TUSA Launches SAV-7 EVO2 DPV

I first came across TUSA scooters being dived 'in anger' (aka used for real) during Divetech's annual Inner Space rebreather event held in Grand Cayman.

Inner Space 2012, Rosemary E Lunn, Roz Lunn, Divetech, scuba diving in Grand Cayman, scooter sign, Nancy Easterbrook, The Underwater Marketing CompanyI was happily bimbling along the wreck of the USS Kittiwake when a rebreather diver whizzed past me. For a brief moment I couldn't work out how he was moving so fast. His hands were full of a quite large camera system and he wasn't appearing to fin at all. And then I spotted that his legs were almost akimbo. He was sitting on a bright yellow TUSA SAV-7 EVO scooter - rather like someone would straddle a horse - and this was efficiently driving him through the water.

TUSA has just launched the the latest iteration of their diver propulsion vehicle - the TUSA SAV-7 EVO2.

This scooter has a useful depth rating of 70 metres / 230 feet and features the patented 'Hands-Free Riding Saddle'. If you are not familiar with this DPV, this is a 'hands free' scooter. You navigate it by twisting and arching your body accordingly, leaving your hands free to take photographs or check your gauges and computer, hence the seat on both the EVO and EVO2 is quite important. Very loosely it could be compared to a Western saddle. A flange or flat raised pommel (incorporating a lifting handle) is located to the front and the rear of the saddle. Attached to the front plate of the saddle, below the flange, are two wing arms. One on each side of the plate. These are secured in place by a 'super knob', basically a large nut. To use the relevant wing, you unscrew the knob and swing the relevant arm out 90 degrees, before screwing home the knob again.

Just imagine the diver is lying horizontally face down with the DPV secured between their legs, as if they were sitting astride a bar stool. The wings are reminiscent of pillion foot pegs on a motorbike. However they are longer and there is no physical contact by the diver piloting the DPV, ie they are not lying on them. The wing is a handle for an additional diver to hold onto for towing purposes, or they are a means of attaching equipment to the DPV. Two holes have been cut into each wing, allowing you to clip or karabina off kit to the wing. When not in use, the wing(s) can be retracted and secured in place to provide better steamlining, as they lie on the front of the saddle plate. TUSA state that this DPV is capable of comfortably towing two divers, hence the two wings.

I can see this scooter being quite popular in resorts like the Maldives where the currents are famous (or infamous?) for their strength. Whilst it is possible to mitigate for hard currents by diving at specific tide times, using reef hooks and diving with the current, there are times where you just want to go and look at a particular coral head, or fully explore a wreck, and you cannot get there because you are unable to swim against the hard current, or you do not have the time or gas to do it. TUSA state that by using a DPV you can travel 3 / 4 faster than finning normally. Plus using a diver propulsion vehicle can decrease fatigue and reduce gas consumption therefore allowing the diver to go further and faster in a variety of conditions, extending their time in underwater.

So what has TUSA changed on this model? Three things: speed, range and runtime.

SAV-7 EVO2 DPV, diver propulsion vehicle, TUSA SAV-7 EVO scooter, XRay Magazine, X-Ray Magazine, Rosemary E Lunn, Roz Lunn, The Underwater Marketing Company, scuba diving magazine, underwater motorbikeThe design of the rotational speed adjustment function has been reviewed to make it quicker and more responsive, and the DPV is now capable of 4.5km / 2.8 mph compared to 4.2km / 2.6mp on the previous model.

TUSA has also substantially increased the range, torque and burn time by exchanging the Lead-acid battery for a high performing, long-lasting Lithium-Ion Battery (complete with an L.E.D Battery Life Indicator). The SAV-7Evo had a range of 4,200 metres / 2.6 miles with a burn time of 80 minutes. The Evo2's figures are quite impressive. A range of 7,200 metres / 4.5 miles with a burn time of 120 minutes. Available in black.

Here are the specifications:

Speed: 4.5 km / 2.8 mph
Depth Rating: 70 metres / 230 feet
Dimensions: Length 720mm x Width / Length 28.5″ x Width 13.5″

The Verdict is in – The 2011 UK Diving Trade Show

250 Trade Personnel (including Dive Centre Owners, Shop Managers, Pro Instructors, manufacturers and distributors), 20 Exhibitors, 6 members of the Diving Media (British Diver, Diver, Dive The World, Scuba, Sport Diver, X-Ray Magazine), 6 Training Agencies (ANDI, BSAC, GUE, IANTD, PADI, SAA), 2 members of the HSE Diving Inspectorate and 1 professional cartoonist attended the 2011 UK Diving Trade Show on Sunday 27th and Monday 28th November 2011.

