- + Half the price of the Suunto D4f
- + Simple interface, easy to read underwater
- + Covers depth, time, surface interval, basic session log
- + Lightweight and comfortable to wear
- + Reliable Cressi quality
- − Limited alarm options compared to D4f
- − No Bluetooth or companion app for dive log review
- − 40m depth rating, adequate for most recreational diving
- − Will feel limiting once you're training seriously past 25m
Overview
The Cressi Newton is the right first computer for most freedivers. It tracks depth, time, and surface intervals, the three data points that matter most for safe recreational freediving, in a simple interface that you can read at 15m without thinking. The cheaper Cressi Nepto drops the surface interval, and the Cressi Leonardo adds scuba modes that a pure freediver will not use.
The Value Case
At $150, the Newton is less than half the price of the Suunto D4f. The D4f's premium buys programmable alarms, a companion app, and a 100m depth rating. For divers who don't use those features (and most beginners don't, at least not yet) the Newton delivers the essential function at a fraction of the cost.
What It Does Well
Surface interval tracking. This is the Newton's most safety-relevant contribution beyond depth display: it shows how long you've been at the surface since your last dive. For following the 2:1 rule (rest at least twice the dive time), having this number visible on your wrist is more reliable than using a separate timer or counting in your head.
The display is large and high-contrast. Readable at depth in daylight. The backlight works for low-light conditions. The interface has no complexity to learn.
Where You'll Outgrow It
When you want to set a depth alarm for training targets, the Newton doesn't have it. When you want to pull session data to a phone and look at your depth profile, the Newton doesn't have it. These are real tools for structured training. Once you're diving 2+ times per week with specific depth progression goals, the D4f starts earning its premium.
