Using the scooter safely

Caution!
Rules for safe use of scooters are subject to compulsory diver training hence the user should first and foremost follow the rules provided during specialized training on how to use a scooter. 

Below, only some elements related to the safety and use of the Seacraft scooter are presented. 

• Please read the scooter’s and the charger’s manual as they contain important precautions, warnings and information.
  It is essential that it is carefully and fully read before using the scooter.
• The scooter may only be used by persons with appropriate training in this field. It is strongly forbidden to use the scooter without obtaining special qualifications for diving with a scooter.
• Using the scooter for purposes other than those specified in this manual or in violation of the rules set out in this manual may result in serious personal injury or even death.
• It is forbidden use the scooter to descend and to pull you to the surface of water.
• Be careful with the propeller. Keep away from the rotating propeller as it may injure you.
• For carrying the scooter, always use the handle. Do not carry or pull the scooter by the nozzle.
• Always check the level of batteries before entering the water.
• Remove all objects from the vicinity of the scooter‘s nozzle and propeller before every dive in order to prevent them from being drawn into scooter ‘s power unit.
• Using DPV charger in a manner inconsistent with manual instructions, in particular in conditions of high humidity or when the power cord is damaged may present a risk to the user’s health or life. Do not touch any part of scooter‘s charger with wet hands. 
• It is forbidden for children and adolescents under 18 years of age to use the scooter, or to leave the device unattended.
• Before transporting scooter, ensure it is packed in a way that prevents it from damage during shipping.

Safe diving with a scooter

Before beginning each dive, you need to do the following

• Charge the battery to full (→ Charging the battery).
• Balance the scooter (→ Trimming the scooter).
• Make a decision regarding the point of return for your dive according to air consumption, water temperature etc.
• Check, if your regulator needs to be adjusted.
  With some regulators, you need to make sure, that the second stage does not give a free flow, when the main membrane is pressed by the raised water pressure caused by the scooter’s speed. To avoid a free flow, the breathing resistance of most second stages can be adjusted. Make sure to adjust both second stages (if present).

During every dive, you need to do the following

• Control the battery charge level on a regular basis, taking into account the required battery level for the return dive.
• Use the scooter with optimal, medium speed, which allows for longer battery life.
• Control the level of air consumption on a regular basis. Too fast flow rate or incompetent use of the scooter may result in activating the regulator and thus the loss of breathing gas.
• Control the level of hypothermia. The fast pace movement of the diver with an scooter can lead to faster than normal cooling of the body by increasing the exchange of heat with the environment.
• The scooter is only to be used moving under water on a horizontal plane at a constant depth.
• Follow the safety rules relating to the determination of the time of return; i.e.:
  – Adjust your decision regarding the turning point (return), taking into account the air consumption and battery discharge of the scooter.
  – Regularly check and control the level of the battery discharge.
  – Follow the rules learnt during training concerning DPV usage organized by recognized training organizations.
  – Follow the below procedures in case of scooter failure.

How to react in case of scooter failure while diving

In the case of automatic shutdown of the scooter while diving and / or lack of reaction to start attempts, do the following:

• Immediately abort the dive and (maintaining appropriate procedures) ascend to the surface.

In the case of the scooter blocking and / or the inability to switch it off with the main switch, do the following: 

• Perform the necessary decompression stops swimming with the scooter or
• Unhook the harness / cut off the harness and abandon the scooter or 
• If the diver has a sufficient supply of air, in a controlled manner lean the front of the scooter on the bottom of the water tank or on other permanent items in the water and wait until the battery power of the device runs out or
• Abandon the scooter under water if its towing would be impossible or too burdensome.

After the end of a dive, follow this routine

Caution!
Intense diving with a scooter lasting longer than a normal dive can cause fatigue and hypothermia even with experienced divers. 
So, be prepared to assist them.

• Assist the person using the scooter when leaving the water. 
• Ensure that the person using the scooter has help while the scooter is being transferred, e.g. to the boat or to the shore. Failure to follow the aforementioned instructions may cause injury.

Potential Risks and Solutions during the use of a scooter

This Seacraft scooter offers you 3 different control modes. It is recommended, that you check the mode setting before each dive (→ Control mode).

Also, train to get to know your scooter. Learn how to stop it fast and how to control it responsibly.

Your personal skills and your physical / mental state of the day

Even if you are an experienced diver, do not overly rely on your skills, when you are not familiar with this scooter. Consider the following:

• Take your time to get to know this scooter step by step, in order to avoid a so-called “task overload”, that could distract you from controlling your dive. Hence, it is recommended, that initially you use scooter without accessories and in lower gears.
• Do not exaggerate your first dives with the scooter with regard to maximum depth, diving time and water temperature.
• Plan for a higher air consumption than normal, because you might experience a completely new and exciting way to dive.
• Return to the shore or boat in planned intervals (observing the general rules of diving), in order to talk about your experiences and to change the scooter settings step by step. 

