I've been using scooters for 13 years and personally to date own five scooters. I have three Farallon MK 8's and one MK 7. I also own one Gavin. I use my Mk 8's on dives that are very long and do not require complicated deco stops in areas were you have to hang, as the MK 8"s are long and heavy. The Gavin is used on deep dives were deco stops on out croppings and heavy currents are a must, for Example the Joydrey. I prefure to dive my MK 8's because of there exstremely long range burn time and excellent and reliable electronics, plus a very strong motor. 13 years and No problems with my Farallons. I like my Gavin because of its incredible buoyancy very light and easily clipped of while standing at deco stops. I must say thou that in the four years of owning my Gavin the motor has failed twice once only three months from new and one plastic weld cracked, but things like that happen when you are running these scooters at deep depths and at times in not so freindly environments. Years back I did have a AquaZepp than ran like a Rolles Royce but parts became hard to get a hold of so I sold it off. Photo attached.
