Scubapro Nova 850 Tec Dive Light

Scubapro Nova 850 Tec – Aluminum Primary Dive Light with a Tight, Deep-Reaching Beam

The Scubapro Nova 850 Tec is a handheld primary dive light built for divers who need dependable, focused illumination on technical and recreational dives alike.

If you are pushing into wrecks, dropping into deep reefs, or doing any night diving where you need a light you can trust at serious depth, this is the kind of tool worth understanding properly.

Output and Beam

The Nova 850 Tec puts out 850 lumens through an LED lamp. That is a solid primary-light output, enough to light a corridor, read a gauge in murky water, or pull detail out of a dark crevice.

The beam angle sits at the narrow end of the spectrum. A tight beam like this is a deliberate trade-off: you get reach and penetration into confined spaces, not a wide flood of ambient light. It is well suited to wreck penetration, peering into holes, and signaling a buddy at distance. If you want to softly illuminate a wide area for photography or general reef swimming, a wider-angle light would serve you better.

Depth Rating

The Nova 850 Tec is rated to 1,000 feet (305 meters). That far exceeds the limits of recreational diving and covers the deepest technical dives. You are not going to find a depth at which this light becomes the limiting factor.

Watertight integrity comes from double O-ring seals, a well-established design approach for reliable pressure resistance.

Build and Size

The body is machined aluminum with a matte black finish. Aluminum gives you a good strength-to-weight ratio: the light weighs 10 oz (283g) without the battery and 13 oz (368g) with it. At 1.8 inches in diameter and 9.6 inches long (4.6 x 24.4 cm), it is compact enough to travel with and easy to grip with a gloved hand.

One detail worth knowing: the light head has an extended shroud around it. This is designed to prevent the beam from sweeping across your buddy's face accidentally during a dive, which matters more than it sounds in close-quarters wreck diving.

Operation

The Nova 850 Tec switches on and off with a twist mechanism. Twist-on/twist-off controls are simple to operate with thick gloves and have fewer failure points than push-button switches. There is no strobe mode on this light.

A bolt snap is included for clipping the light to a D-ring on your BCD or harness when you need both hands free. That is a standard expectation for a technical-oriented light, and it is good to see it included rather than treated as an accessory.

Battery

The Nova 850 Tec runs on a single C-type lithium-ion battery, which is not included. C-type cells are widely available, which matters when you are traveling to remote dive destinations. The light also has an over-pressure valve to allow any gas produced by the battery to vent safely. This is a genuine safety feature, not a cosmetic one, and it reflects considered engineering for a light that may sit under significant pressure.

One note: the specs list this light as rechargeable under light features, but the battery is listed as required and not included. Confirm the battery configuration with the retailer before purchase if rechargeability is important to your workflow.

Who This Light Is For

The Nova 850 Tec is a strong match if you are a recreational or technical diver who wants a compact, robust primary light for night dives, wreck penetration, or deep dives where a wide-beam backup light is not enough.

It is not the right choice if you want a wide flood beam for ambient reef lighting or underwater photography, or if you prefer a push-button interface over a twist switch.

For divers who want a light that travels well, goes deep without question, and handles tight spaces with a focused beam, the Scubapro Nova 850 Tec is a straightforward, well-built option.
