The kit's buyer guide

This is the page The Fishing Boat Electronics Planner points to. Prices change too often to print, so the worksheets name each product and this page gives its budget range and a link to Amazon's current price. Copy prices onto the Budget Planner on the day you check them.

Budget ranges are a guide, not a quote; the price on Amazon at checkout is the one that counts.

Three complete setups

A boat with a console, a transom and somewhere to put batteries. The binding constraints are console space and budget, and the sonar is always the first upgrade worth making.

$ Starter setup under $2,000 total

The lowest total cost to a boat that finds fish, holds position and is wired safely. Full reasoning: beginner boat electronics rig.

$$ Buy-once setup under $7,500 total

The buy-once boat: side imaging, GPS anchoring and a lithium bank on a real fuse block. Full reasoning: intermediate boat electronics rig.
