Bought a Traveller, powered it with 12ah, 20 amp de-walt batteries. Lots of run-time! I also wanted it for blasting away sediment while searching for old glass & crockery. In this regard, the scooter is great for removing light sediment and sand, but has limited effect on firmer sediments like clay. Sand tends to affect the on/off switch, but I can clear it fairly easily. Fishing line is a pain & I've had to pop the prop off several times to clear it from the hub. What I really enjoy is long runs in rivers, exploring as yet unseen territory. Initially I had issues with the scooter simply stopping for no apparent reason, restarting after several seconds. A firmware update fixed that. Can't wait to get it down to Roatan for some extended reef exploration!
