Spares and add-ons for the Global Water Flow Probe.

• Propeller kit — the propeller is the part that takes the damage from gravel, trash racks and debris. A fouled or chipped propeller reads low, so it is worth carrying a spare rather than trusting a bent one.
• Digital flow computer — upgrade display for the FP111 and FP211.
• Carrying cases — sized separately for the FP111 and the longer FP211 rod. Order the case that matches your rod length.

Contact us with your model if you are unsure which part you need.
