Salmologic – Iceland Outfitters



High end fly fishing equipment

Salmologic is a fishing tackle brand started by Henrik Mortensen in 2014. After designing and developing fly fishing rods and lines for the world’s leading fly tackle companies for over 30 years, he has finally started to produce his own rods under the name Salmologic. Most people are familiar with Henrik, but at the same time being one of the main rod and line designers of our time, he has published a number of fly casting videos and a book that has been translated into many languages. Henrik is one of the world’s leading flyfisherman and has received countless nominations and awards.

Salmologic has only one goal and that is to produce excellent fishing tool and nothing is saved to achieve maximum results. The fly rods are manufactured in South Korea, where Henrik has been with one leg over the years in rod design and quality control. The reels are manufactured in Germany by the same professionals and in the same factory that produces parts in Mercedes Benz. The lines are manufactured in the Rio factories according to Henrik’s formula, but as many know, Rio has been a world leader in fishing lines.

To make it easier for people to choose fishing gear that suits them, Henrik has created a tablet called the G&G system. There, the rod is selected based on the size of the flights most often use. Rod numbers differ between manufacturers and therefore everyone should be able to choose the most suitable fishing gear based on this simple formula.  Here below you can find what size rods would suit you the best.  Just find the fly sizes you most often and then you see it.  

What do we like the most about Salmologic tackles?   Apart from being the best rods and lines we have ever tried, it is all so simple.  If you own a 18 g rod, you buy 18 g line and 18 g leaders (in different weights) and it is color coded which makes it very handy on the bank when changing leaders.


Salmologic rods, reels, lines and leaders are recommended in grams and grains, thereby enabling the customers to make the right decisions when they are setting up their tackle for fishing.

The fact is that every line class has its own fly sizes and it is therefore important to purchase the right line weight according to the fly sizes you normally fish with.

Let me give you an example: If you normally fish for sea trout or salmon in a low glassy river and you use double hook sizes between 8 and 12, or with small cone head brass tubes, then a really good line weight to match those conditions and fly sizes (in my opinion), would be around 20 grams/308 grains.

To make sure your tackle is well-balanced, you would then need a rod that loads perfectly with 20 grams and a leader with the correct mass to turn over that fly size and, even more importantly, balance the speed between the upper and lower line in your loop going forward. Believe me, the leader is the most important part of your equipment and it is completely overlooked.

We, at salmologic, know the physics and the dynamics in a fly cast and how everything should be combined together. Therefore, we have decided against using the confusing AFTM system. Instead, we use what we call our G&G System – Grams and Grains System – because it makes sense. This is the only sure way that a fly fisherman has a chance to make the right decision when assembling his/her gear. Nothing gives an angler a better start in fly casting/fly fishing than the confidence that the tools he/she is using are actually perfectly “made to match” and balanced correctly.

LINE WEIGHT VERSUS FLY SIZE – what size rod should I choose?

The starting point is always to consider which type of fly you would need for the water you are fishing. When you know which size of fly you are going to put on the leader, then you will also have an idea of the line weight needed. For example, a large and heavy fly takes a heavier line and a strong front tapering (which equals a higher line weight), in order to be able to cast and present the fly properly. The following table is a list of different line weights and what I believe are the fly sizes that match those line weights for trout- and salmon fishing.

 The weight listed below is the loading weight for any of our line systems. The weights listed are the actual weight for a shooting head, or the weight of a belly if it is a weight forward line. Do notcount or include the leader’s actual weight as part of the loading weight. The leader has a completely different function in a cast. It is a mass (air and weight resistance) that balances the speed between the upper line and the lower line when the loop is traveling forward. It is not part of the line weight that loads the rod and should therefore not be calculated as line weight.

If I had to go into more detail here, this recommendation would turn into a long and detailed article, so please just take my word for it.

All our leaders are measured to have the correct mass for each line weight. Using Logic coated leaders gives you the practical advantageof allowing you to have more control over which water column your fly will be fishing.

salmologic's mission

“To provide the global fly fishing community with products, services and resources, which are based on innovative designs and logical solutions of supreme quality”. 

Salmo” is the first word in the Latin description of the Atlantic salmon (Salmo salar) and the brown trout (Salmo trutta) family.

Fly fishing for Atlantic salmon and brown trout is our area of expertise, which is why the design and development of our tackle primarily will be focused on this. It is no coincidence that the entire team behind Salmologic consists of a group of highly dedicated and passionate Atlantic salmon and sea run brown trout fly fishermen.

The second part of our brand name is “logic” and represents one of our main goals; to provide logical fly fishing solutions through the products and services that we deliver.
