Gear

Scooter prop pitch adjustment modification
    1. Has made pitch adjustments quicker and easier with gloved / cold hands
    2. Two types of modified adjustment knobs shown (left is hybrid, right is standard)

The following are photo's of the Gavin Scooter rigged without offside (non-trigger) handle

Adding weight to a Halcyon Helios 13.5 below (lead bars are same length as battery pack and provide 4.5 pounds of additional weight)

Diving Watch band (less than $1)
    1. Buy about 1 foot of nylon tube webbing (1/2" to 1" wide)
    2. Buy about 2 feet of small bungee cord
    3. Remove old watch band
    4. Cut 2- 1/2" wide pieces of webbing and slightly burn the edges to reduce fraying
            (the pieces should be cut no wider than the width of old watch band)
    5. Place a piece of the cut webbing into each side of the watch using original watch pins
    6. Cut a piece of bungee according to the size of your wrist as you would wear it underwater
            (mine was roughly 15", but the cord is cheap and you can adjust for anything)
    7. Keep an extra set of webbing pieces and cord in case you ever need to re-do the band

Cave Line Cutter (less than $5)
    1. Buy 2' of regular 2" weight belt webbing
    2. Acquire SS serrated steak knife, cut blade and round the edge
    3. Have shoe repair or saddle repair person sew the webbing as shown

Cold water drysuit heating for long decompression (Idea from Wkpp Europe/ Buchally and Waldbrenner)
     1. Uses standard Gavin Scooter tube for battery (other canisters/battery types will work, too, just be
        certain everyone on the team has the same type of u/w drysuit plug)
    2. Old scooter battery rewired for 12v
    3. Simple 2 pole trailer plugs for battery and internal suit plug in
    4. Marshal Underwater pluggable cord/connectors for drysuit and battery compartment endplate (~$70)
    5. 1" pvc end plates machined for u/w cord and switch, then add ss latch strikes
    6. Kreamer Sports heated polypro underwear (~75watts of power) custom to fit (~$125)
        (heating wire can be run any way you request; the photo shows the underwear with heating
        wire on the upper torso and arms to the elbow, the lower body to the knee)
    7. The underwear can be worn with just the top, bottom, or both
    8. Make certain all buoyancy issues are addressed when wearing the underwear
    9. More photo's coming on various canister styles/sizes, including the standard Pro 14 canister
