The Paddlewheel attachment will attach to any Smart Troll II probe to ADD SPEED data to the mix. With the Paddlewheel Attachment in place the Smart Troll II Probe transmits depth, temperature and SPEED data. You can use multiple Paddlewheel Attachments on multiple Downriggers at the same time.

All 6 Smart Troll Probes will send SPEED data if they are used along with the Paddlewheel Attachment.
