TROLLING, What depth?

[MastaPike]

With downriggers I prefer to fish at 10-15m depth. Big depth = big fish

Fishing pikes in summertime does not necessary means fishing deep. I normally never use downriggers. Most pelagial pikes are taken by baits that swims between 1-5 meter such as Bomber, Swim Whizz, SSR, Rapala Magnum etc. The last trip did result in two 12 kg pikes taken over 100 depth with Bomber and SSR fishing at a planer.
If I though would use a downrigger I would prefer fishing around 10 meter or as Waterlog already said around the termoclinic.
