When you’re out on the water, the last thing you need is a complex interface getting in the way of your catch. Thankfully, fish finders have become increasingly sophisticated, providing an array of details about what’s going on beneath the surface. But with all these features and functions, it can be a bit confusing.

This guide will help you understand what MS PM2 means on a fish finder and how to use it effectively.

MS PM2 Explained

Unpacking the Terminology

Before we dive in, let’s clear up some confusion: MS PM2 isn’t a standard term you’ll find on every fish finder. There’s no universal agreement on fish finder lingo, as terminology can vary greatly among different brands and models.

The Usual Suspects: MS and PM

Although MS PM2 might not be a standard term, the acronyms “MS” and “PM” are frequently found on fish finders. “MS” typically stands for “manual sensitivity,” allowing you to manually adjust the sensitivity of the fish finder to pick up more or less detail. “PM,” on the other hand, usually represents “power mode,” controlling the fish finder’s power output to the transducer.

Deciphering the Numbers: PM2

The Power of Two

The “2” following PM in PM2 likely refers to a second level or mode of power output. It could be that your fish finder has multiple power modes for different fishing environments or conditions.

Applying the Knowledge: Using MS PM2

Setting Sensitivity

If MS stands for “manual sensitivity” in your fish finder, it means you can adjust the level of detail your device picks up. A higher sensitivity setting will show more detail, including smaller fish and debris. A lower sensitivity setting will show less detail but might be useful in murky or cluttered waters where too much information could be confusing.

Power Modes

If PM2 refers to a second power mode, you may need to consult your fish finder’s manual or manufacturer for specifics on its usage. Generally, different power modes are used for different fishing conditions. Higher power modes might be better for deeper waters or high-speed trolling, while lower power modes could be used in shallow waters or when you’re stationary.

What is MS PM2 on a fish finder?

While MS PM2 is not a universal term found on all fish finders, “MS” generally refers to “manual sensitivity” and “PM” to “power mode.” The “2” in “PM2” likely indicates a second power mode setting. Always refer to your device’s manual for accurate information.

What is manual sensitivity on a fish finder?

Manual sensitivity on a fish finder allows you to adjust the sensitivity level of the device to show more or less detail. Higher sensitivity will display smaller fish and debris, while lower sensitivity will show fewer details, useful in cluttered waters.

What is power mode on a fish finder?

Power mode on a fish finder controls the device’s power output to the transducer. Different power modes can be used for different fishing environments or conditions, such as deep or shallow waters.

Can I adjust the sensitivity on my fish finder?

Yes, most fish finders have a function (often labeled as MS or manual sensitivity) that allows you to adjust the device’s sensitivity level.

What does the number following PM mean on a fish finder?

The number following “PM” on a fish finder usually indicates different power modes. For example, PM2 would refer to a second power mode.


Understanding your fish finder’s features, such as MS PM2, can significantly improve your fishing experience. While it might seem like you’re drowning in a sea of acronyms and numbers, a little knowledge goes a long way in mastering these modern fishing tools. So, get to grips with your gear, and you’ll be reeling in those big catches in no time.
