It offers real-time waveform visualization, spark peak voltage measurement, and timing diagnostics, enhanced by advanced charting to detect intermittent faults, making it indispensable for marine, motorcycle, and automotive applications. ## Description The GTC505 Engine Ignition Analyzer is a handheld instrument designed from the ground up for the diagnosis and performance measurement of all types of spark ignition systems, from conventional to the newest Coil on Plug in use. The GTC505 is capable of displaying and measuring the following in real time: secondary ignition waveform, primary coil current ramp time, dwell time, spark burn time and RPM. It also provides two innovative and unique display formats used to compare measurements between cylinders, and to look at data for hundreds of spark events over time in order to detect intermittent problems, misfires and other performance issues which are very difficult to detect using conventional scopes.

No-one else makes anything quite like it (as a handheld, one-box solution). I've got one, and it's a fantastic time-saver. I can do a quick look at four cylinder's worth of ignition waveforms in twenty seconds. To do the same thing with my Snap-On Verus (five grand's worth) takes five minutes to boot, then a couple of minutes to find and plug up the adaptor, then another minute to configure the scope mode. And I gain little or nothing more by doing it with the Snap-On tool than using the GTC product. **Q: Will this work on a single cylinder lawnmower engine to read rpm? If so what setting would you use?** A: The problem is that when the unit is in tach mode it reads the wrong RPM’s because you you can not set it for the number of cylinders that your engine has. It’s permanently set for “8” cylinders with no way to change it to “1”, “2”, “4”, or “6” cylinders so that the tach function will read correctly. You have the option of setting the unit for a 2-cycle or a 4-cycle engine so why can you not set the number of cylinders? **Q: Does this product have a warranty besides the 4yr protection plan?** A: Yes, the GTC505 comes with General Technologies Corp's standard product warranty, which lasts 1 year (from date of purchase). Please visit the GTC warranty page for details https://gtc.ca/warranty.html If you have problems after the warranty period, please contact the manufacturer, as GTC can often provide replacement parts, or repairs. **Q: Can this be used to set ignition timing instead of a timing gun?** A: Nope. There is no strobe to illuminate the timing marks on the vibration damper. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 何処から発送？ *by イ***チ on 22 June 2025* お近くの配達店まで輸送中です、何処？ヒューストン！ お近くの配達店に到着しました、何処？アンカレッジ！ 日本に到着してからは思ったより速く1日で配達されました。 メード・イン・カナダなんですね。 心配になりましたが、ちゃんと新品でした。 カイセより選択項目が多いようです。 ※verupされた？ ### ⭐⭐⭐⭐⭐ Muy buen articulo *by J***Z on 23 May 2025* Exelente producto ### ⭐⭐⭐⭐⭐ Well designed and built, but problematic choice of probe connector *by T***H on 31 January 2020* Pros: This tool is very well designed with a robust case and solid plastic buttons that have a quality feel when pressed. The software is innovative and provides useful modes and views as described in GTC materials. It is great to have a tool that features probes for BOTH spark plug wires and coil on plug (COP) systems. When using "tachometer" mode, the RPMs are fairly stable both in chart and digital view. This is a really big plus. Cons: In chart view, the highly variable secondary spark voltage jumps around and you have to visually ascertain an average value. You can estimate an average kV by comparing real-time kV readings to the y-axis label values. It would be best if in digital view, the average kV was shown in addition to min and max. Not a serious problem though. Spark plug kV will jump around a lot because of real-time changes in resistance at the plug, timing changes, etc. On the tool I received, the BNC female connector for the gooseneck probe on top of the unit fits somewhat loosely and its weight can make it rock back and forth a bit. In my opinion this can eventually loosen the inner conductor sleeve of the female BNC and maybe lead to intermittent connections. BNC connectors can have this problem, for example when matching 75 ohm connectors to 50 ohm connectors. Fortunately conventional coax cables with BNC male connectors are lighter in weight than the gooseneck probe and they do seem to fit more snuggly. You can get a 3 to 6 ft flexible coax cable with male and female BNC connectors and fix the probe to the end of the cable to use as a test wand. Alternatively, GTC makes a 2 meter flexible coax cable that accepts all the probe tips, and gets around the problem of a loose fitting gooseneck probe. It also has a locking spark plug wire probe. The part number is GTC505-CSC and you can order it directly from GTC for a reasonable price. If your gooseneck probe fits loosely to the BNC connector on top, I would definitely get a coax extension cable or the GTC505-CSC. Amazon should stock this accessory. Otherwise it appears to be a very fine tool and worth the cost. ## Frequently Bought Together - GTC GTC505 Engine Ignition Analyzer - Spark Diagnostics and Tachometer Readings for Marine, Motorcycle, and Automotive Mechanics, General Technologies Corp - OTC 5609 Cylinder Leakage Tester Kit , Black - OTC 5613 Vacuum/Pressure Gauge Kit --- ## 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.ae/products/275705962-gtc-gtc505-engine-ignition-analyzer-spark-diagnostics-and-tachometer-readings](https://www.desertcart.ae/products/275705962-gtc-gtc505-engine-ignition-analyzer-spark-diagnostics-and-tachometer-readings) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-24*
