What electronics do you consider "necessary" for Ontario trolling?

[Adk1]

I have an Eagle Ultra ( 1995 Version) w/surface speed & temp, I also have a hand held Magelan  GPS. Also a permanant VHF Radio on my 21' 'hardtop .

No down speed & temp,although I must admit, There are times I wish  I had it.

 

 I feel I do as well as most on the lake & better than most .

 

 The Electronics are tools to help you catch fish, but nothing beats angler expertise.  Knowing What to use when , and most importantly,WHERE. Location is the most important piece of the fishing equation IMO.

 

 I learned long ago it's not the tools, but the guy using them.

I have the same fishfinder

Get the fishhawk it's worth it the new units are nice smaller probes. Been fishing with speed and temp units since 1986 still fishing with a ray Jeff 285 camandtroll . Put new raymarine combo depth/GPS on this yr. go with as big a screen as possible. I'm still using my garmin GPS from1995 as backup that and marine radio. Good to go. Don't need spend a lot . Get quality products. I would much rather fish on a boat. With speed and down temp. Then without. Had that before GPS bac in the 80s dodger squid speed critical. With the big metal blades.
