Logitech this week introduced its new entry-level gaming mouse that uses its proprietary Lightspeed wireless interconnection technology as well as its latest HERO sensor. The Logitech G305 mouse uses a proven ambidextrous form-factor but does not offer features like adjustable weight or RGB lighting.

The G305 is Logitech’s second mouse to feature the company’s latest HERO (high efficiency rated optical) sensor with 12,000 DPI sensitivity, up to 400 inches per second detection speed, and up to 40G acceleration. In addition, the mouse uses the proprietary Lightspeed wireless interconnection technology that allegedly cuts the input lag by improving the internal architecture, reducing the polling rate of wireless receivers to 1 ms, rising signal strength, applying a proprietary frequency hopping mechanism that uses the strongest interference-free channel, and optimizing software.

One of the advantages of Logitech’s HERO sensor (and to a degree Lightspeed technology) is a very long battery life. The manufacturer promises that the G305 mouse can last for 250 hours on one AA battery and up to nine months when its polling rate is reduced to 8 ms.

The Logitech G305 is outfitted with six programmable buttons, in line with other entry-level gaming mice. As for weight, it weighs only 99 grams, which some gamers might find too light, but which becomes an advantage when the mouse is used when travelling.

Logitech’s G305 Lightspeed wireless gaming mouse will be available in black and white later this month for a suggested retail price of $59.99. This price is a little bit lower when compared to Logitech’s G603 mouse featuring the HERO sensor as well as the Lightspeed technology ($69.99), but which is more expensive than the price of Logitech’s G502 (starts at $49.99) that has a previous-gen 12,000 DPI sensor, adjustable weight, 11 programmable buttons, and RGB lighting.

    It's a spec regarding the failure speed of the sensor.

    Generally speaking the current generation of top end sensors have reached the "good enough" stage in which it generally isn't a factor anymore but this wasn't always the case. Failure speed for example was an issue with some previous generation sensors (when they were still sub 3 meters per second) as some people during quick flicks could exceed them causing the mouse to stop tracking or other anomalies.

    That number is excessive, but not meaningless. 400 inches per second refers to the max tracking speed of the sensor. Practically, it means "you can move the mouse 400 inches per second and it will still track accurately". Above a sensor's max tracking speed, the mouse won't track accurately any more and you'll experience some abnormal behavior.

    5 years ago this figure was much more important. Optical sensors (which are almost always more accurate than laser sensors) used to have very low max tracking speeds. I believe the revered MLT04 used in the Wheel Mouse Optical and Intellimouse Optical had a max tracking speed of about 1.5 meters per second (5 feet per second, 60 inches per second), and even the modern (at the time) sensors were around this same number. While this sounds plenty fast, in some games (namely Counter-Strike) it's not unheard of for a player to move 15+ inches in a quarter second, which exceeds the max tracking speed of these sensors. In fact, this was such an issue that at one point Logitech included an accelerometer in one of their mice (the G402) to take over for the sensor at a certain speed.

    Nowadays, sensors have progressed enough that max tracking speed isn't an issue anymore (at least for high-end mice), but it's still not a meaningless term, especially for budget mice like this. It's like n-key rollover for keyboards. Being able to press more keys is objectively better up to a certain point (probably 10 key rollover), but once you pass that limit it's not an issue. However, it's nice to know that in some rare instance where you do need to press all the keys, or move your mouse very fast, it won't be an issue.

    Anybody can recommend good NON wireless mouse? My Logitech G500 is just about to die, looking for decent replacement at around $100 or less. Primarily for Pubg and SC2. Reply

    Logitech's successor to the G500(s) is the G502, which is fine. It's a few years old, but the shape and weight should be similar. If you wanted something lighter, there's the G403. I'd go to a local brick and mortar computer store and look at what they have on display. There's nothing wrong with either of those mice. Reply