During the two day event 12 talks were given covering topics such as "Ecopreneurship" (David Jones), "Is your website working for you?" (Richard Howes), "The down and dirty on image copyright" (Simon Brown), "The BSAC snorkel diver course" (Margaret Baldwin) and "Power Up with Proven Business Practices" (Simon Chance).

Dr Neal W Pollock, (the Canadian version of Professor Simon Mitchell), DAN America's Research Director and the event's key note speaker went down a storm with the attendees.

He gave two exceptionally useful, entertaining and educational talks to industry personnel covering "How fit is 'fit to dive' " and "Thermal stress and diving. "I've been inspired to start exercising again after listening to Neal", observed one delegate.  Meanwhile a number of the audience in the Thermal Stress talk soon discovered that they were probably not bordering on hypothermia following a winter dive at Stoney Cove. While less exciting on the fish story scale, they were merely "just cold".

Cold water featured heavily during the UK Diving Industry Christmas Party when award winning cinematographer, Doug Allan, gave a mouth-watering presentation on the BBC's Frozen Planet series.  The talk kicked off with a brilliant sequence filmed from a helicopter.  The shot began with a wide view across the polar ice that continually tracked to eventually swoop in low, and closed with a very tight image of a Polar Bear. Over the next 30 minutes Doug transported the entire audience to polar regions with his superb imagery and stories.

Another man with an interesting story was Fraser Bathgate.  This year he was the first Brit to win the DEMA Reaching Out Award, and this was acknowledged during the Dinner - Fraser received a much deserved standing ovation for the work he has done in the field of disabled diving.  It was fitting therefore that the raffle was in aid of Deptherapy and raised just shy of £1,500.  SITA gratefully acknowledges the generosity of BBG Distribution, Rod Roddenbury, and everyone who donated something yummy for the two Christmas Hampers.

There were more reasons to celebrate success and the party was the perfect place for SITA to thank and honour Douglas Nash of PADI.  He is retiring shortly after more than 32 years service to the Industry.  Vini Howlett, Chairman of the Scuba Industries Trade Association presented Doug with an engraved decanter whilst highlighting key aspects of Doug's career.

On the product front, the 2011 UK Diving Trade Show saw the British debut of more than 50 products including Fourth Element's Core Body Warmer, Storm Jacket and Arctic one piece.  "This was a good opportunity to meet many of our UK Dealers and will form an important part of our UK activity in years to come", stated Jim Standing.

Meanwhile, over on the Hollis / Oceanic stand Kelvin Richards stated, "I did not get much of an opportunity to go and listen to the speakers due to the overwhelming work load. This was the UK unveiling of the Hollis Explorer Rebreather and there was huge interest in it.  It made me proud to see the trade platform come back into our industry and Oceanic/Hollis will certainly support all future trade events".

The Poseidon stand was also packed, as Simon Morris launched 46 new products.  "It was important to us to showcase our latest equipment range to the UK Diving Industry who couldn't make it over to Orlando for DEMA". New products include the "One" wetsuits, Rebreather wing, Rebreather BCD with the counter lungs built in, line cutters, wet boots, rash vests, iPAD holder, laptop bag, stage cylinder bag and fins.

Attendees included Chris Wake of Christal Seas Scuba who left his newly constructed dive centre and drove over from Norwich "to meet up with suppliers and other people in our Industry.  I found it useful catching up with industry personnel I've not seen in ages and the social side was great.  It was well worth attending".

Premier Diving Equipment, a new company to the diving industry attended the UK Diving Trade Show for the first time.  "We came to meet people we've been talking to for the last 12 months", explained Rachael Bell.  "We've made a lot of new contacts and it was good to be able to spend time with key players and explain our product range to them.  The talks were really interesting, especially Neal Pollock's Thermal Stress because we're just about to launch a heated vest.  I think what's equally important is that from a personal point of view, I really can't wait to get out and do some more UK diving"!