Scooter awareness

If you have no or little experience with scooters, you should remind yourself every now and then during the dive, that you are connected to a powerful and somewhat bulky object.

Observe the rules for entering and leaving the water (→ Entering the water with the scooter).

Uncontrolled descent / ascent

Do not use the scooter during descent and ascent. You might loose control of your descent or ascent speed, which can lead to severe injuries or decompression sickness. Therefore switch off the scooter during these phases of your dive or at least wait, until the scooter automatically returns to gear 0).

Deviating from the planned dive depth

Using the scooter during a dive, you should always keep in mind that the use of this device can greatly mitigate errors in determining correct buoyancy, which, when stopping the scooter may cause sudden, uncontrolled ascent or descent of the diver.
Accordingly, each time before using the scooter check the neutral buoyancy of the scooter. When being pulled by the scooter, regularly check your depth by means of your diving computer or with the scooter accessories.

The scooter is only to be used to move in the water on a horizontal plane at a constant depth.

Improper speed

Never underestimate the power of your scooter, which directly translates to a horizontal speed much higher than you might be used to. Hence, always select the right gear for the given situation.

Propeller-related problems

Again, never underestimate the power of your scooter, which directly leads to a considerable water displacement. Therefore, adapt your personal trim and your relative position to the scooter accordingly (→ Installing the harnesses).

Make yourself familiar with the important aspects regarding the propeller (→ Safety rules regarding the scooter’s propeller).

Accessory- and equipment-related problems

Make sure, that all accessory parts used on the scooter and all parts of your diving equipment are properly fastened and do not create a problem while using the scooter.

A Seacraft specialty: Silent run

Your Seacraft Scooter will run considerably more quiet than other scooters on the market.

With this scooter, it is very likely that even an (also silent) rebreather diver will see you under water, before he/she hears you. So, do not rely on other divers being aware of your presence, because they hear the „typical” buzzing scooter sound long before they see you – they will not.

And yet one more Seacraft Specialty: Reverse gear

Unlike other scooter models on the market, this Seacraft Scooter allows you to move backwards under water, by being „pushed” by the scooter (if the scooter was set to “Expert” or “Recreational” mode (→ Control mode).

Before you activate the motor in gear [R], prepare yourself for the effect of the reversed water flow through the drive unit:

Look behind you and make sure, that there is enough space for manoeuvring.

Make sure, that no part of your equipment is hanging down into the stator area.

With one hand, hold the lower part of the scooter’s noozle, to push it away from your body in 2-points. Simultaneously this will tension the harness lines, to prevent them from being “swallowed” into propeller. Tense the muscles in the arm with the hand holding the scooter. Remember, that the scooter will push you now, so you should put on a certain „resistance”.

Safety rules regarding the scooter’s propeller

Caution!
A rotating propeller is a dangerous element.
Despite the intrinsic security it may cause serious injury.
Never insert, place hands or any objects into the scooter nozzle or rotating propeller blades. It is recommended not to remove the stator.

Before using the scooter

• Ensure that none of the elements mentioned above can become entangled in the scooter propeller.

While using the scooter

• Regularly check whether loose items of equipment are located at a safe distance from the scooter propeller and there is no danger of entanglement of these elements in the scooter propeller mechanism.
• Take special care when maneuvering the scooter in an area with rich vegetation or low visibility waters, where there are obstacles such as: nets, cables, wrecks. It is recommended to turn off the scooter until you leave the area with the above characteristics in order to avoid the possibility of entanglement of those elements in the mechanism of the scooter propeller.

Entaglement of foreign objects in the propeller

In the case of entanglement of ropes or other unwanted items into the scooter propeller mechanism, users of the device should first of all try to solve the problem under the water by taking the following actions:

• Turn off the scooter.
• Untangle or (if possible) cut unwanted items tangled in the scooter propeller.
• The removal of unwanted items is greatly helped by removing the propeller under water (→ Removing the propeller). Note, however, not to use cutting tools to remove the propeller, as this could damage the engine.
• Start the scooter again and choosing the shortest way back, take the return course.

If the foreign objects cannot be removed successfully, proceed as follows:

• Turn off the scooter.
• Independently tow the blocked scooter choosing the shortest way back.
• Ascend to the surface, whilst maintaining usual safety rules.

Ehtical and environmental aspects

Keep the following in mind, while using the scooter:

• Exercise caution in context of caring for the natural underwater environment.
• Pay attention to the appropriate position of the scooter and fins while swimming past delicate underwater formations, so that equipment and diving accessories do not damage elements of flora or fauna.
• Avoid direct contact between the scooter and the bottom/sea bed; making contact with the bottom may result in deterioration of visibility under water, damage to flora or fauna, as well as blocking the scooter propeller (e.g. silt or sand getting into the mechanism as a result of the scooter contact with sea bed).

Worn or broken elements of the scooter must be disposed of in accordance with the applicable laws. Used batteries which are a component of the scooter must be returned to the manufacturer or supplier of the equipment or given to a collection point for used accumulators and batteries or electronic scrap.
