attempting to use while wearing gloves, the 'feel' of the dial will be very difficult. The switch near the front must be depressed while in use which may be a bit annoying to some, however, one can guarantee that one will definitely not forget to turn it off (is the glass half full or half empty? It all depends upon your point of view). ## Features - DURABLE: Hi-Impact Resistant ABS housing with soft over-molded rubber grips with a compact ergonomic design - CIRCUIT SENSING: Adjustable Non-Contact sensitivity detects 12-1000V AC and patented battery self-test feature - AUDIBLE AND VISIBLE INDICATOR: 360° visual and beeping audio Non-Contact Voltage Detection - PERFECT SIZE: Easily fits into any pocket or tool belt - includes a pocket clip - RATED: CAT Rating III 1000V, IV 600V, 10 ft Drop and 250 lb Crush ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000GLAC5G | | Best Sellers Rank | #16,527 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #201 in Multi Testers | | Brand | Sperry Instruments | | Brand Name | Sperry Instruments | | Color | Red | | Customer Reviews | 4.3 out of 5 stars 986 Reviews | | Global Trade Identification Number | 00035632064793, 50035632064798 | | Item Dimensions | 2 x 3 x 4.75 inches | | Item Type Name | Adjustable Non-Contact Voltage Sensor | | Item Weight | 0.01 Ounces | | Item dimensions L x W x H | 2 x 3 x 4.75 inches | | Manufacturer | Sperry Instruments, INC. | | Measurement Type | Voltmeter | | Minimum Operating Voltage | 12 Volts (AC) | | Model | VD6505 | | Part Number | VD6505 | | Power Source | Battery Powered | | Specification Met | Cat Iii 1000v/Iv 600v | | Style | Adjustable Non-Contact Volt Tester | | Style Name | Adjustable Non-Contact Volt Tester | | UPC | 666116005669 077344278402 705554427654 035632064793 003563064793 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Sperry Instruments - **Color:** Red - **Item Weight:** 0.01 Ounces - **Power Source:** Battery Powered - **Style:** Adjustable Non-Contact Volt Tester ## Images ![Instruments VD6505 Adjustable Non-Contact Voltage Sensor, 12-1000 V AC - Image 1](https://m.media-amazon.com/images/I/61S8RNP6f1L.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ High quality tool, highest recommendation. *by A***E on May 20, 2015* A rugged well made tool that works very well.

Last week I finally decided to buy another, to replace the one that I. . .ugh. . . found yesterday. With several sensors (i.e. those with a twisty power switch / battery cover on the butt) I've often had the cap pop off, or the power not be on / off as it should have been. No such troubles with this sensor. Battery life is great. My first sensor is on its first battery. (I don't use it daily, but I do use it frequently - in the 3 or 5 years that I've had it, I've used it on at least hundred jobs.) The adjustable sensitivity is great, though it comes with some extra responsibility. Turned way up, one can find low voltage, wires in walls / conduit, even "live" neutrals. Turned down, one can discern which wires are live, even in a crowded box. Here's the catch: one needs some "known quantity" to set the sensitivity. I'll give an example of what I mean. Set too high, the sensor may read an outlet as live just because the neutral is connected. Too low, it will give a false negative. So to check an outlet, one must put the probe up to a live outlet, and turn up the sensitivity until it *just* reads. And here comes the one con I'd note for this sensor. The dial is not graduated, and its range is outstripped by the range of sensitivity. I.e. the difference between "too much" and "not enough" is small, and once "just right" is lost (i.e. the dial is moved) one cannot reliably return to it without re-checking the setting. Bottom line, this sensor is very reliable and flexible, if one is willing to fuss with the sensitivity. I definitely recommend this over any "twisty butt" models, which I've found to be unreliable, (from several manufacturers). --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/2320467-instruments-vd6505-adjustable-non-contact-voltage-sensor-12-1000-v](https://www.desertcart.co.uk/products/2320467-instruments-vd6505-adjustable-non-contact-voltage-sensor-12-1000-v) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-30*
