Yes, we recommend it! Additionally, See below for our Adult Tube Kit Recommendation
-Rip Current Sports recommends parents of 4 and unders purchase the Junior Dual Boards with or without the Adult Tubing Kit.
-Rip Current Sports recommends parents of 5 to 13 year olds purchase the Junior Dual Boards plus the Adult Tubing kit, the Adult Tube Kit is more important for the older user and for those with larger arms.
-Note to customer, the Adult inventor of Dual Boards has done an entire workout with the Junior Dual Boards on his hands – if you elect not to purchase the Adult Tubing Kit because you don’t think your child’s arms are large enough yet, you are probably making the correct decision and can afford to wait to purchase the Adult Tubing Kit another day.
Yes! Also, see the answer to question 1 above. Additionally, for your situation, should your 8-year-old boy complain the wrist is too tight, you may eventually elect to replace the Junior Wrist tubes with the medium size tubes from your Adult Tubing Kit. See How to Assemble Adult Tubing Kits.
Putting Your Dual Boards on Your Hands (See Pictures Below)
There are multiple ways to put on Dual Boards. Rip Current Sports recommends: the user get into the shallow end of the pool; get their Dual Board tubing wet and get their arms wet. Then, put them on using the 5-4-2 Method: Put 5 fingers under the wrist tube; Put 4 fingers under the hand tube where you leave the thumb on the recessed feature of the Board; Put 2 fingers under the finger tube where you leave index finger and pinkie on the outside of the finger tube.
Note to Customer – There is no glue on Dual Boards. In the event a tube comes off of a rivet; immediately grab the rivet, wet the tube, push the tube through the hole so roughly one inch of tubing is seen out of the Board’s subsurface, put the rivet through the tube end so the tube end almost reaches the flat part of the rivet; then slowly push the rivet into the hole until the flat part of the rivet lies flat on the Board’s subsurface. Note to Customer – In the event Customer loses a rivet, all Dual Boards come with an extra rivet. Should the swimmer not have the rivet with them, at that moment, carefully pry the other rivet and tube ensemble off of the Board, put the two, preferably together still, in your swim bag and continue using your Dual Boards until you grab your extra rivet and reassebmble the wrist tube according to guidance provided in How to Assemble Adult Tubing Kits. Note to Customer – In the event Customer loses the extra rivet, Rip Current Sports Intends to sell rivets on the Rip Current Sports website. Stay Tuned at ripcurrentsports.com
