Marcus on abuse. Look for a castable fish finder with a clear IP rating and low weight. Confirm the pack size fits your tackle box before buying.

I test gear for wet deck duty, where rain, dust, and miles of casting wear down electronics. A castable fish finder must handle this abuse without failing.

Check the Amazon listing for the IP rating, weight, and pack size. These details must match the product description to ensure it survives your conditions.
