Mares HORIZON SCR NON DECO XR Line

4,499.00

The Mares Horizon is designed with one clear purpose: simplicity! It is easy to setup, transport, dive, and maintain, since every component of the unit is accessible by the user. The unit’s internal components are easily accessed by removing the scrubbers that are located under the main outer cover. To keep everything small and light, the gas supply for the unit comes from one or two off-board cylinders, which gives the diver an experience similar to sidemount diving.

Description

The Mares Horizon is designed with one clear purpose: simplicity! It is easy to setup, transport, dive, and maintain, since every component of the unit is accessible by the user. The unit’s internal components are easily accessed by removing the scrubbers that are located under the main outer cover. To keep everything small and light, the gas supply for the unit comes from one or two off-board cylinders, which gives the diver an experience similar to sidemount diving.

The Mares Horizon is designed to allow for diving within the no-decompression limits or for decompression dives up to a maximum depth of 40 meters. To accelerate decompression two different gas mixes can be used; bottom gas and decompression gas. The bottom gas is used during the descent and bottom phase of the dive and the decompression gas is used for the decompression phase of the dive. Both bottom and decompression gases must meet the following criteria:
Minimum Oxygen Content: 30%
Maximum Oxygen Content: 100%

The Dive Controller (DC):
The Mares Horizon Dive Controller (DC) is a high end, reliable dive computer that also plays an important role in configuring and executing dives with a variable flow SCR. It allows the user to enter breathing gas data as well as defining oxygen fraction setpoints to maintain during the dive.

Alarms and warnings:
A warning is issued if any dive parameter is outside of its expected operating range. These warnings are displayed in situations where the diver’s life is not in danger

Info:
Extended dive time
The Horizon offers incredibly extended dive time compared to open circuit dives, giving the diver ample time to take in the wonderful underwater environment.
Dive times are an average of 3-8 times longer
Standard nitrox gas cylinders available at the dive destination can be used
One or two Nitrox gases diving possible

Lightweight
The lightweight system is the ideal travel companion and does not require dedicated cylinders or weights.
The unit’s simple logistics allow the diver to use standard nitrox cylinders that are easily obtained from most dive destinations.
Complete unit weighs only 12kg for easy transportation
Comes with 1 bottom gas regulator set weighing 1.4kg
Optional decompression gas regulator weighing 1.4kg is also available
Combined, the Horizon unit and regulators should fit in a single suitcase, weighing less than 23kg in total – the standard checked baggage allowance for most airlines

As easy as nitrox diving
The Horizon SCR training builds on a foundation of open-circuit and nitrox diving knowledge, and the Horizon SCR controller intuitively maintains programmed nitrox mix, depending on diver preferences. Fewer bubbles allow wildlife enthusiasts to experience close encounters like never before.
The gas mix can be changed during the dive (using the controller) to extend dive time or decrease decompression time
The controller will warn the diver if an inappropriate gas mix exists

Creates a natural diving position
The Horizon SCR provides warm and moist breathing gas, and an ergonomic design that intuitively improves the diver’s trim position and comfort.
The shape of the Horizon unit provides the ideal, horizontal trim
The combination of warm gas and improved dive position makes breathing natural and effortless
The specially contoured, ergonomic unit includes a soft back plate, lumbar support, buttplate and padded harness straps

Fail-safe gas operation
The Horizon SCR was designed to maximize safety and ensure exceptional performance using multiple back-up safety systems and three sets of redudant electronics and power supplies. A smart, diver-adjustable HUD visual indicator informs the diver of their gas supply status using a pulsing LED light, and in the unlikely event of an electronic shutdown, the diver can switch to the BOV, ensuring a continuous and safe supply of breathing gas.
During a total system failure, the unit supplies an open circuit nitrox breathing gas mix
A sophisticated monitoring system informs the diver of how much time remains before they must replace the scrubber material
Regulator set(s) provide alternate gas sources that can be shared in an emergency situation

Ready for advanced divers
For the more advanced diver, the Horizon offers a range of advantages. As well as a longer dive duration, the diver has dual gas possibilities – with the option of attaching a second cylinder with a higher O2 concentration for accelerated decompression.
Uses the ZH-L16C Bühlmann algorithm with gradient factors
Programmable bottom gas and decompression gas
Within operational limits (up to 40m) the unit provides decompression obligations like that of a closed-circuit rebreather
